Abstract
To obtain branched compounds from fatty substances, simple olefins are reacted on polyunsaturated esters, which may or may not be conjugated, in the presence of an iron catalytic system, whereby the products that are obtained, primarily mono-addition compounds, can be hydrogenated and transformed into various compounds that can be used in particular as a base for surfactants, emulsifiers, emollients, lubricants or heavy metal salts.
