·
OSTI ID:6158597
An ester, adapted for use as a component of a multigrade lubricating oil, is prepared by reacting: A. A mixture of bifunctional and trifunctional polyols wherein the molar ratio of the bifunctional polyols to the trifunctional polyols is in the range of 1:2.5 to 1:10; and B. A mixture of linear monocarboxylic acids containing from 6 to 8 carbon atoms, wherein the molar average is c7, and of linea monocarboxylic acids containing from 12 to 18 carbon atoms, the molar ratio of the c6 to c8 acids and the c12 to c18 acids being in the range of from 4:1 to 19:1.
