APPLICATION OF IONIC LIQUID IN PROPYLENE GLYCOL ETHER SYNTHESIS AND METHOD FOR SYNTHESIZING PROPYLENE GLYCOL ETHER

摘要

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.
