ABSTRACT:
In the catalytic reaction of cyclohexane or an alkylated cyclohexane with ammonia to produce aniline or an alkylated aniline, the presence of water is beneficial in increasing the amount of aromatic amines produced, or in reducing the amount of undesired by-products, or both. The amount of water is 1 to 70 mole percent based on the total amount of the cyclohexane reactant and water used. The catalysts used are exemplified by zinc oxide, titanium oxide, etc.; metal compounds such as vanadates, molybdates and titanates; and cadmium sulfide, zinc selenide and the like.
