摘要：

The liquid phase benzoylation of benzene with benzoyl chloride (BOG) to benzophenone is catalyzed by various zeolites at 353 K. Zeolite H-beta is found to be more active than the other zeolites. The conversion of benzoyl chloride to benzophenone over H-beta increases significantly with increase in the reaction time, temperature, catalyst/BOC (wt/wt) and benzene/BOC (mole) ratios. The yield of benzophenone decreases with increase in SiO2/Al2O3 ratio and isomorphous substitution of Al- by Ga- and Fe- in zeolite H-Al-beta in the following order: Al- > Ga- > Fe-H-beta suggesting that high density of acidic centers along with strong acid sites are required for the reaction.
