WERKWIJZE VOOR HET HYDROGENEREN VAN MEERVOUDIG ONVERZADIGDE VETZUREN.

摘要

A process for the highly selective hydrogenation of polyunsaturated fatty acids and their triglycerides to the monounsaturated compounds using a homogenous Pd(II) catalyst in an ion-exchange resin and a process for improving the carrier properties for this and other reactions of ion-exchange resins are described. The resin's properties are improved by treatment with base or acid, without changing the number of active sites by more than 25% until the percentage of active sites readily accessible to large molecules is increased by at least 20%. In the hydrogenation process the Pd(II) is introduced into the salt-form of cation-exchange resins and into the hydroxyl or neutral form of anion-exchange resins.
