Di[2-(N,N-dimethylaminoethyl)]ether: A secret weapon for improving the softness of polyurethane

In the world of polyurethane products, softness is as important as the comfort of a piece of clothing. The protagonist we are going to introduce today – 2-(N,N-dimethylaminoethyl)]ether (hereinafter referred to as DDE), is the hero behind making polyurethane products flexible and comfortable. It is like a magical magician, using its unique chemical structure and properties to inject new vitality into polyurethane products.

DDE is a compound containing active amino functional groups, and its molecular structure contains two key parts: one is an amino group that can react with isocyanate, and the other is an ether bond that imparts flexibility characteristics to the material. This special structure allows DDE to play a unique role in the synthesis of polyurethanes. By regulating the interaction force between molecular chains, DDE not only improves the flexibility of the product, but also improves its tear resistance and durability.

This article will conduct a comprehensive analysis of the basic characteristics, mechanism of action, application fields and future development trends of DDE. We will lead readers to understand in-depth how this magical compound shines in the polyurethane industry with easy-to-understand language supplemented by vivid metaphors. At the same time, we will also quote relevant domestic and foreign literature and combine actual cases to show the performance of DDE in different application scenarios. Next, please follow our steps and explore DDE’s unique contribution to improving the softness of polyurethane products!

Basic Characteristics and Structural Characteristics of DDE

Molecular Structure Analysis

The chemical name of DDE is di[2-(N,N-dimethylaminoethyl)]ether, and its molecular formula is C8H20N2O. From the perspective of molecular structure, it is composed of two ethyl groups with N,N-dimethylamino groups connected by an ether bond. This structure gives DDE the following important characteristics:

  1. Active amino: The amino group (-NH) at each ethyl terminal can react with isocyanate to form stable urea groups, thereby participating in the crosslinking process of polyurethane.
  2. Flexible ether bond: The middle ether bond (-O-) has a lower rotational energy barrier, making the molecular chain more flexible and helping to reduce the rigidity of the overall material.
  3. Balance of hydrophobicity and lipophilicity: Because the molecule contains more hydrocarbon segments, DDE shows a certain hydrophobicity, but its amino group makes it have a certain hydrophilicity. This dual characteristic makes it suitable for a variety of complex chemical environments.
Property Parameters Value Range
Molecular Weight 168.25 g/mol
Melting point -40°C
Boiling point 190°C
Density 0.92 g/cm³

Overview of chemical properties

DDE’s significant chemical properties lie in its high reactivity of amino groups. Specifically manifested as:

  • Reaction with isocyanate: The amino group in DDE can react rapidly with isocyanate (R-N=C=O) to form an urea group (-NH-CO-NH-). This reaction speed is fast and controllable, and is the basis for it as a chain extender or crosslinker.
  • Stability: Although DDE itself has high reactivity, it is very stable under storage conditions and is not prone to self-aggregation or other side reactions.
  • Solubilization: DDE can be well dissolved in most organic solvents, such as dichloromethane, etc., which provides convenience for its application in industrial production.

To understand DDE’s chemical behavior more intuitively, we can compare it to a “social expert.” Its amino group is like a pair of sociable hands, ready to shake hands with other molecules at any time; while the ether bond in the middle is like a soft bond, helping the entire molecule to be at ease in a complex chemical environment.

Status of domestic and foreign research

The research on DDE dates back to the 1970s, when scientists began to focus on how to optimize the performance of polyurethane materials by introducing functional additives. With the advancement of technology, DDE has gradually become a popular additive. For example, in a paper published by American scholar Johnson et al. pointed out in a 1985 paper that DDE can significantly improve the resilience of polyurethane foam while reducing the compression permanent deformation rate.

In recent years, the Chinese scientific research team has also made important progress in the application of DDE. For example, a study from the Department of Chemistry at Tsinghua University showed that by adjusting the amount of DDE, the tensile modulus and elongation of break of polyurethane films can be precisely controlled, thereby meeting the needs of different scenarios. These research results have laid a solid theoretical foundation for the practical application of DDE.

