| Abstract: | In the paper, the synthesis on high quality p-nitrophenol reacting from p-nitrochlorobenzene was studied. The results demonstrated that the optimum reaction conditions were sodium hydroxide concentration was 10 %, reaction temperature was 165-170℃, molar ratio of sodium hydroxide and p-nitrochlorobenzene was 2.2：1, and reaction time was 4 h. The yield of p-nitrophenol can be as high as 96.5 %, and 4,4-dintitrodiphenyi ether which was impurities in the product can be lower than 10 ppm. |
