2- Method of Producing Benzoic Acid Via Selective Oxidation of Crude Acetophenone Including 2-Phenyl Propionaldehyde

摘要

The present invention relates to a method for producing benzoic acid through selective oxidation from crude acetophenone containing 2-phenyl propionaldehyde, wherein crude acetophenone containing 2-phenyl propionaldehyde is pre-separated at a high temperature, and then the acid is As a catalyst, benzoic acid can be efficiently produced in high yield by converting 2-phenyl propionaldehyde to acetophenone using benzoic acid and water as co-catalysts.
