STUDY ON SYNTHESIS OF PROPYLENE GLYCOL MONOETHYL ETHER WITH MAF SOLID BASE AS CATALYST

The synthetic process of propylene glycol monoethyl ether from propylene oxide and ethanol using solid base catalyst MAF was investigated. Under the reaction conditions of reaction temperature 120-130℃,amount of catalyst 0.50%-1.0%, and ethanol/PO molar ratio= (4-6):1, the conversion of propylene oxide is about 98%, the selectivity and yield of propylene glycol monoethyl ether is 92% and 90% respectively, and the selectivity of primary ether is 92%-93% in the product. The catalyst could be reused directly for many times.