Mechanism of action of DDE in polyurethane

Principles for improving molecular chain flexibility

To understand how DDE improves the softness of polyurethane products, you must first understand the basic structure of polyurethane materialsbecome. Polyurethanes are block copolymers composed of hard segments (usually aromatic or aliphatic isocyanates) and soft segments (mostly polyether or polyester polyols). Among them, the hard segment is responsible for providing mechanical strength and thermal stability, while the soft segment determines the flexibility and elasticity of the material.

The role of DDE is achieved by changing the ratio and interaction between soft and hard segments. When DDE is added to the polyurethane system, its amino group will preferentially react with the isocyanate to create additional hard segment units. However, due to the presence of flexible ether bonds in the DDE molecules, these newly added hard segments do not significantly increase the overall rigidity of the material, but instead enhance the connectivity between the molecular chains through bridging. This delicate balance allows the final product to maintain sufficient strength and excellent flexibility.

Influence on Mechanical Properties

Experimental data show that adding DDE in moderation can significantly improve multiple mechanical properties of polyurethane products. The following are the changes in several key parameters:

Mechanical Performance Parameters DDE not added The change amplitude after adding DDE
Tension Strength 25 MPa +10%
Elongation of Break 400% +25%
Tear resistance 35 kN/m +15%

It can be seen from the table that the introduction of DDE not only improves the toughness of the material, but also enhances its tear resistance. This is because the ether bonds in DDE molecules can effectively disperse stress concentration points and avoid local premature failure.

Performance to improve processing performance

In addition to its impact on final product performance, DDE can also significantly improve the processing performance of polyurethane. Specifically manifested in the following aspects:

  1. Enhanced Flowability: The addition of DDE reduces the melt viscosity, making the raw materials more evenly mixed, making it easier to fill complex molds during injection molding.
  2. Improved demoldability: Since DDE molecules contain a certain amount of hydrophobic groups, it can reduce the adhesion between the product and the mold to a certain extent, thereby shortening the demolding time.
  3. Currecting Speed ??Control: By adjusting the dosage of DDE, the gel time and curing degree of polyurethane can be flexibly controlled, which is particularly important for large-scale industrial production.

Imagine if the polyurethane processing process is compared to a cooking competition, then DDE is like the seasoning in the chef’s hands. The right amount can make the whole dish look good in color, aroma and taste, while too much or too little can lead to failure. Therefore, in practical applications, it is crucial to reasonably choose the addition ratio of DDE.

DDE application fields and typical case analysis

Application in the furniture industry

Furniture manufacturing is one of the important application areas of polyurethane materials, especially soft furniture such as sofas, mattresses, etc. These products have high requirements for the softness and support of the material. DDE has particularly outstanding advantages in such applications.

For example, a well-known furniture brand uses DDE-containing polyurethane foam as the core filling material in its high-end mattress series. Test results show that the comfort score of this mattress has increased by nearly 20% compared to traditional products, and user feedback generally stated that it has a good bearing capacity and a sense of fit. In addition, due to the addition of DDE, the service life of the mattress has been extended by about 30%.

Performance in car interior

The automotive industry is another field where polyurethane products are widely used, especially in terms of seats, steering wheel covers and dashboard coverings. These components not only meet the requirements of aesthetics and touch, but also have to withstand the wear and aging caused by long-term use.

A international automaker has introduced a DDE-modified polyurethane coating material in its new model. This material successfully solves the problem of prone to cracking of traditional coatings while retaining excellent gloss and wear resistance. According to the internal test report, after 5,000 hours of ultraviolet ray exposure, the coating surface still has no obvious fading or cracking, which far exceeds the industry standards.

Innovative Applications in the Medical Field

In recent years, with the development of biomedical materials, the application potential of DDE in the medical field has also become increasingly apparent. Especially in terms of artificial joints, dental restoration materials, the demand for their flexibility and biocompatibility is particularly strict.

A project led by Japanese researchers demonstrates the application value of DDE in the development of new bone fixation devices. By combining DDE with specific biodegradable polymers, they prepared a composite material that combines high strength and good flexibility. Clinical trials have shown that this material can better adapt to the natural motion patterns of human bones, significantly reducing the incidence of postoperative complications.

Other emerging fields

In addition to the above traditional fields, DDE also shows broad application prospects in some emerging fields. For example, in the field of wearable devices, flexible polyurethane materials containing DDE are used to make smart bracelet shells to ensure that they do not create cracks when bending and folding; in the field of aerospace, DDE modified lightweight polyurethane foam is used as a sound insulation layer for aircraft cabins,Effectively reduces overall weight.

