Abstract

The invention comprises dibasic acid esters of the formula <FORM:0722634/IV (b)/1> in which n is a number from 2 to 8, R is a straight chain alkyl radical containing from 4 to 12 carbon atoms and R1 is a branched chain alkyl radical, preferably the hydrocarbon radical of an Oxo alcohol, containing from 4 to 13 carbon atoms. Suitable dibasic acids for the formation of these esters are succinic, glutaric, adipic, pimelic, suberic, azelaic and sebacic acids or mixtures thereof. The straight chain alcohol (ROH) may be lauryl, n-decyl, n-nonyl, n-heptyl, and the like. These esters are prepared by standard methods. The properties of the esters of adipic acid in which (a) R is n-hexyl and R1 is the hydrocarbon radical of a C8 Oxo alcohol and (b) R is n-butyl and R1 is the hydrocarbon radical of a C10 Oxo alcohol are described.ALSO:Synthetic lubricating compositions comprise a dibasic acid ester of the formula <FORM:0722634/III/1> in which n is a number from 2 to 8, R is a straight chain alkyl radical containing from 4 to 12 carbon atoms and R1 is a branched chain alkyl radical, preferably the hydrocarbon radical of an oxo radical, containing from 4 to 13 carbon atoms. These esters may be used directly as lubricants or may be blended with other lubricants such as mineral oils or other synthetic lubricants. Improvers such as viscosity index improvers, pour point depressors, oxidation inhibitors, detergents, corrosion resisting and rust preventive agents, may also be added. The esters of adipic acid in which (a) R is n-hexyl and R1 is the hydrocarbon radical of a C8 oxo-alcohol and (b) R is n-butyl and R1 is the hydrocarbon radical of a C10 oxo alcohol are described.
