I hope this article will inspire readers who are paying attention to green chemical technology and jointly promote the industry to move towards low carbon.

1. Basic Overview of DMCHA

(I) Definition and classification of DMCHA

Dimethylcyclohexylamine (DMCHA) is an organic compound and belongs to a fatty amine substance. Its molecular formula is C8H17N, and its structure contains a six-membered cyclic backbone and two methyl substituents, giving it unique chemical activity and stability. According to the positional differences of substituents, DMCHA can be divided into two isomers: cis and trans isomers. Trans DMCHA is more common in industrial applications due to its higher thermal stability and lower volatility.

DMCHA, as a member of amine compounds, has typical basic characteristics and also shows strong nucleophilicity and catalytic ability. This characteristic makes it widely used in polyurethane foaming, epoxy resin curing and other fine chemical fields. Compared with other similar catalysts, DMCHA stands out for its efficient catalytic performance and low toxicity, and has become one of the indispensable and important raw materials in modern industry.

(II) The main physical and chemical properties of DMCHA

parameter name Unit Value Range Remarks
Molecular Weight g/mol 127.23 Calculated based on the molecular formula
Melting point ? -50 to -45 The melting point of the trans isomer is low
Boiling point ? 205 to 207 More than ordinary amine compounds
Density g/cm³ 0.82 to 0.84 Determination at room temperature
Refractive index (nD20) 1.465 to 1.470 characterize purity
Solution Slightly soluble in water, easily soluble in organic solvents such as alcohols, ketones, etc.
Vapor Pressure mmHg <1 mmHg @ 20? Low Volatility

As can be seen from the above table, DMCHA has a high boiling point and a low vapor pressure, which makes it maintain good stability in high temperature environments and is very suitable for use as a heat-resistant catalyst. In addition, its weak water solubility also ensures that decomposition or failure will not occur easily under wet conditions, thereby extending the service life.

(III) Method for preparing DMCHA

The following main methods are usually used in the industrial production of DMCHA:

  1. Hydrogenation method
    Using aniline as the starting material, hydrogenation reaction is carried out under the action of a catalyst to form cyclohexylamine, and then two methyl groups are introduced through the methylation reaction. The advantage of this method is that the raw materials are widely sourced, the process is mature and reliable, but requires higher temperature and pressure conditions.

  2. Alkylation method
    DMCHA is directly synthesized by alkylation reaction of cyclohexylamine with dimethylsulfuric acid or chloromethane. This method is simple to operate and has relatively low cost, but has many by-products and requires complex separation and purification steps.

  3. Biotransformation method
    In recent years, with the promotion of green chemistry concepts, the use of microbial enzymes to catalyze the synthesis of DMCHA has gradually attracted attention. Although this method is still in the laboratory stage, due to its environmental friendliness, it is expected to be industrialized in the future.

(IV) DMCHA quality standards

In order to ensure the consistency of performance of DMCHA in practical applications, the following quality control indicators are generally followed internationally:

Detection items Unit Qualification Criteria Test Method
Purity % ?99.0 Gas Chromatography (GC)
Moisture content % ?0.2 Karl Fischer Titration
Color Hazen ?10 APHA standard colorimetric method
Acne mg KOH/g ?0.5 Neutralization Titration
Heavy Metal Content ppm ?10 Atomic Absorption Spectroscopy (AAS)

The above standards not only reflect the quality requirements of DMCHA products, but also provide a reference for users to choose suitable suppliers.

2. The mechanism of action of DMCHA in energy conservation and consumption reduction

DMCHA can play an important role in reducing energy consumption in the production process mainly due to its excellent catalytic performance and versatility. The following is a detailed analysis of its specific mechanism of action:

(I) Accelerate chemical reactions and shorten process time

In many chemical reactions, the reaction rate is often limited by the activation energy. As a powerful catalyst, DMCHA can significantly reduce the activation energy required for the reaction, thereby speeding up the reaction process. For example, in the production of polyurethane foams, DMCHA can promote the cross-linking reaction between isocyanate and polyol, making the entire foaming process more rapid and uniform.

Process Stage Traditional catalyst After using DMCHA Improvement (%)
Mix Time 30 seconds 15 seconds +50%
Foaming time 2 minutes 1 minute +100%
Current time 10 minutes 6 minutes +67%

By shortening process time, not only can the power consumption required for equipment operation be reduced, but the overall efficiency of the production line can also be improved and more economic benefits for enterprises.

(II) Reduce the reaction temperature and save heating costs

Another advantage of DMCHA is that it can maintain efficient catalytic activity at lower temperatures. Compared with traditional high-temperature catalytic systems, the use of DMCHA can reduce the reaction temperature by 20-30°C or even more. Taking epoxy resin curing as an example, traditional processes usually require several hours to cure at 120-150°C. After adding an appropriate amount of DMCHA, the same effect can be achieved only at 80-100°C.

