Abstract

A nickel catalytic system that makes it possible to obtain branched compounds from fatty substances by reacting simple olefins on polyunsaturated esters, which may or may not be conjugated, is described. The compounds that are obtained may be hydrogenated and used as lubricant bases or may be transformed according to known procedures into compounds of acid, alcohol, amine or amide type, used in varied applications.
