Abstract:
The present invention provides an improved process for the selective hydroxylation of benzene. The process provides a direct single step selective vapor phase hydroxylation of benzene to phenol using molecular oxygen (air) over Cu—Cr oxide catalysts. The process provides benzene conversion of 10 to 45% and selectivity for phenol up to 100%.
