One-step synthesis of propylene glycol monomethyl ether from propylene

Etherification between propylene oxitle and methanol with urea-manufattured solid hydrotalicites catalyst was researched．The influences of reaction temperature,pressure and time．the mol ratio of materials．and the calalyst amount on the conversion of propylene oxide and the selectivity of Ihe propylene glycol monomethyl ether were discused

Based on experiments, the formulation and preparation process for synthesis of propylene glycol monomethyl ether with novel alkaline catalyst are determined.

A separation technology for propylene epoxidation product - mixture of water,propanediol and 1,2-propyleneglycol-1-monomethyl ether was developed.

The influences on the yield of product of mole ratio of acetic acid to 1,2-propyleneglycol-1-monomethyl ether,reaction time,reaction temperature,and quantity of catalysts were i nvestigated.
