Beschreibung
Zusammenfassung:	The invention relates to a preparation method of fatty acid polyethylene glycol ester, and mainly solves the problem of high chromaticity of a product obtained by the existing preparation method of the fatty acid polyethylene glycol ester. The preparation method of fatty acid polyethylene glycol ester comprises the following steps: performing a first esterification reaction: in the presence of a reaction aid containing an acid catalyst, performing the first esterification reaction on a first esterification raw material mixture to obtain a first esterification product mixture, wherein the first esterification raw material mixture comprises polyethylene glycol and a first part of raw material fatty acid; and performing a second esterification reaction: carrying out second esterification reaction on asecond esterification raw material mixture to obtain the fatty acid polyethylene glycol ester product, wherein the second esterification raw material mixture comprises the first esterification product mixture and a
