  • Selective hydrogenation of aliphatic dinitriles to omega-aminonitriles in ammonia with supported, finely dispersed rhodium-containing catalyst
    Patent number: 4601859
    Abstract: A dinitrile is hydrogenated to an omega-aminonitrile with hydrogen with a supported highly dispersed rhodium catalyst and only ammonia present. The catalyst is prepared by hydrolyzing a rhodium(III) halide or nitrate with strong aqueous base at elevated temperatures, drying the supported rhodium hydroxide at elevated temperatures and intimately contacting with hydrogen the dried product with hydrogen at 260.degree.-360.degree. C. High conversions, selectivity to aminonitrile and long catalyst service times and catalyst recyclability are achieved in the absence of an aprotic solvent.
