Abstract
An imine compound is produced in high yield by reacting a benzophenone with ammonia in the presence of 0.01 to 100% by weight of an oxide of at least one of metals selected from the group consisting of metals of the second to fifth periods of Group III to V of the periodic Table, and iron as a catalyst at a reaction temperature of 150.degree. to 250.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 metal oxide can be readily recovered and reused without any influence of water formed by the reaction.
