Chemical name: 2-ethyl-2-hydroxymethyl-1,3-propanediol

Structural formula: CH3CH2C(CH2OH)3

Physical and Chemical properties:It is white crystal under ordinary temperature, the boiling point is 295℃ under ordinary pressure, Melting point is 58-59℃, Density of relativeity is 1.1758(20℃). Easy soluble in acetone, soluble in carbon tetrachloride, chloroform and ether. Insoluble in fatty hydrocarbon and aromatic hydrocarbon. stronger hygroscopic. There are three hydroxymethyls on the a position of TMP molecule, it possesses the following excellent properties: it can improve solidity, corrosion-resistant, sealing, and possesses good stability to water-decomposing, heat-decomposing and oxidation. Three hydroxyls have same reaction energy and so on.

Use:The use is wide. It is mainly used to producing Alkyd resin, Polyurethane and so on. In addition, it is raw material of synthetic lubricating oil, plasticizer, surface active agent, explosive and other fine chemicals.