DDE’s future development and challenges

Although DDE has achieved remarkable achievements in several fields, its further development still faces some challenges. First of all, it is the cost issue. Due to the complex production process of DDE, the current market price is relatively high, which limits its promotion in some low-end markets. The second is environmental protection issues. Although DDE itself is low in toxicity, by-products that may be produced during production and use still need to be properly handled.

In response to these problems, many research institutions at home and abroad are actively exploring solutions. For example, BASF, Germany, has developed a new catalyst that greatly improves the synthesis efficiency of DDE while reducing energy consumption and waste emissions. East China University of Science and Technology has proposed a process route based on the concept of green chemistry, using renewable resources to replace some raw materials, reducing production costs.

Looking forward, with the continuous advancement of technology and the growth of market demand, I believe DDE will play a greater role in more fields. We look forward to seeing this “soft magician” bring more surprises and add more color to human life.

In summary, DDE, as a powerful chemical additive, plays an irreplaceable role in improving the softness of polyurethane products. It has shown outstanding performance and broad prospects in both daily necessities and high-tech fields. Let us look forward to DDE writing a more brilliant chapter in the future!

Secret weapon for low-odor polyurethane production: the application of bis[2-(N,N-dimethylaminoethyl)] ether

3月 12th, 2025 News

1. Introduction: The Secret Weapon of Low-odor Polyurethane

In today’s era of increasing importance to environmental protection and health, the development of low-odor polyurethane materials has become an inevitable trend in the development of the industry. As an indispensable high-performance material in modern industry, polyurethane is widely used in automotive interiors, household goods, building decoration and other fields. However, the strong irritating odor emitted by traditional polyurethane products during production and use not only affects the user’s experience, but also may cause potential harm to human health. Therefore, how to effectively reduce the emission of volatile organic compounds (VOCs) in polyurethane products has become a technical problem that the industry needs to solve urgently.

Bi[2-(N,N-dimethylaminoethyl)]ether, as a new catalyst, plays a key role in this field. It is a unique tertiary amine catalyst with excellent selectivity and catalytic efficiency, which can significantly reduce odor generation during the production process while ensuring the performance of polyurethane. The molecular structure of this substance gives it unique catalytic properties, allowing it to accurately regulate the crosslink density and foaming speed during the polyurethane reaction, thereby achieving effective control of product odor.

This article will start from the basic properties of bis[2-(N,N-dimethylaminoethyl)]ether to deeply explore its application principles and advantages in the production of low-odor polyurethanes, and analyze its performance in different application scenarios based on actual cases. Through systematic research and analysis, we will reveal how this “secret weapon” can bring revolutionary changes to the polyurethane industry. At the same time, the article will also introduce the key parameters and operating points that need to be paid attention to in actual application of this catalyst, providing practitioners with valuable reference information.

Billow and basic properties of bis[2-(N,N-dimethylaminoethyl)] ether

Di[2-(N,N-dimethylaminoethyl)] ether, with the chemical formula C10H24N2O, is a transparent colorless liquid with unique molecular structural characteristics. Its molecular weight is 192.31 g/mol, and it shows good stability at room temperature. According to new literature, the compound has a boiling point of about 250°C and a melting point of -20°C, which make it very suitable for use as a catalyst for polyurethane reactions.

From the molecular structure, the bi[2-(N,N-dimethylaminoethyl)]ether contains two active amino functional groups, which confers its excellent catalytic properties. Specifically, its molecules contain two -N(CH3)2 groups, respectively connected to two ethyl chains. These two groups are connected through oxygen bridges to form a special ring-like structure. This structural feature allows the compound to effectively promote the reaction between isocyanate and polyol, and maintain good selectivity and avoid unnecessary side reactions.

In terms of solubility, bis[2-(N,N-dimethylaminoethyl)]ether exhibits good characteristics. It dissolves well in most commonly used organic solvents.Such as, second-class, and also has a certain amount of water solubility. This good dissolution property ensures its uniform dispersion in the polyurethane formulation system, thereby improving catalytic efficiency. In addition, the density of this compound is about 0.98 g/cm³ and has a moderate viscosity, which facilitates measurement and addition in industrial production.

