White flaky crystals. Boiling point 295 ℃. Melting point 58.8 ℃. Relative density is 1.0889. Flash point (open cup) 180 ℃. The ignition point is 193 ℃. Melting heat 183.4kj/mol. The combustion heat is 3615kj/mol. Easily soluble in water, low-carbon alcohols, glycerol, N, N-dimethylformamide, partially soluble in acetone and ethyl acetate, slightly soluble in carbon tetrachloride, ether, and chloroform, but insoluble in aliphatic hydrocarbons, aromatic hydrocarbons, and chlorinated hydrocarbons. Its hygroscopicity is about 50% of glycerol.
It is widely used in the production of polyester and polyurethane foam plastics, as well as in the manufacture of alkyd coatings, synthetic lubricants, plasticizers, surfactants, rosin esters and explosives. It can also be directly used as a textile additive and a heat stabilizer for PVC resin.
