ABSTRACT:
A zeolite catalyst, which can be used in a process for hydroxylating benzene to phenol, is treated with an aqueous solution containing ferric or ferrous ions, and is treated with an aqueous solution containing dithionate ions. The treated catalyst exhibits improved selectivity and stability in the benzene hydroxylation process.
