Maleinized Ester Derivatives

摘要

This disclosed invention relates to a maleinated ester derivative derived from an unsaturated linear aliphatic carboxylic acid methyl ester, maleic anhydride, and a monohydric alcohol. Lubricants and functional fluids containing the maleinated esters are disclosed.

主权项

1. A composition comprising a maleinized ester derivative made by the reaction of:
(i) methyl 9-dodecenoate; and (ii) maleic anhydride; and (iii) a monohydric alcohol of 3 to about 12 carbon atoms; wherein the maleinized ester derivative comprises at least two proximal ester groups and another ester group, the proximal ester groups and the another ester group containing straight chain alkyl groups of 3 to about 12 carbon atoms; the proximal ester groups being separated from the another ester group by at least about 8 carbon atoms; and wherein the maleinized ester derivative contains one or more carbon-carbon double bonds, the one or more carbon-carbon double bonds being hydrogenated to form saturated carbon bonds.
