  • Automatic transmission fluid comprising esters derived from a particular monocarboxylic acid composition
    Patent number: 4263159
    Abstract: An automatic transmission fluid consisting of a base ester fluid, and optionally other additives. The base ester fluid is the reaction product of:(a) an aliphatic polyol containing from 2 to 6 primary hydroxyl groups, with(b) a monocarboxylic acid composition comprising:(i) a low molecular weight acid composition, and(ii) an alpha-branched acid composition.The low molecular weight acid composition is comprised of at least one saturated monocarboxylic acid of from 3 to 8 carbon atoms.The alpha-branched acid composition is comprised of at least one saturated monocarboxylic acid of from 11 to 13 carbon atoms. The alpha-branched acid composition contains at least about 40% by weight of alpha-branched monocarboxylic acid.The molar ratio of acid composition (i) to acid composition (ii) is sufficient to produce a base ester fluid having a pour point no greater than -40.degree.