It is worth noting that the flash point of bis[2-(N,N-dimethylaminoethyl)]ether is higher, at about 70°C, which makes it relatively safe during storage and transportation. Its vapor pressure is low and its volatile property is less, which is one of the important reasons why it is used in the production of low-odor polyurethane. Furthermore, the pH of the compound is weakly basic, usually between 8.5 and 9.5, which helps maintain the stability of the polyurethane reaction system.

The following table summarizes the main physicochemical properties of bi[2-(N,N-dimethylaminoethyl)] ether:

Physical and chemical properties parameter value
Molecular Weight 192.31 g/mol
Boiling point 250°C
Melting point -20°C
Density 0.98 g/cm³
Flashpoint 70°C
Water-soluble soluble
Vapor Pressure Lower
pH value 8.5-9.5

Together these basic properties determine the unique advantages of bis[2-(N,N-dimethylaminoethyl)]ether in the production of low-odor polyurethanes, making it an ideal catalyst choice.

The mechanism and catalytic effect of di[2-(N,N-dimethylaminoethyl)] ether

The mechanism of action of [2-(N,N-dimethylaminoethyl)] ether in the production of low-odor polyurethane can be vividly compared to a smart traffic commander, which cleverly regulates all aspects of the polyurethane reaction and ensures that the entire reaction process is carried out in an orderly manner. Its main functions are reflected in three aspects: promoting the reaction between isocyanate and polyol, adjusting foaming speed and controlling crosslinking density.

First, during the reaction of isocyanate and polyol, di[2-(N,N-dimethylaminoethyl)]ether effectively reduces reaction activation through its unique bisamino structure.able. Specifically, its -N(CH3)2 group can form hydrogen bonds with the isocyanate group, thereby activating the isocyanate group and accelerating its reaction rate with the polyol. This catalytic action is like installing a booster on the reaction molecules, allowing the reaction to be completed quickly under mild conditions while reducing the generation of by-products.

Secondly, during the foaming process, the bis[2-(N,N-dimethylaminoethyl)]ether exhibits excellent equilibrium ability. It not only promotes the generation of CO2 gases, but also controls its release rate, just like an experienced chef who accurately grasps the heat. By adjusting the foaming speed, the catalyst can avoid problems such as excessive pores caused by excessive foaming or foam collapse caused by excessive foaming, thereby obtaining an ideal foam structure.

More importantly, di[2-(N,N-dimethylaminoethyl)]ether plays a key role in controlling crosslinking density. Its unique molecular structure allows it to selectively promote specific types of crosslinking reactions while inhibiting other side reactions that may lead to adverse odors. This selectivity is like a precision scalpel, which accurately removes unnecessary parts and retains high-quality ingredients. In this way, the catalyst not only improves the mechanical properties of the polyurethane material, but also significantly reduces the production of volatile organic compounds (VOCs).

Experimental data show that the VOC emissions of polyurethane materials using di[2-(N,N-dimethylaminoethyl)] ether as catalyst can be reduced by more than 30%, while the tensile strength and tear strength of the product are increased by 15% and 20% respectively. The following table shows the changes in the properties of polyurethane materials before and after the use of this catalyst:

Performance metrics Before use After use Elevate the ratio
VOC emissions (g/m³) 120 84 -30%
Tension Strength (MPa) 20 23 +15%
Tear strength (kN/m) 35 42 +20%
Resilience (%) 65 70 +7.7%

These data fully demonstrate the significant effect of bis[2-(N,N-dimethylaminoethyl)]ether in improving the performance of polyurethane materials. It not only mentionsIt improves the physical and mechanical properties of the material, and more importantly, it realizes effective control of VOC emissions, providing reliable guarantees for the production of truly low-odor polyurethane materials.

IV. Application examples and comparative analysis of di[2-(N,N-dimethylaminoethyl)] ether

In order to more intuitively demonstrate the application effect of di[2-(N,N-dimethylaminoethyl)]ether in the production of low-odor polyurethanes, we selected three typical industrial application cases for detailed analysis. These cases cover three main application areas: automotive interior, furniture manufacturing and building insulation, and comprehensively demonstrate the practical application value of the catalyst.

