Title (EN) CASTOR OIL FATTY ACID BASED ESTOLIDE ESTERS AND THEIR DERIVATIVES AS POTENTIAL LUBRICANT BASE STOCKS
(FR) ESTERS D'ESTOLIDES À BASE D'ACIDES GRAS D'HUILE DE RICIN ET LEURS DÉRIVÉS, POUVANT SERVIR DE SUPPORT POUR LUBRIFIANTS
Abstract: front page image
(EN)Castor oil was hydrolysed to castor fatty acids and self condensed to get a ricinoleic acid- based estolide of about 95 acid value. The carboxylic group of the estolide on subsequent esterification with linear or branched chain alcohols and also on acetylation of free hydroxy group yielded castor oil fatty acids based estolide esters and their acetates. All the products were evaluated for total acid number (TAN), viscosity, viscosity index, pour point, flash point, and copper strip corrosion and found to be potential lubricant basestocks.
(FR)La présente invention concerne de l'huile de ricin ayant été hydrolysée pour donner des acides gras d'huile de ricin, puis ayant subi une autocondensation en vue de l'obtention d'un estolide à base d'acide ricinoléique d'un indice d'acide d'environ 95. Le groupe carboxylique de l'estolide, suite à une estérification ultérieure avec des alcools à chaîne linéaire ou ramifiée, ainsi qu'à l'acétylation du groupe hydroxy libre, donne des esters d'estolides à base d'acides gras d'huile de ricin et leurs acétates. On a procédé à une évaluation de tous les produits en termes d'indice d'acide total (TAN), de viscosité, d'indice de viscosité, de point de congélation, de point d'éclair et de corrosion à la lame de cuivre, ce qui a permis de déterminer qu'ils peuvent servir de support pour lubrifiants.
