摘要： Composition comprising at least one ester of one or more saturated C 18 fatty acids and an alcohol, wherein the fatty acids have between 1 and 3 pairs of vicinal ester groups of formula R 1 COO-, the two vicinal ester groups in each pair being different, R 1 is a radical independently selected from linear or branched (C 1 -C 18 ) alkyl; and the alcohol is selected from the group consisting of a (C 1 -C 15 ) linear or branched monohydric alcohol and a (C 2 -C 6 ) polyhydric alcohol having between 2 and 4 hydroxyl groups obtainable by a process comprising: a) epoxidizing a product comprising at least an ester of an unsaturated C 18 fatty acid and of an alcohol; followed by ring opening of the epoxide and b) reacting the compound obtained in step a) with a (C 1 -C 18 ) linear or branched carboxylic acid different from the one used in step a). The composition obtainable by the process of the invention is useful as lubricant base stock oil or as an additive to modulate the viscosity and/or the pour point of lubricant compounds.
