Abstract:
The present invention relates to the technical field of chemical engineering and catalysis. Provided are an application of an ionic liquid in propylene glycol ether synthesis and a method for synthesizing a propylene glycol ether. The ionic liquid is a methyl carbonate ionic liquid, and is used as a catalyst for catalyzing propylene glycol ether synthesis. The method for synthesizing the propylene glycol ether comprises the following steps: placing propylene oxide and an alcohol within a reactor to contact a catalyst, and heating the mixture in an enclosed environment to 50-200° C. to obtain the propylene glycol ether, wherein the catalyst is a methyl carbonate ionic liquid. The method for synthesizing propylene glycol ether provided in the present invention is a green synthesis technique, and does not require special production equipment. The method has simple and easily controllable processes, and can be used in industrial production and applications.

Claim (Index 8):
The method for synthesizing propylene glycol ether according to  claim 6 , wherein the heating time is from 10 to 300 minutes.
