| titleOfInvention | A clean process for continuous synthesis of 2,6-dichloro-p-nitroaniline |
| abstract | A clean process for continuous synthesis of 2,6-dichloro-p-nitroaniline, the process is: using multi-stage series reaction kettles, continuously adding p-nitroaniline, hydrochloric acid and chlorine to the primary reaction kettle During the chlorination reaction, the chlorination reaction is carried out under stirring. Part of the material in the upper reactor is circulated in its own reactor through the pump, and part of it enters the next reactor to continue the chlorination reaction. The tail gas generated by the upper reactor enters the The chlorination reaction continues in the next-stage reactor, and part of the material in the last-stage reactor is circulated in its own reactor through the pump. After the reaction is completed, part of the material is continuously discharged and filtered, and the obtained filter cake is 2,6- For dichloro-p-nitroaniline products, the mother liquor obtained by filtering enters the mother liquor recovery tank, blows air into the mother liquor in the mother liquor recovery tank, and the blown out hydrogen chloride tail gas is reused, and when the mother liquor blows air to a certain acidity, it is pumped into the mother liquor storage tank, and the mother liquor The mother liquor in the storage tank replaces hydrochloric acid and circulates mechanically. |
