Abstract
Abstract Highly unsaturated oils of vegetable or animal origin are selectively hydenated to less highly unsaturated oils using a catalytic composition obtained by dissolving a compound of a metal selected from the IB, IV B to VII B or VIII groups in an unsaturated oil and then adding thereto an organic derivative or hydride of a metal from groups I A, II A, II B or III A, in the absence of a stabilizing solvent.

Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
121 words
In a process for selectively hydrogenating a polyunsaturated glyceridic oil of vegetable or animal origin, wherein hydrogen is reacted with said oil in contact with a catalyst obtained by reacting in a solvent: (a) at least one compound of a metal from groups I B, IV B, V B, VI B, VII B and VIII with (b) at least one reducing organic compound having at least one carbon metal bond or hydride of a metal from groups I A, II A, II B and III A, the molar ratio of the reducing compound to the metal compound being from 0.1 to 1 to 6:1, the improvement wherein said solvent consists essentially of a polyunsaturated glyceridic oil of vegetable or animal origin.
Claim 2
Dependent Claim
121 words
