Method for electrochemical synthesis of benzoic acid and salts thereof

The invention provides a method for electrochemical synthesis of benzoic acid and salts thereof, and belongs to the field of electrochemical organic synthesis and selective oxidation. According to the method, a microporous conductive film loaded with a bimetallic oxide catalyst is used as an anode, and benzoate is synthesized through electro-catalytic oxidation of benzyl alcohol in an alkaline electrolyte. According to the method, firstly, a Co or Ni-based bimetal loaded microporous conductive tubular membrane is used as an anode through hydrothermal and roasting, benzoate is synthesized through an electrocatalytic oxidation reaction in an alkaline electrolyte, and then benzoate is obtained through evaporative crystallization. On the basis, the high-purity benzoic acid solid powder is prepared by using strong acid to prepare weak acid and a recrystallization principle, and the method is short in reaction time, easy to control, efficient and high in selectivity, is a very green and efficient preparation method
