Abstract

Benzaldehyde glycol acetal was synthesized from benzaldehyde and ethylene glycol in the present of(CePW_(12)O_(40)).The factors influencing the synthesis were discussed and the better conditions were found as follows: based on 0.1 mol benzaldehyde,the molar ratio of benzaldehyde to ethylene glycol is 1.0/1.7,the quantity of catalyst is equal to 1.0% of the feed stock,the amount of tulene 10 mL and the reaction time is 2.0 h.Under the above conditions its yield can reach over 79.5%.
