METHOD OF SYNTHESIS OF EPICHLOROHYDRIN

摘要

FIELD: organic chemistry, chemical technology. SUBSTANCE: invention relates to method of synthesis of halogenolefin oxides by dehydrochlorination of halogen-containing alcohols and can be used in production of epichlorohydrin. Method of synthesis of epichlorohydrin involves dehydrochlorination reaction of glycerol dichlorohydrin with sodium hydroxide using anhydrous glycerol dichlorohydrin and alkali in concentration 25-30%. Process is carried out at temperature 55-77 C and under reduced pressure 0.6-0.7 atm. Invention provides decrease of sewage amount. EFFECT: improved method of synthesis. 1 dwg