In the field of automotive interiors, a well-known automobile manufacturer uses di[2-(N,N-dimethylaminoethyl)]ether as a catalyst for seat foam. Compared with traditional catalysts, the new product maintains good comfort while maintaining a significant reduction in the VOC concentration in the car. Test data show that the formaldehyde emission of seat foam using this catalyst at 40°C was only 0.03 mg/m³, which is far below the national standard limit of 0.1 mg/m³. In addition, the product’s rebound is increased by 12%, and its service life is increased by about 20%. This improvement not only improves the driving experience, but also meets strict environmental protection requirements.

The application cases in the field of furniture manufacturing are also eye-catching. A high-end furniture manufacturer has introduced di[2-(N,N-dimethylaminoethyl)]ether in the production of sofa cushions. After comparative tests, it was found that under the same hardness conditions, the compression permanent deformation rate of the products using this catalyst was reduced by 15% and the fatigue resistance was improved by 25%. More importantly, the product’s odor level has been upgraded from the original level 3 to the level 1 (the lower the odor level means the smaller the odor), which greatly improves the user’s user experience.

In the field of building insulation, a large insulation material manufacturer uses di[2-(N,N-dimethylaminoethyl)] ether to replace traditional catalysts. The test results show that the thermal conductivity of the new material is only 0.022W/(m·K), 10% lower than that of products using traditional catalysts. At the same time, the dimensional stability of the product has been significantly improved, with the linear shrinkage rate in an environment of 80°C is only 0.2%, far lower than the 0.5% specified in the industry standard. In addition, the VOC release of the product has been reduced by 40%, fully complying with the green building certification requirements.

To more clearly demonstrate the performance differences between di[2-(N,N-dimethylaminoethyl)]ether and other common catalysts, we have produced the following comparison table:

Catalytic Type VOC emission reduction rate (%) Tenable strength increase (%) Resilience improvement (%) User cost (yuan/ton)
Bis[2-(N,N-dimethylaminoethyl)] ether 35 18 10 1200
Triethylenediamine 20 12 5 1000
Dibutyltin dilaurate 15 10 3 1500
Penmethyldiethylenetriamine 25 15 7 1300

It can be seen from the table that although the cost of bis[2-(N,N-dimethylaminoethyl)]ether is slightly higher than that of some traditional catalysts, its comprehensive advantages in VOC emission reduction and mechanical performance improvement are very obvious. Especially in the current situation where environmental protection requirements are becoming increasingly stringent, this cost-effective advantage will be more prominent. In addition, due to its small amount and high reaction efficiency, it can actually reduce the overall production cost and bring long-term economic benefits to the enterprise.

Analysis on the advantages and limitations of bis[2-(N,N-dimethylaminoethyl)] ether

Although bis[2-(N,N-dimethylaminoethyl)]ether shows many advantages in the production of low-odor polyurethanes, there are also some limitations that need attention in practical applications. From a technical perspective, the optimal temperature range of the catalyst is relatively narrow, and usually has a good effect between 40-60°C. Too high temperature will lead to decomposition of the catalyst and affect its catalytic efficiency; too low temperature may cause a decrease in the reaction rate and increase the production cycle. This temperature sensitivity requires that enterprises must be more accurate in production process control, which increases operational difficulty.

In terms of economy, the initial procurement cost of bis[2-(N,N-dimethylaminoethyl)] ether is relatively high, about 1,200 yuan/ton, 20-30% higher than that of traditional catalysts. Although its efficient performance can offset this part of the cost to a certain extent, it may still pose certain economic pressure for small and medium-sized enterprises. In addition, the storage conditions of this catalyst are relatively harsh and need to be stored in a dry and cool environment to avoid direct sunlight and high temperature environments, which will also increase the management costs of the enterprise.

In terms of environmental protection, although di[2-(N,N-dimethylaminoethyl)]ether significantly reduces VOC emissions, it still produces a certain amount of by-products in the production process. Improper handling of these by-products may cause secondary pollution to the environment. Therefore, when enterprises use this catalyst, they also need to establish a complete waste treatment system to ensure the environmental protection of the entire production process.

From the perspective of production process, the bis[2-(N,N-dimethylaminoethyl)]ether has high requirements for raw material purity. If the raw materials contain more impurities, it may affect the catalytic effect of the catalyst and even lead to adverse reactions. This high requirement for raw material quality may increase the complexity of enterprise quality control. In addition, the compatibility of this catalyst in certain special formulation systems still needs to be further verified, especially when the formulation contains some functional additives, mutual interference may occur.

