LIANG Hong-dong (School of Chemical Engineering, Guangdong College of Petrochemical Technology, Maoming 525000, China)

Abstract：Propylene glycol ether acetate was synthesized using ion exchange resin as catalyst. The influence of synthetic conditions such as the molar ratio of ether and acid, the dosage of catalyst, reaction time and the dosage of water carrying on yield was investigated. The results showed: molar ratio of propylene glycol ether to acetic acid was 1:1.3, the dosage of catalyst was 5%, the dosage of water carrying was 20%, reaction time was 5 h, The yield of propylene glycol ether acetate was75.3%. And the catalyst can be reused for one to two times.

Key words：ion exchange resin; catalytic synthesis; propylene glycol ether acetate
