US7586014: Process for the liquid phase selective hydroxylation of benzene

The invention provides an improved process for the liquid phase selective hydroxylation of benzene. The process provides a direct single-step selective liquid phase hydroxylation of benzene to phenol using environment-friendly green oxidant, hydrogen peroxide, and vanadyl pyrophosphate as the catalyst under mild reaction conditions. The process provides benzene conversion of 30-70% and selectivity for phenol of up to 100%.