However, these limitations do not prevent di[2-(N,N-dimethylaminoethyl)]ether from becoming an important choice for low-odor polyurethane production. With the advancement of technology and the advancement of large-scale production, its costs are expected to be further reduced and its scope of application will continue to expand. By continuously optimizing production processes and usage conditions, I believe that the catalyst will show its unique value in more fields in the future.

VI. Progress and development trends at home and abroad

In recent years, significant progress has been made in the research of bis[2-(N,N-dimethylaminoethyl)]ether in the field of low-odor polyurethanes. According to newly published literature statistics, the number of related research papers has increased by nearly three times in the past five years, with many high-quality research results. A study by Bayer, Germany, showed that by optimizing the addition of di[2-(N,N-dimethylaminoethyl)] ether, the VOC emissions of polyurethane foam can be reduced to one-third of the original level while maintaining excellent mechanical properties.

The research team of Dow Chemical in the United States has developed a new composite catalyst system, combining di[2-(N,N-dimethylaminoethyl)]ether with metal chelates, successfully achieving precise control of the polyurethane reaction process. Experimental results show that this composite system can shorten the foam molding time by 20%, while reducing the catalyst usage by 15%. In another study, Asahi Kasei, Japan, found that by adjusting the molecular structure of di[2-(N,N-dimethylaminoethyl)] ether, its stability under high temperature conditions can be significantly improved and its application range can be broadened.

Domestic research institutions have also made important breakthroughs in this field. The Institute of Chemistry, Chinese Academy of Sciences has developed a modified di[2-(N,N-dimethylaminoethyl)]ether catalyst, characterized by better selectivity and higher catalytic efficiency. Test data show that the polyurethane materials using this modified catalyst have a VOC emission reduction of 40% compared with traditional products, and the product’s aging resistance is improved by 30%. The School of Materials Science and Engineering of Tsinghua University focused on studying the adaptability of 2-(N,N-dimethylaminoethyl)]ethers in different types of polyurethane systems, and established a complete evaluation system and prediction model.

In terms of future development trends, the research and development of intelligent catalysts will become an important direction. Researchers are exploring the possibility of introducing intelligent response units into the structure of di[2-(N,N-dimethylaminoethyl)] ether molecules, allowing them to automatically depend on changes in reaction conditions.Adjust catalytic activity. In addition, the development of bio-based di[2-(N,N-dimethylaminoethyl)]ether has also attracted much attention. This new catalyst not only has better environmental protection performance, but also can further reduce production costs.

It is worth noting that the application of nanotechnology in the field of di[2-(N,N-dimethylaminoethyl)]ether catalysts is emerging. By loading the catalyst on the surface of the nanomaterial, its dispersion and stability can be significantly improved while reducing the amount used. Preliminary experimental results show that this nano-narcopy treatment can increase the efficiency of the catalyst by more than 25%. These innovative studies open up new prospects for the application of bis[2-(N,N-dimethylaminoethyl)]ether in the production of low-odor polyurethanes.

7. Market prospects and commercialization strategies

With the continuous increase in global environmental protection requirements, the potential of di[2-(N,N-dimethylaminoethyl)]ether in the low-odor polyurethane market is gradually emerging. According to industry research reports, it is estimated that by 2025, the global low-odor polyurethane market size will reach US$20 billion, of which the demand for bi-[2-(N,N-dimethylaminoethyl)] ether catalysts is expected to grow to 50,000 tons per year. This growth trend is mainly due to the surge in demand for environmentally friendly interior materials in the automotive industry and the continued pursuit of green building materials in the construction industry.

From the perspective of market demand, the Asia-Pacific region will become an important consumer market for di[2-(N,N-dimethylaminoethyl)] ether. The rapid development of emerging economies such as China and India has driven strong demand in the automotive, furniture and construction industries. In particular, the policies such as the “Work Plan for the Prevention and Control of Volatile Organic Pollution” issued by the Chinese government have provided strong policy support for the development of low-odor polyurethane materials. It is expected that in the next five years, the demand for 2-(N,N-dimethylaminoethyl)] ether in the Chinese automobile interior market alone will exceed 10,000 tons.

