Method for preparing nitroaniline by continuous convective ammoniation of nitrochlorobenzene |
| abstract |
The technical scheme discloses a method for preparing nitroaniline by continuous convection ammoniation of nitrochlorobenzene, which adopts a reaction kettle and a convection tower; Nitroaniline is synthesized with ammonia water for the first time in the reactor, the reaction temperature rises, and the density of this reaction system increases, so that both nitrochlorobenzene and the product float on the liquid level of the reaction mixture in the reactor. The technical problem solved by this technical solution is: how to improve the synthesis efficiency of nitroaniline. |
