Neopentyl glycol, trimethylolpropane

Trimethylolpropane Complete Plant

Trimethylolpropane (abbreviated as TMP) is a white flake crystal. It is easily soluble in water, lower alcohols, glycerol, and N,N-dimethylformamide, partially soluble in acetone and ethyl acetate, and slightly soluble in carbon tetrachloride, ether, and chloroform. It is mainly used in the fields of alkyd resins, polyurethanes, unsaturated resins, polyester resins, coatings, etc. It can also be used for synthesizing aviation lubricants, printing inks, etc., and can also be used as textile auxiliaries and heat stabilizers for polyvinyl chloride resins. The synthesis method involves a condensation reaction between n-butyraldehyde and formaldehyde under alkaline conditions. The reaction solution is concentrated to remove salts, then decolorized and purified with ion exchange resins, and finally evaporated, cooled, and flaked with a thin-film evaporator to obtain the finished product. The product is mainly used in the fields of alkyd resins, polyurethanes, unsaturated resins, polyester resins, coatings, etc. It can also be used for synthesizing aviation lubricants, plasticizers, surfactants, wetting agents, explosives, printing inks, etc., and can also be used as textile auxiliaries and heat stabilizers for polyvinyl chloride resins.
