    • A process for producing a glyceryl ether which contains a markedly small amount of organohalogen compounds and therefore can be used even for cosmetics and body detergents. The process comprises reacting an alcohol with an &agr;-epihalohydrin in the presence of an acid catalyst, subjecting the reaction mixture to ring closure to convert it into the corresponding glycidyl ether and then hydrolyzing the glycidyl ether, wherein: (a) the hydrolysis is effected at 140 to 230° C. in the presence of a salt formed from a strongly basic compound and a weakly acidic compound, or (b) the reaction mixture after the hydrolysis is heated at 100 to 230° C. in the presence of a salt formed from a strongly basic compound and a weakly acidic compound.
    • 一种生产含有显着少量有机卤素化合物的甘油醚的方法,因此甚至可用于化妆品和身体洗涤剂。 该方法包括在酸催化剂存在下使醇与α-表卤醇反应,使反应混合物闭环以将其转化为相应的缩水甘油醚,然后水解缩水甘油醚,其中:(a)进行水解 在由强碱性化合物和弱酸性化合物形成的盐的存在下,在140〜230℃下,或(b)将水解后的反应混合物在盐酸存在下在100〜230℃下加热 由强碱性化合物和弱酸性化合物形成。
