Fatty acid ester derivatives and a process for their production from unsaturated fatty acids are disclosed. The process comprises:
a) reacting an unsaturated fatty acid or an ester thereof having one or more sites of unsaturation, with an epoxidation reagent to form a fatty acid epoxide wherein at least one of the sites of unsaturation of the fatty acid or fatty acid ester is converted to an oxirane ring; and
b) reacting the fatty acid epoxide produced in a) with a carboxylic acid to form a hydroxy fatty acid ester derivative wherein the oxirane ring is opened and converted to a hydroxy ester comprising a hydroxyl group at one carbon of the opened oxirane ring and an ester of the carboxylic acid at the other carbon of the opened oxirane ring.
本发明公开了脂肪酸酯衍生物及其从不饱和脂肪酸中生产的方法。该方法包括:a)将具有一个或多个不饱和位点的不饱和脂肪酸或其酯与环氧化试剂反应,形成脂肪酸环氧化物,其中脂肪酸或脂肪酸酯的至少一个不饱和位点被转化为环氧环;b)将步骤a)中产生的脂肪酸环氧化物与羧酸反应,形成羟基脂肪酸酯衍生物,其中环氧环被打开并转化为羟基酯,包括在打开的环氧环的一个碳上的羟基和在打开的环氧环的另一个碳上的羧酸酯。
