Epichlorohydrin is a colorless oily liquid with a pungent smell like ether and chloroform. It is flammable, volatile, toxic and anesthetic. Its relative density is 1.1812, melting point is -25.6℃, boiling point is 117.9℃, it is miscible with many organic solvents such as ethanol, propanol, ether, chloroform, acetone, trichloroethylene and carbon tetrachloride, it is easily soluble in benzene and slightly soluble in water. Since its molecular structure contains active chlorine atoms and epoxy groups, it is chemically active. When hydrolyzed, it first generates α-chloroglycerol and then glycerol. It can undergo a ring-opening reaction to generate propylene glycol and glycerol; it can react with alcohols and phenols to generate ethers; it can react with amines to generate glycidylamine; it can react with carboxylic acids to generate esters; it can self-polymerize; it can react with aldehydes (or ketones) to generate dioxolane.
