| 2,4-Dinitroaniline Usage And Synthesis | |
| chemical properties | Yellow crystals. Slightly soluble in ethanol, insoluble in water, soluble in acid solution. |
| use | It is used in the manufacture of azo dyes and disperse dyes, as well as toners for printing inks and preparation of preservatives, etc. |
| use | This product is the intermediate of disperse dyes, neutral dyes, sulfur dyes and organic pigments. It is used to produce dyes such as sulphur dark blue 3R, disperse red B and disperse violet 2R. It is also used in other organic synthesis, the production of pesticide dinitrate powder, etc., as well as the toner of printing ink and the preparation of preservatives. |
| production method | From 2,4-dinitrochlorobenzene pressure ammonolysis derived. Add 15kg of pulling powder (sodium 1,2-dibutylnaphthalene-6-sulfonate), 300kg of 2,4-dinitrochlorobenzene, 1350L of ammonia water (containing 150kg of ammonia) into the ammonolysis reaction pot, heat it for 1 hour The temperature was raised to about 80°C, and the heating was stopped. The reaction temperature is controlled to be 108-110° C. and the pressure to be 0.35-0.4MPa. The pressure was released after 4 hours of incubation reaction. The released ammonia gas is absorbed and reused with water. The reaction solution was cooled to below 35°C and filtered, and the filter cake was washed with cold water until it was nearly neutral to obtain the finished product. Yield 90-95%. |
