Abstract
The present application relates to a method for treating aromatic chlorides, and in particular to a catalytic hydrogenation dechlorination method for efficiently degrading aromatic chlorides. The method uses an amphiphilic C-TiO2 material as a carrier, and an amphiphilic supported bimetallic catalyst with Pd and Co as active components. The catalyst uses hydrogen as a hydrogen source and performs hydrogenation dechlorination reaction on aromatic chlorides in the presence of a basic proton absorber. The method has high efficiency, mild reaction conditions, easy operation control, and easy recovery of products and catalysts, and has good production and practical value.
