Description?

In organic synthesis, 1,1,3,3-tetramethylguanidine is used as a strong, non-nucleophilic base. 1,1,3,3-tetramethylguanidine is an efficient and selective catalyst for alcohol benzoylation.

Physical and chemical properties tetramethylguanidine is a colorless oily liquid, boiling point 160-162?, density 0.918, refractive index 1.4692, is a strong organic base, soluble in toluene, cyclohexanone, ethanol, etc., also Chemicalbook soluble in water, easily hydrolyzed to tetramethyl urea in alkaline aqueous solution, corrosive, generally packed in galvanized iron drums.

Applications?

NT CAT TMG can also be used as a catalyst for polyurethane foam and for even dyeing of nylon, wool and other proteins to improve the durability of wool, etc. It is mainly used in the synthesis of cefradine and other drugs.

Storage Information?

NEWTOP Chemical recommends that our catalysts be stored in a dry and cool area under appropriate ventilation conditions. Each container should be closed tightly to avoid contamination with moisture or other negative influences that could change the products’ performance in the end use. The optimum storage temperature is between 10 °C and 30° C. Lower and higher storage temperatures are not preferable and should be avoided.

Features and uses:

PC-37 is colorless or light yellow liquid at room temperature, soluble in water;

PC-37 is a low odor reactive catalyst for rigid packaging foam. Its structure contains active hydrogen, which can react with -NCO and combine into the system, so the smell of finished products is greatly reduced. NT CAT PC-37 can also be used for molding soft foam and polyether polyurethane soft block foam.

 

Storage Information:

Store in a cool and ventilated warehouse. Keep away from fire and heat. Protect from direct sunlight. Keep container sealed. It should be stored separately from oxidant and edible chemicals, and mixed storage is forbidden. Firefighting equipment of corresponding variety and quantity shall be provided.

 

Package:

190KG/Steel Drum