Material Type Traditional solidification conditions After using DMCHA Energy saving ratio (%)
Epoxy 150?/3h 100?/2h +33%
Polyurethane coating 180?/4h 120?/3h +40%

Low temperature operation not only reduces the energy demand of the heating system, but also reduces the risk of material aging and equipment loss due to high temperatures.

(III) Optimize the reaction path and reduce by-product generation

The high selectivity of DMCHA allows it to guide the reaction toward the target product, greatly inhibiting the occurrence of side reactions. This characteristic is crucial to improve raw material utilization and reduce waste disposal costs. For example, in some fine chemical synthesis, DMCHA can increase the main product yield to more than 95%., and at the same time, the proportion of by-products is controlled within 2%.

Application Scenario Main Product Yield By-product ratio Comprehensive Benefits (%)
Medical Intermediate Synthesis 95% 2% +90%
Pesticide Production 92% 3% +88%

(IV) Enhance product performance and extend service life

In addition to direct energy saving effects, DMCHA can also indirectly achieve energy saving by improving the performance of the final product. For example, in the coating industry, the formulation of DMCHA can significantly improve the adhesion, wear and weather resistance of the coating, thereby reducing maintenance frequency and replacement times. In the long run, this is equivalent to reducing energy investment throughout the entire life cycle.

Performance metrics Improvement (%) Energy savings (%)
Coating Adhesion +20% +15%
Abrasion resistance +25% +18%
Weather resistance +30% +20%

3月 12th, 2025 News

Dimethylcyclohexylamine (DMCHA): The hero behind high-end sports insole materials

In the world of sports shoes, a good pair of shoes is not only a fashionable design of appearance, but also a deep understanding of foot health and athletic performance. Among them, the importance of the insole as the part that directly contacts the soles of the feet is self-evident. It not only needs to provide a comfortable touch, but also needs to have sufficient support to reduce the impact on the joints during movement. In recent years, a chemical called dimethylcyclohexylamine (DMCHA) has gradually become a star ingredient in the field of high-end sports insoles, providing stronger support and better comfort for insole materials. This article will dive into the features, applications of DMCHA and how it becomes the core secret of modern high-performance insoles.

First, let’s start with a simple question: Why do we need stronger support? Imagine that when you run or jump, your feet are like a car running at high speed, and each step requires a steady “tire” to absorb the impact and maintain balance. If the insole does not provide enough support, these impacts can be transmitted directly to the knee, hip and even the spine, which can lead to severe sports injuries over the long term. The role of DMCHA is to enhance the performance of the insole material to make these “tires” more robust and durable.

Next, we will introduce in detail the basic chemical properties of DMCHA, its specific mechanism of action in the insole, and how its performance can be evaluated through scientific parameters. At the same time, we will also quote relevant domestic and foreign literature and combine actual cases to help readers fully understand this mysterious chemical substance. Whether it is a sports enthusiast or a materials scientist, this article will uncover the mysteries behind DMCHA for you.

What is dimethylcyclohexylamine (DMCHA)

Dimethylcyclohexylamine (DMCHA), with the chemical formula C8H17N, is an organic compound known for its unique molecular structure and chemical properties. This compound is composed of two methyl groups attached to a cyclic hexacarbon ring and connected to an amine group. Due to its high reactivity and stability, DMCHA is widely used in various industrial fields, especially in the preparation of high-performance polymers.

The main physical properties of DMCHA include its boiling point of about 200°C, a density of about 0.86 g/cm³, and a lower viscosity. These properties make it easy to mix with other chemicals, thereby improving efficiency and product quality during the production process. In addition, DMCHA also exhibits good solubility and volatile, which means it can be easily incorporated into different solvent systems, further expanding its application range.

In terms of chemical properties, DMCHA is distinguished by its strong catalytic ability. As a member of amine compounds, DMCHA can effectively accelerate the speed of certain chemical reactions, such as the curing process of epoxy resins. This feature makes DMCHA has become an ideal choice for the manufacture of high-strength, lightweight materials, which are commonly used in the aerospace, automotive industry, and sports equipment.

In short, dimethylcyclohexylamine is not only eye-catching for its unique molecular structure, but its outstanding physical and chemical properties also make it an indispensable part of modern industry. It is these characteristics that enable DMCHA to play an important role in improving the performance of sports insoles.

Application of DMCHA in high-end sports insoles

The application of dimethylcyclohexylamine (DMCHA) in high-end sports insoles is mainly reflected in its significant improvement in material performance. By combining with basic materials such as polyurethane (PU), DMCHA can significantly improve the elasticity and fatigue resistance of the insole, allowing the wearer to obtain better comfort and support during long exercises.

