Chemical Properties
Epichlorohydrin is a colorless oily liquid with irritating odor such as acid and chloroform, flammable, volatile, toxic and narcotic. Relative density 1.1812, melting point -25.6℃, boiling point 117.9℃, miscible with many organic solvents such as ethanol, propanol, acetaldehyde, chloroform, acetone, trichloroethylene and carbon tetrachloride, easily soluble in benzene, slightly soluble in water , Because the molecular structure contains active chlorine atoms and epoxy groups, it is chemically active. When hydrolyzed, a-chloroglycerol is generated first, and then glycerol is generated. It can generate propylene glycol and glycerol; react with alcohol and phenol to generate ether; react with amines to generate glycidyl amine; react with carboxylic acid to generate ester; can self-polymerize; react with aldehyde (or ketone) ) reaction can generate dioxane.
The main use of epichlorohydrin
Epichlorohydrin is mainly used in the preparation of glycerol, epoxy resin, chlorohydrin rubber, polyacid polyol, and is an important raw material for the production of glycerol and glycidol derivatives. , intermediates of synthetic glycerol and other chemical products. Organic solvent (solvent for resin, gum, cellulose acid, etc.); also used as plasticizer, surfactant, etc.
