A process for preparing a composition comprising a mixture with ester and amine function in the form of ester-amines, amines, salts of amines, monoglycerides and diglycerides all derived from monomeric, dimeric, trimeric, and/or tetrameric fatty acids contained in polymerized polyunsaturated oil comprising: (a) polymerizing a polyunsaturated vegetable or animal oil to form a polymerized oil, (b) treating the polymerized oil with water vapor, and (c) reacting the polymerized oil with an excess of at least one compound containing at least one hydroxyl function and at least one tertiary amine function, optionally in the presence of a catalyst. Said methods further comprise adding the compositions to an oil effluent as dispersing agents for hydrates.

Methods of making emulsifying and dispersing surfactants and their use

Process for the manufacture of compositions which can be used as emulsifying and dispersing surfactants the compositions obtained and their uses

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.

Process for the codimerization of fatty substance dienes and olefins that are catalyzed by nickel complexes

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.

Process for the codimerization of polyunsaturated fatty substances and olefins by iron complexes

The following are described herein: a composition that consists of a mixture that comprises at least amides, amines, ester-amides, ester-amines, amine salts and monoglycerides, that are all derived from monomeric, dimeric, trimeric and/or tetrameric fatty acids; a process for the production of said composition which comprises the transamidification reaction of a polyunsaturated vegetable oil that is polymerized thermally, with an excess of at least one amino alcohol, which may or may not be in the presence of a catalyst; and the uses of this composition particularly as an emulsifying agent that allow it, depending on the nature of the oil, to form an oil-in-water or water-in-oil emulsion, as a solid-dispersing agent, or as an agent for the stabilization of foams in a liquid or an emulsion.