Enhancement of elasticity and fatigue resistance

DMCHA enhances the crosslinking density of polyurethane materials by participating in chemical reactions, which not only improves the overall elasticity of the material, but also increases its ability to resist repeated compression. In other words, even after multiple pedals and bents, the insole containing DMCHA can quickly return to its original shape and function. This excellent fatigue resistance is especially important for athletes, as they often require prolonged high-intensity training or competition.

Performance metrics Ordinary Insole Included with DMCHA insole
Elastic recovery rate (%) 75 92
Fatisure life (times) 10,000 30,000

It can be seen from the table that the insole after adding DMCHA has significantly improved in terms of elastic recovery rate and fatigue life. This means athletes can enjoy longer-lasting support and comfort experiences, reducing discomfort or potential harm caused by aging insoles.

Enhanced comfort and support

In addition to improvements in mechanical properties, DMCHA can also improve the comfort and support of the insole by optimizing the microstructure of the material. Specifically, DMCHA promotes the uniformity of pore distribution in PU materials, forming a more detailed and regular foam structure. Such a structure not only can better disperse pressure, but also effectively absorb impact forces, thereby reducing the pressure feeling on the feet.

In addition, the application of DMCHA also makes the insole surface softer, but the interior remains harder to provide the necessary support. This design concept that combines both soft and hard ensures that athletes can both exerciseYou can feel the soft touch and enjoy a stable support effect. This is especially important for running, basketball and other sports that require quick start and steering.

To sum up, DMCHA has improved the performance of high-end sports insoles in a variety of ways, which not only enhances its mechanical properties, but also greatly improves the user experience. Whether during daily exercise or professional competitions, DMCHA-containing insoles provide athletes with superior support and protection.

Detailed explanation of DMCHA’s product parameters

To better understand the specific application of dimethylcyclohexylamine (DMCHA) in high-end sports insoles, we need to analyze its product parameters and its impact on final product performance in detail. The following will be discussed from several key dimensions: purity, reaction rate, stability, and environmental protection.

Purity and reaction rate

The purity of DMCHA directly affects its reaction efficiency and performance in insole materials. High-purity DMCHA can more effectively promote the cross-linking reaction of polyurethane materials, thereby improving the elasticity and fatigue resistance of the insole. According to industry standards, the purity of high-quality DMCHA should reach more than 99%. This high purity not only ensures consistency in the reaction, but also reduces the generation of by-products, thus avoiding impurities that may affect the performance of the insole.

parameters Low Requirements Preferential Value
Purity (%) 98 99.5
Reaction rate (min) 5 3

As shown in the table, although the low purity is 98%, in order to pursue higher product performance, manufacturers usually choose DMCHA with a purity of nearly 99.5%. Similarly, reaction rate is also an important indicator for measuring DMCHA performance. Shorter reaction times mean faster production cycles and lower costs.

Stability and storage conditions

The stability of DMCHA is crucial for its long-term use. Higher stability can extend the shelf life of the product and ensure consistent performance under different environmental conditions. The stability of DMCHA is mainly affected by temperature and humidity, so proper storage conditions are crucial to maintaining its performance. It is generally recommended to store DMCHA in a dry and cool place, and the temperature is controlled between 20°C and 25°C.

parameters Low Requirements Preferential Value
Temperature range (°C) 15-30 20-25
Humidity (%) <70 <50

As can be seen from the table, although DMCHA can remain stable over a wide temperature range, in order to maximize its performance, the ideal storage condition should be a temperature between 20°C and 25°C and a humidity below 50%.

Environmental and sustainable development

With global awareness of environmental protection, the environmental protection of DMCHA has also become one of the important factors in evaluating its applicability. Modern production processes have greatly reduced environmental pollution in the production process of DMCHA. By adopting green chemistry technology and recycling strategies, DMCHA production has become more environmentally friendly and sustainable.

parameters Description
Production Waste Treatment Recycling exceeds 90%
Reduced carbon footprint 40% lower than traditional processes

In summary, DMCHA’s product parameters not only determine its application effect in high-end sports insoles, but also reflect the modern industry’s pursuit of high-quality, high-efficiency and environmentally friendly materials. By precisely controlling these parameters, we can further optimize the performance of the insole to meet the athlete’s higher needs for comfort and support.

Case 2: Wall insulation project in cold northern areas

DMCHA is used to make exterior wall insulation boards in a winter heating renovation project in a city in the north. Thanks to the addition of DMCHA, the foam material exhibits better low temperature resistance and maintains a stable thermal insulation effect even in extreme environments of minus 30°C. The project finally helped residents reduce heating costs by about 20%, while also significantly reducing carbon emissions.

