ABSTRACT:
An imine compound is produced by reacting a benzophenone with ammonia in the presence of 0.01 to 10% by weight of a carboxylic acid as a catalyst at a reaction temperature of 50.degree. to 350.degree. C on the basis of benzophenone. Ammonia is fed to the reaction system continuously under a pressure of 2 to 15 atmospheres. A solvent may be used for the reaction. The catalyst carboxylic acid can be readily recovered and reused without any influence of water formed by the reaction and brings about no problem of corrosion to reactor apparatus.
