Abstract
Based on the 2-nitrobenzoic acid as raw material,sodium sulfide as reducing agent were transformed into anthranilic acid.Study the better process parameters of the reaction,the molar ratio of 2-nitrobenzoic acid,sodium sulfide is 1∶2.0,reaction time was 2.0 h,reaction temperature was 80℃.We can get the better process parameters of the reaction,which showed that the average yield and the purity of product could reach to 78% and 97% respectively.
