Products Description of 2-Ethyl-2-(hydroxymethyl)-1,3-propanediol CAS#77-99-6
Trimethylolpropane, commonly abbreviated as TMP, bears the chemical names 2-ethyl-2-hydroxymethyl-1,3-propanediol, trimethylolpropane, and 2,2-dihydroxymethylbutanol. Its molecule contains three characteristic hydroxymethyl groups, endowing it with polyol properties analogous to glycerol. It is capable of reacting with organic acids to form monoesters or polyesters, with aldehydes and ketones to produce acetals and ketals, and with diisocyanates to yield carbamates, among other reactions. As a widely utilized chemical raw material and product, it is primarily applied in alkyd resins, polyurethanes, unsaturated resins, polyester resins, coatings, and related fields. It can also be used to synthesize aviation lubricants, plasticizers, surfactants, wetting agents, explosives, printing inks, and more. Additionally, it serves directly as a textile auxiliary and a heat stabilizer for PVC resins.
