Abstract
Branched-chain aliphatic ester oils comprising full esters of branched-chain aliphatic polyols having from 2 to 6 hydroxyl groups with saturated, branched-chain, aliphatic monocarboxylic acids having from 14 to 22 carbon atoms, as well as their use alone, or as mixture components, as lubricants or hydraulic fluids.

A branched-chain aliphatic ester oil consisting essentially of a full ester of a branched-chain aliphatic polyol having only from 2 to 6 primary hydroxyl groups selected from the group consisting of alkanepolyols having from 3 to 6 carbon atoms and alkoxyalkanepolyols having from 6 to 12 carbon atoms with .alpha.-branched-chain alkanoic acids having the formula ##STR6## wherein R.sub.1 and R.sub.2 are straight-chained alkyl having from 1 to 19 carbon atoms and the total number of carbon atoms in the acid is from 14 to 22, said acids being selected from the group consisting of (1) acids derived from the oxidation of .alpha.-branched alcohols formed from normal alcohols by the Guerbet synthesis and (2) an acid of the formula ##STR7##
