Products Description of 2-Ethyl-2-(hydroxymethyl)-1,3-propanediol CAS#77-99-6
Trimethylolpropane (TMP for short) has the chemical name 2-ethyl-2-hydroxymethyl-1,3-propanediol, also known as trimethylol propane and 2,2-dihydroxymethylbutanol. It has three typical hydroxymethyl groups in its molecule, so it has the properties of a polyol similar to glycerol. It can react with organic acids to form monoesters or polyesters, react with aldehydes and ketones to form acetals and ketals, and react with diisocyanate to form carbamates, etc. It is a widely used chemical raw material and chemical product, mainly used in alkyd resins, polyurethanes, unsaturated resins, polyester resins, coatings and other fields. It can also be used to synthesize aviation lubricants, plasticizers, surfactants, wetting agents, explosives, printing inks, etc. It can also be directly used as a textile auxiliaries and heat stabilizers for PVC resins.
