Method of Producing Benzoic Acid by Selective Oxidation of Mixture Comprising Acetophenone

摘要

The present invention relates to a process for the selective oxidation of acetophenone in the presence of an acetic acid solvent and a manganese salt catalyst to produce benzoic acid, wherein an acetophenone mixture obtained by mixing a byproduct such as dipropylene glycol or tripropylene glycol Thereby yielding benzoic acid in a high yield by an economical method, and then partially recovering the produced benzoic acid to produce benzoic acid more efficiently.
