A novel single step selective synthesis of 4-hydroxybenzophenone (4-HBP) using zeolite H-beta

The single step selective synthesis of 4-hydroxybenzophenone (4-HBP/2-HBP = 2.1, selectivity for 4-HBP among 2- and 4-HBP = 67.7 wt%) at 95.3 wt% conversion level of benzoic anhydride has been investigated for the first time by the benzoylation of phenol using benzoic anhydride as benzoylating agent...

Description
Summary:The single step selective synthesis of 4-hydroxybenzophenone (4-HBP/2-HBP = 2.1, selectivity for 4-HBP among 2- and 4-HBP = 67.7 wt%) at 95.3 wt% conversion level of benzoic anhydride has been investigated for the first time by the benzoylation of phenol using benzoic anhydride as benzoylating agent and zeolite H-beta as catalyst at 493 K in a Parr autoclave at autogenous pressure.
