Abstract
Achievements of 3-aminobenzoic acid in organic chemistry and basic research on industrial production are manifold.Used as an intermediate for medicine and dye,in industrial production for the manufacture of azo dyes,medicine biodobenzene acid and bile acid filmo also it is an important raw material to create pressure-ian replication materials,especially in the synthesis of ketoprofen which is a anti-inflammatory analgesic drug.3-nitrobenzoic acid was synthesized from nitration reaction to use benzoic acid as row materials.Then through two reduction reactions of 3-aminobenzoic acid,including iron and metal palladium catalytic reduction of carbon.Compare two methods:in the diazotization of 3-nitrobenzoic acid,palladium-charcoal catalyst showed high catalytic activity and selectivity,increase the yield of the target product.
