Abstract

The invention relates to novel compositions of matter which may advantageously be used as lubricants or pressure transfer media or else for functional liquids and lubricant additives. The lubricants according to the invention are the reaction products of an electro-philic addition of linear or branched, aliphatic or aromatic carboxylic acids, carboxylic anhydrides, carbonyl halides or novel neoacids to the double bonds of fatty acids, esters thereof and/or of other fatty acid derivatives and also of synthetic esters. Owing to their increased oxidation resistance compared to the starting materials and also their low toxicity, the novel class of synthetic esters based on oleochemicals may find use in novel environmentally compatible lubricants, pressure transfer systems, functional liquids and lubricant additives.
