METHOD OF SYNTHESIS OF EPICHLOROHYDRIN Russian patent published in 2003 - IPC

Abstract RU 2198882 C1

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
