SELECTIVE HYDROGENATION OF FATS AND DERIVATES USING ZIEGLER-TYPE ORGANOMETALLIC CATALYSTS III - SELECTIVE HYDROGENATION OF SATURATED AND UNSATURATED FATTY-ACID NITRILES TO SATURATED AND UNSATURATED PRIMARY AND SECUNDARY AMINES

A tallow oil nitrile fraction with 66% oleonitrile and 27% stearonitrile was hydrogenated under use of homogeneous nickel- or cobalt-metallorganic catalysts from Ziegler-type with high selectivity to the corresponding saturated primary and secondary amines or under conservation of the double bond in the oleonitrile to unsaturated primary or secondary fatty amines. The realized selectivities were: 97% for stearylamine, 100% for oleylamine, 97% for distearylamine and 76% for dioleylamine.
