ABSTRACT:
A process for hydroxylating benzene under catalytic distillation conditions to produce hydroxylated products such as phenol is provided. The process provides for direct hydroxylation of liquid phase benzene with an oxidant and a zeolite catalyst under conditions effective to prevent coke formation on the catalyst.