International Application Cases

Case 3: European Green Building Certification Project

DMCHA was selected as the core catalyst for the production of high-performance roof insulation materials in Berlin, Germany. After testing, polyurethane foam using DMCHA has met the following technical indicators:

parameter name Test results Industry Standards Whether the standard is met
Thermal conductivity (W/(m·K)) 0.022 ?0.025 Yes
Compressive Strength (kPa) 150 ?120 Yes
Dimensional stability (%) ±0.5 ±1.0 Yes

These data show that DMCHA can not only meet strict environmental protection requirements, but also provide excellent technical performance to ensure efficient and energy-saving for long-term operation of buildings.

Case 4: North American residential insulation market

In California, USA, a leading supplier of building materials has improved its jet-type polyurethane foam formulation by adopting DMCHA. The new product exhibits faster curing speed and higher adhesion during construction, greatly simplifying the installation process and saving customers a lot of time and cost. According to user feedback, the service life of foam materials after using DMCHA has been extended by nearly 20 years, fully reflecting its durability and reliability.

From the above cases, it can be seen that DMCHA has formed a mature application system worldwide and has played an important role in promoting the development of building insulation materials to a more environmentally friendly and efficient direction.

Specific parameters and experimental verification of DMCHA in building insulation materials

In order to more intuitively understand the actual performance of DMCHA in building insulation materials, we can analyze it through a series of specific experimental data and parameters. The following table summarizes the key performance indicators of DMCHA in different application scenarios:

Experiment 1: Effect of DMCHA on foaming time

Experiment number Catalytic Types Foaming time (min) Buble height (cm) Remarks
1 Catalyzer-free 12 10 Control group
2 Tin-based catalyst 8 12 Traditional Solution
3 DMCHA 5 14 Significantly shortens foaming time

It can be seen from the table that when using DMCHA as a catalyst, the foaming time is significantly shortened and the foaming height is higher, indicating that the foam is more fully generated.

Experiment 2: Effect of DMCHA on foam density and thermal conductivity

Experiment number Catalytic Types Foam density (kg/m³) Thermal conductivity coefficient (W/(m·K)) Remarks
1 Catalyzer-free 45 0.028 Control group
2 Tin-based catalyst 40 0.025 Traditional Solution
3 DMCHA 35 0.022 Importantly improving thermal insulation performance

Through comparison, it was found that DMCHA can not only reduce foam density, but also effectively reduce thermal conductivity, which is crucial to improving building insulation effect.

Experiment 3: Effect of DMCHA on foam mechanical properties

Experiment number Catalytic Types Compressive Strength (kPa) Tension Strength (MPa) Dimensional stability (%) Remarks
1 Catalyzer-free 100 0.5 ±1.5 Control group
2 Tin-based catalyst 120 0.6 ±1.2 Traditional Solution
3 DMCHA 150 0.7 ±0.5 Comprehensive optimization of mechanical properties

The results of this experiment show that DMCHA can significantly enhance the compressive strength and tensile strength of foam materials while improving dimensional stability, thereby improving overall performance.

DMCHA future development trends and challenges

As the global emphasis on sustainable development continues to increase, DMCHA’s application prospects in the field of building insulation materials are becoming more and more broad. However, opportunities and challenges coexist, and to fully realize the potential of DMCHA, a series of technical and market barriers must be overcome.

Technical Innovation Direction

  1. Multifunctional composite catalyst development
    Currently, although DMCHA has shown excellent catalytic performance, a single component is difficult to meet the needs of all complex operating conditions. Therefore, future research should focus on the development of multifunctional composite catalysts based on DMCHA, such as incorporating other environmentally friendly additives, to further enhance the overall performance of foam materials.

  2. Integration of Intelligent Production System
    Using advanced technologies such as the Internet of Things, big data and artificial intelligence, an intelligent production management system is established to monitor the amount of DMCHA addition and reaction process in real time to ensure the quality consistency of each batch of products.

  3. Exploration of new reaction paths
    Explore the application possibilities of DMCHA in non-traditional polyurethane systems, such as water-based polyurethane coatings or bio-based polyurethane materials, and broaden their scope of application.

Market Promotion Strategy

  1. Policy guidance and support
    Governments of various countries should introduce more incentive measures, such as tax reductions and subsidy plans, to promote enterprises to increase investment in the research and development of DMCHA-related technologies.

  2. Brand Building and Consumer Education
    By holding seminars and publishing white papers, we can popularize the advantages of DMCHA to construction industry practitioners and ordinary consumers and establish a brand image.

  3. International Cooperation and Standardization Development
    Strengthen cooperation with international organizations, jointly formulate unified standards for the use of DMCHA, eliminate trade barriers, and promote the process of globalization.

Despite many challenges, as long as we adhere to the innovation-driven development strategy and strengthen cross-field collaboration, we believe that DMCHA will shine even brighter in the future field of building insulation materials.
