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
The present invention relates to a kind of preparation method of stearic acid polyoxyethylene ether.
Background technology
Stearic acid polyoxyethylene is dirty good emulsifying and thickening property, can be used as the emulsifying agent of makeup or other paste products; There is flexibility and static resistance, for the synthesis of emulsifying agent and the finish of fibre finish.But its synthetic method is rare report.
Summary of the invention
Technical problem to be solved by this invention is: the preparation method that a kind of stearic acid polyoxyethylene ether is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of preparation method of stearic acid polyoxyethylene ether, take stearic acid and oxyethane as raw material, under the existence of Zinc oxide catalytic, carry out polyreaction and make, the ratio of weight and number of described stearic acid and oxyethane is 20-25:15-23, and the parts by weight of zinc oxide are 2-6; Polymeric reaction temperature is 150-160 degree Celsius, and the time is 2-5 hour.
The invention has the beneficial effects as follows: reaction conditions gentleness, low for equipment requirements, and yield is high, does not have impurity to generate, environmental friendliness.
