  Process for producing glyceryl ether

  摘要：

  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清洁剂。该方法包括在酸催化剂的存在下，使醇与α-环氧卤代醇反应，将反应混合物经环闭合转化为相应的环氧醚，然后水解环氧醚，其中：(a)水解在存在强碱性化合物和弱酸性化合物形成的盐的情况下，在140至230°C下进行，或者(b)水解后的反应混合物在存在强碱性化合物和弱酸性化合物形成的盐的情况下，在100至230°C下加热。

Other solvents may be present. Some of the said principal solvents are novel compounds and/or novel mixtures. Premixes of the fabric softening actives, the principal solvents, and, optionally, other solvents are useful in the preparation of complete formulations by obviating/limiting the need for heating.
