摘要:
Mono-unsaturated fatty acids or their derivates are produced by hydrogenating poly-unsaturated fatty acids or their derivates at 0 to 150 °C, in a pressure range from 800 to 1500 hPa, with hydrogen and in the presence of a catalyst system that contains: a) a palladium salt and b) a carbonic acid ester, as well as, if necessary, c) a base for neutralizing the acids formed during the reduction of the palladium salt, d) water and/or a water-immiscible, inert solvent.
