Title: Production of nitroaniline
Inventor: HORIKAWA YASUHIKO
IPC: C07C209/00
Filed: 1981-02-13
Abstract: PURPOSE: Nitrochlorbenzene is introduced with pressure into an ammonia solution which is kept at a prescribed temperature under pressure to prevent rapid and violent reaction and to produce the high-quality titled compound with reduced side-reactions safely with no danger of explosion.  
     CONSTITUTION: Nitrochlorobenzene of the formula (X is H, Cl, NO 2 ) is aminated with an ammonia solution to give nitroaniline where the reaction is effected by gradually introducing the compound of the formula with pressure into an ammonia solution kept at 100W200°C. The reaction system is under pressure, when it is kept at the prescribed temperature. The concentration of the ammonia solution is appropriately 5W40%. Going out of the above upper and lower limits of the temperature and concentration undesirably causes formation of by-products and retardation of the reaction.
