Abstract (en)

[origin: US2018179463A1] Provided is a polyol ester base stock composition with reduced odor and volatility. The polyol ester back stock composition does not include C5 acid. More particularly, the polyol ester base stock includes the reaction product of: (a) a polyol represented by the formula R(OH)n wherein R is an aliphatic or a cyclo-aliphatic hydrocarbyl group and n is at least 2, and (b) a mixture of monocarboxylic acids comprising at least one linear acid selected from the group consisting of between C6 to C10 acids and at least one branched C6 acid, wherein the amount of C6 to C10 acids is at least 55 wt. % and the amount of the at least one branched C6 acid is 45 wt. % or less, based upon the total amount of said mixture of monocarboxylic acids. The polyol ester base stock is particularly suited for aviation turbine oils.
