description The invention relates to a synthesis method of fatty acid macrogol ester. The invention mainly solves the problem of high chromaticity of a product obtained by an existing synthesis method of fatty acid macrogol ester. The synthesis method of fatty acid macrogol ester comprises the following step: in the presence of an acid catalyst and other reaction assistants, subjecting polyethylene glycol and a raw material fatty acid to an esterification reaction to obtain the fatty acid polyethylene glycol ester, wherein the other reaction assistants comprise at least one selected from hypophosphorous acid compounds and stannous fatty acid. Thus, the above technical problem is well solved, and the method can be used for producing the fatty acid polyethylene glycol ester. 本发明涉及脂肪酸聚乙二醇酯的合成方法，主要解决脂肪酸聚乙二醇酯现有合成方法得到的产品色度高的问题，通过采用脂肪酸聚乙二醇酯的合成方法，包括在酸性催化剂和其他反应助剂存在下，聚乙二醇与原料脂肪酸发生酯化反应得到脂肪酸聚乙二醇酯，所述其它反应助剂包括选自次磷酸化合物和脂肪酸亚锡中的至少一种的技术方案，较好地解决了该技术问题，可用于脂肪酸聚乙二醇酯的生产中。
