Abstract 1,191,935. Bis - (4 - Aminocyclohexyl) - alkanes. BADISCHE ANILIN- & SODA-FABRIK A.G. 15 Sept., 1967 [17 Sept., 1966], No. 42183/67. Heading C2C. Bis - (4 - Aminocyclohexyl) - alkanes are produced by reacting a bis-(4-hydroxycyclohexyl)- alkane with ammonia in the presence of hydrogen at elevated temperature and pressure in the liquid phase in the presence of a hydrogenation catalyst which contains cobalt, manganese and phosphoric acid. The preferred starting materials are those of Formula (I) in which R denotes an alkylene or alkylidene radical having 1-4 carbon atoms. Preferably the reaction is carried out at 150-200‹ C., a hydrogen partial pressure of 10-150 atm. gauge, and at a pressure of 400 atm. in the presence of a catalyst containing 99-90% by weight of cobalt and 1-10% by weight of manganese based on the total metal present at 0À5-10% of phosphoric acid based on the metal content. Examples are given of the production of bis-(4-amino-cyclohexyl)-propane-(2,2).
