Abstract

See full text

Ester polyol esters are a unique class of lubricants that have adjustable molecular weights, viscosities, and pour points based on the character of their reaction materials and relative ratios. There is provided a method for preparing at least one ester polyol ester, the method comprising the method comprising preparing a reaction mixture comprising at least one polyol compound; at least one dicarboxylic acid; and at least one monocarboxylic acid, wherein the at least one polyol compound is esterified with the at least one dicarboxylic acid and the at least one monocarboxylic acid, wherein the reaction mixture has a hydroxyl group to carboxyl group ratio (HCR) corresponding to a ratio of moles of hydroxyl groups to moles of carboxyl groups, and the HCR is less than about 1.
