| Abstract: | Benzaldehyde glycol acetal was synthesized from benzaldehyde and glycol in the presence of H3PW12O40/PAn. The factors influencing the synthesis were discussed and the optimal conditions were found as follows:molar ratio of benzaldehyde to glycol is 1 : 1. 5, the quantity of catalyst is e-qual to 0. 8% of feed stock, and the reaction time is 1. 0h with cyclohaxance as water-carrying agent. The yield of benzaldehyde glycol acetal could be up to 85. 7%. |
