| titleOfInvention | A kind of method utilizing microreactor to prepare 2,4-dinitroaniline |
| abstract | The invention relates to the technical field of preparation of 2,4-dinitroaniline, in particular to a method for preparing 2,4-dinitroaniline by using a microreactor. The steps are: (1) preparing equipment, preparing a preheater, The microreactor and two chromatographic pumps; (2) connect the reaction equipment, connect the two chromatographic pumps to the preheater and the microreactor respectively, and then connect the preheater to the microreactor, and connect the preheater to the microreactor after the connection is completed; The microreactor is placed in a constant temperature oil bath; (3) the transport of the reaction material, the ammonia water is transported to the preheater at a preset flow rate, and the melted 2,4-dinitrochlorobenzene is transported to the microreactor at a preset flow rate. Mixed reaction with ammonia water in the reactor to obtain 2,4-dinitroaniline; (4) according to step (3), after the material reaction is completed, excess ammonia is re-made into ammonia water for reuse by the ammonia recovery device, and the reaction is The ammonia generated by the reaction of the produced ammonium chloride and potassium hydroxide continues to be reused, and the invention has the characteristics of high production efficiency, low energy consumption, economical and environmental protection, safety and reliability. |
