Abstract
The invention relates to a process for catalytic hydrogenation of non-hormonal unsaturated plant steroids and unsaturated plant-based fatty acids and triglycerides thereof using a metal catalyst bound to a polymer support containing grafted groups. The invention also relates to regeneration of a used catalyst.
Claims12
A process for hydrogenating non-hormonal unsaturated plant steroids catalytically with hydrogen, wherein the catalyst is a transition metal catalyst selected from the group consisting of Ni, Pd, Pt, Rh, Ru and mixtures thereof, and is bound to a polymer support selected from the group consisting of polyolefin and halogenated polyolefin, and containing grafted groups selected from the group consisting of acrylic acid, polyacrylic acid, methacrylic acid, polymethacrylic acid, styrene and polystyrene groups;
- and wherein the steroids are hydrogenated in a solvent, and the hydrogenation is carried out at an overpressure of 0.5 to 10 bar, and a temperature varying from room temperature to about 200.degree. C.
