Continuous process for recovery of glycide

摘要

Glycide is prepared by reacting allyl alcohol with hydrogen peroxide in the presence of a tungsten compound as a catalysts the excess allyl alcohol and the greatest part of the water distilled off, the sump mixture obtained in the distillation is split at 110 DEG -220 DEG C. and 5 to 60 torr in a thin layer evaporator into a volatile portion which is predominantly glycide, high boiling by products and the residual part of the water and a sump portion of glycerine, polyglycerine and catalysts. The volatile liquid portion is broken into glycide, water and high boiling byproducts at 5 to 60 torr in a distillation apparatus directly connected to the thin layer evaporator.
