摘要： The invention relates to a method for the preparation of estolide esters from a hydroxycarboxylic acid by a reaction of addition of a fatty acid to the hydroxyl function and by a reaction of esterification of the carboxylic acid function with an alcohol. The invention further relates to the use of estolide esters as a base oil in a lubricating composition or as an emollient in a cosmetic or pharmaceutical composition.

摘要： The invention relates to a composition preparation method for preparing a composition of estolides, the method comprising reacting an unsaturated compound of a type such as an acid or ester, with a saturated fatty acid; in the presence of a catalyst of a type such as sulphonic acid, the said method including no vacuum distillation step thereby making it possible to separate the monoestolides from the polyestolides. The invention also relates to a composition of estolides that is obtainable by the method according to the invention and the use thereof in lubricating compositions.
