Trimethylolpropane (TMP for short), white flake crystal. It is easily soluble in water, low-carbon alcohol, glycerin, N,N-dimethylformamide, partially soluble in acetone and ethyl acetate, slightly soluble in carbon tetrachloride, ether and chloroform. It is mainly used in the fields of alkyd resin, polyurethane, unsaturated resin, polyester resin, coatings, etc., and can also be used in the synthesis of aviation lubricating oils, printing inks, etc., and can also be used as a textile additive and thermal stabilizer for polyvinyl chloride resin.
Trimethylolpropane is an important fine chemical product and is a chain extender commonly used in the resin industry. Its melting point is low and there are 3 hydroxymethyl groups in its molecular structure. It can react with organic acids to form monoesters or polyesters, react with aldehydes and ketones to form acetals and ketones, and react with diisocyanates to form carbamates, etc.
