Abstract
The invention relates to a novel one-step process for preparation of phenol by oxidation of benzene with hydrogen peroxide catalyzed by molecular sieves doped with copper ions. With proper solvent, a phenol yield around 15-35%, selectivity close to 100% and phenol/Cu TON around 100 could be achieved. These results show that the inventive process is of great economical value for further development in large scale production of phenol.