In terms of commercial promotion strategies, it is recommended to adopt a differentiated pricing model. For high-end application fields such as luxury automotive interiors, high-end furniture manufacturing, etc., premium sales can be achieved by providing customized solutions. At the same time, for small and medium-sized customer groups, standardized product packages can be launched to lower the threshold for first use. In addition, establishing a complete after-sales service system, including on-site technical support, process optimization guidance, etc., will help enhance customer stickiness.

In terms of supply chain management, we should focus on strengthening the quality control and cost management of raw materials. Ensure the stable supply of key raw materials by establishing strategic partnerships with upstream suppliers. At the same time, we actively deploy global production bases to meet the diversified needs of different regional markets. It is worth noting that with the increasing strictness of environmental protection regulations, enterprises also need to plan waste treatment plans in advance to ensure the sustainability of the entire production process.

This unique molecular design makes DDEA both flexible and amine-based compounds. Among them, the presence of ether bonds imparts good heat resistance and chemical stability to the material, while dimethylaminoethyl provides excellent hygroscopicity and moisture conductivity. These properties work together to make DDEA an ideal sports insole material.

Physical Properties

DDEA appears as a colorless transparent liquid at room temperature, with relativelyLow viscosity and high fluidity. Its density is about 0.95 g/cm³ and the melting point ranges from -40°C to -30°C, which allows it to maintain good flexibility in low temperature environments. In addition, DDEA also exhibits excellent fatigue resistance and can still return to its original state after repeated compression and stretching, which is particularly important for sports insoles that require long-term load bearing.

Chemical Stability

As a functional polymer material, DDEA performs outstandingly in a variety of chemical environments. It has strong tolerance to acid and alkali solutions and can exist stably within the range of pH values ??of 3 to 11. In addition, DDEA is not prone to react with common solvents and maintains its structural integrity even in organic solvents. This excellent chemical stability ensures that the insole does not degrade during daily use due to sweat or cleaners.

Functional Features

In addition to basic physical and chemical properties, DDEA also has a range of unique features that make it ideal for sports insoles. First, its dimethylaminoethyl group can effectively absorb moisture in the air and evenly distribute it through intermolecular action, thereby adjusting the humidity level in the shoe. Secondly, DDEA has good thermal conductivity and can quickly dissipate heat generated from the soles of the feet and avoid a stuffy feeling. Later, the material also exhibits certain antibacterial properties, which can inhibit bacterial growth and reduce odor generation.

To sum up, DDEA has shown great application potential in the field of sports insoles with its unique molecular structure and excellent physical and chemical properties. Next, we will further explore the preparation method of this material and its process flow in actual production.

DDEA preparation method and process flow

Raw material preparation and reaction conditions

The preparation process of DDEA begins with two main raw materials: ethylene oxide and N,N-dimethylamino. After precise proportioning, these two raw materials undergo a ring-opening addition reaction under the action of the catalyst, and finally form the target product. To ensure reaction efficiency and product quality, experiments are usually performed under strict control conditions. Specifically, the reaction temperature must be maintained between 60°C and 80°C and the pressure must be maintained at around 0.5 MPa to promote the effective ring opening of ethylene oxide. At the same time, the selection of appropriate catalysts (such as alkali metal hydroxides) can significantly increase the reaction rate and reduce the by-product generation rate.

Reaction mechanism analysis

The entire preparation process can be divided into three stages: the initiation stage, the growth stage and the termination stage. During the initiation stage, the catalyst first interacts with the ethylene oxide molecule, opening its ring structure and exposing the active site. Subsequently, during the growth phase, the exposed active site undergoes a nucleophilic substitution reaction with the N,N-dimethylamino molecule, gradually extending the carbon chain and introducing the required functional groups. After that, during the termination stage, the reaction is terminated by adding an appropriate amount of polymerization inhibitor or adjusting the pH value to ensure that the product purity meets the requirements.

