- 4-Nitro-o-phenylenediamine Chemical properties: dark red needle-like crystals. Melting point is 201℃, soluble in ethanol, acetone and hydrochloric acid solution, but hardly soluble in water.
- 4-Nitro-o-phenylenediamine production method: Heat a mixture of 23.8g of 2,4-dinitroaniline, 240ml of 95% ethanol and 120ml of concentrated ammonia to 45°C, and pass hydrogen sulfide gas into it under stirring, and maintain the reaction at 45-55°C. . After the reaction was completed in the Chemicalbook, cooled, 4-nitro o-phenylenediamine was precipitated. The crude product obtained by filtration is dissolved in hydrochloric acid, added with activated carbon for decolorization, filtered while hot, and the filtrate is neutralized with concentrated ammonia, filtered, washed with water, and dried to obtain the finished product with a yield of 52-58%.
