Abstract

The invention discloses a polyoxyethylene ether stearate preparation method. A polymerization reaction on raw materials comprising stearic acid and oxirane is carried out in the presence of a zinc oxide catalyst at a temperature of 150-160DEG C for 2-5h in order to obtain polyoxyethylene ether stearate, wherein a weight part ratio of stearic acid to oxirane is 20-25:15-23, and the weight part number of zinc oxide is 2-6. The method has the advantages of mild reaction conditions, low equipment requirements, high yield, no impurity generation and environmental protection.

Description
