The invention concerns the preparation of glycerides in which glycidol is reacted with a fatty acid, first in the form of the anhydride to produce the corresponding epoxy glyceride or glycidol ester, at the same time liberating free fatty acid from the anhydride and thereafter continuing reaction, this time between the liberated free fatty acid or another acid, in the presence of an acylation catalyst under the influence of which the oxirane ring is ruptured and diglycerides produced. These may be used in the preparation of svnthetic fats.
本发明涉及甘油酯的制备,其中缩水甘油首先以酸酐的形式与脂肪酸反应,生成相应的环氧甘油酯或缩水甘油酯,同时从酸酐中释放出游离脂肪酸,然后继续反应,这次是在酰化催化剂的存在下,在释放出的游离脂肪酸或另一种酸之间进行反应,在催化剂的作用下,环氧乙烷环破裂,生成二甘油酯。 这些可用于制备合成脂肪。
