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.
Claims17
Process for obtaining a codimer, characterized in that at least one monoolefinic compound is added to a fatty substance that comprises at least two conjugated or unconjugated ethylene bonds, in the presence of a catalytic system that comprises at least one iron compound, at least one reducing compound, and at least one ligand that contains phosphorus, arsenic, antimony or nitrogen.
