The invention provides a method of preparing β-erythritol fatty acid monoester, including: subjecting a fatty acid and erythritol to esterification reaction in the presence of an acid catalyst, a water carrier and an optional phase transfer catalyst, wherein the molar ratio of the fatty acid to erythritol is 1:2 to 1:3, and the temperature of the esterification reaction is 80-100° C. In addition, the invention further provides a method of preparing 2,3-erythritol fatty acid diester, including: subjecting a fatty acid and erythritol to esterification reaction in the presence of an acid catalyst and a water carrier, wherein the molar ratio of the fatty acid to erythritol is 2:1 to 3:1, and the temperature of the esterification reaction is 120-160° C.
该发明提供了一种制备β-赤藓醇脂肪酸单酯的方法,包括:在酸催化剂、水载体和可选的相转移催化剂的存在下,将脂肪酸和赤藓醇进行酯化反应,其中脂肪酸与赤藓醇的摩尔比为1:2至1:3,酯化反应的温度为80-100°C。此外,该发明还提供了一种制备2,3-赤藓醇脂肪酸二酯的方法,包括:在酸催化剂和水载体的存在下,将脂肪酸和赤藓醇进行酯化反应,其中脂肪酸与赤藓醇的摩尔比为2:1至3:1,酯化反应的温度为120-160°C。