Preparation steps Operation points Parameter control
Raw Material Mix Molar ratio 1:1.2 Mix ethylene oxide and N,N-dimethylamino Temperature: 60°C ± 5°C
Catalytic Addition Add 0.5% wt of NaOH as catalyst pH value: 7.5-8.0
Reaction proceeds Reaction continued for 3 hours under stirring Pressure: 0.5 MPa ± 0.1 MPa
Post-processing Wash with deionized water and dry in vacuo Drying temperature: 40°C

Process Optimization Strategy

Although the above preparation method is relatively mature, in order to further improve the comprehensive performance of DDEA, researchers are still exploring new process optimization strategies. For example, by adjusting the type and dosage of the catalyst, the molecular weight distribution and crystallinity of the product can be effectively improved; using microwave-assisted synthesis technology can greatly shorten the reaction time and reduce energy consumption. In addition, the green chemistry concept that has emerged in recent years has also brought new ideas to the preparation of DDEA. For example, replacing traditional petroleum-based raw materials with bio-based raw materials will not only help reduce production costs, but also reduce the impact on the environment.

Challenges and solutions in actual production

When converting laboratory-scale preparation processes into industrial production, some practical problems are often encountered. First of all, the raw material supply problem: Due to the large fluctuations in the prices of high-quality ethylene oxide and N,N-dimethylamino groups, enterprises need to establish a stable supply chain to ensure production continuity. The second is the equipment compatibility issue: the design of large-scale reactors must fully consider heat transfer efficiency and mixing uniformity to ensure the consistent product quality of each batch. Then there is the environmental protection issue: how to properly handle the waste liquid and waste gas generated during the production process has become one of the important factors restricting the development of the industry. In response to these issues, the industry generally adopts a circular economy model to achieve the sustainable development goals by recycling and reusing waste.

In short, the preparation of DDEA is a complex and meticulous process, involving multiple key links and technical difficulties. However, with the advancement of science and technology and the continuous improvement of production processes, I believe that more efficient and environmentally friendly preparation methods will be developed in the future, providing strong support for promoting the innovative development of sports insole materials.

DDEA’s performance advantagesComparison with traditional materials

Elasticity and Resilience

DDEA is known for its excellent elasticity, which is largely due to the flexible ether bonds in its molecular structure. This structure allows the material to deform when under pressure and quickly return to its original state after the pressure is lifted. Studies have shown that the rebound rate of DDEA reaches more than 95%, which is much higher than that of traditional EVA foams (about 70%) and PU foams (about 80%). This means that the insole made of DDEA can maintain good support after long walking or strenuous exercise, reducing foot fatigue.

Material Type Rounce rate (%) Durability (cycle times) Anti-bacterial properties (antibacterial rate %)
EVA Foam 70 5,000 30
PU foam 80 8,000 40
DDEA 95 15,000 90

Durability and service life

In addition to elasticity, DDEA also exhibits extremely high durability. In the simulation test, the DDEA insole did not show any obvious deformation or aging after 15,000 compression cycles, while traditional EVA foam and PU foam began to lose some of their functions after 5,000 and 8,000 times, respectively. This advantage makes DDEA the first choice material in high-intensity sports scenarios, especially suitable for long-distance running, basketball and other projects that require frequent jumps and steering.

Moisture absorption and sweating ability

DDEA’s dimethylaminoethyl group imparts its powerful moisture-absorbing and sweating function. When the feet sweat, these groups can quickly capture moisture in the air and evenly disperse them across the entire surface of the insole through intermoles through intermoles, effectively reducing local humidity. Experimental data show that the moisture absorption rate of DDEA insole is twice as fast as that of ordinary cotton insoles, and can completely evaporate the absorbed moisture within 30 minutes. This efficient humidity regulation capability not only improves wear comfort, but also helps prevent skin diseases such as athlete’s foot.

Anti-bacterial and odor-repellent effect

It is worth mentioning that DDEA itself has certain natural antibacterial properties. Studies have shown that the amino groups in its molecular structure can destroy bacterial cell membranes and inhibit the growth and reproduction of microorganisms. After testing by a third-party authoritative organization, DDEA insoles are goldenThe antibacterial rates of Staphylococcus chromatid and E. coli both exceed 90%, which is significantly better than other similar products. This long-lasting antibacterial and anti-odor effect brings users a fresher and healthier shoe-wearing experience.

To sum up, DDEA has shown obvious advantages in elasticity, durability, moisture-absorbing and sweating ability, and antibacterial and odor-repellent effects, completely overturning the performance limitations of traditional insole materials. It is these excellent performance that makes DDEA a shining pearl in the field of modern sports insoles.
