| Abstract: | Based on the 2-nitrobenzoic acid as raw material, sodium suliide as reducing agent were transtormed into anthranlliC acid. Study the better process parameters of the reaction, the molar ratio of 2-nitrobenzoie 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. |
