| titleOfInvention | Method for stopping liquid phase reaction |
| abstract | An object of the present invention is to provide a method for stopping a reaction in which generation of impurities is suppressed in the production of an aromatic amine by hydrogenation reaction of a nitro group-containing aromatic compound in a liquid phase. In a liquid phase reaction in which an aromatic amine is produced by a hydrogenation reaction of a nitro group-containing aromatic compound, supply of hydrogen gas and a catalyst into a liquid phase reaction tank (reactor) 2 and liquid phase reaction tank 2, the supply of the nitro group-containing aromatic compound into the liquid phase reaction tank 2 and the supply of the catalyst are stopped while the discharge of the reaction solution 16 containing the catalyst from 2 is continued. When the concentration of the nitro group-containing aromatic compound reaches 30 ppm, or after that, the supply of hydrogen gas into the liquid phase reaction tank 2 is stopped.
