Abstract
The p-aminobenzenethiol was synthesized by using the p-nitrochlorobenzene as starting material.The sodium polysulfide was chosen as the reagent which was based on mechanism of nucleophilic substitution and reduction.The temperature of substitution was 90℃,reacting 5 h.The temperature of reduction was 150℃,reacting 3 h.The yield was 85.4% .Its appearance was white powder and melting point was 39.1℃ ~ 40.9℃.
