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

technical field [0001] The invention relates to a preparation method of polyoxyethylene stearate. Background technique [0002] Polyoxyethylene stearate has good emulsifying and thickening properties, and can be used as an emulsifier for cosmetics or other paste products; it has softness and antistatic properties, and is used as an emulsifier and oil for synthetic fiber finishing. However, its synthetic methods are rarely reported. Contents of the invention [0003] The technical problem to be solved by this invention is: provide a kind of preparation method of stearic acid polyoxyethylene ether. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: [0005] A kind of preparation method of stearic acid polyoxyethylene ether, take stearic acid and oxirane as raw material, carry out polymerization reaction under the existence of zinc oxide catalyst and make, the weight of described stearic a...
