权利要求: What is claimed is:1. A new composition of matter, suitable for addition to a composition selected from the group consisting of hydrocarbon liquids and synthetic ester lubricants, which comprises an ester, formed by reacting an oil-insoluble glycol having between about 2 and about 8 carbon atoms per molecule with a hydrogenated dimer of a C12 to Ci8 unsaturated monocarboxylic acid, said ester being selected from the group consisting of monomeric esters having the formulae:HOOC—R—COOR'—OHHO—R'—OOC—R—COO—R'—OHand esters formed by reacting a hydrogenated dimer of said carboxylic acid with said glycol in the mole ratio of 2 to 1 respectively, wherein R is the hydrocarbon radical of the said dimer acid and R' is the hydrocarbon radical of said glycol.2. A composition of matter as in claim 1 wherein the acid is the hydrogenated mixed dimer of linoleic and oleic acids.3. A composition of matter as in claim 1 wherein the acid is the hydrogenated dimer of linoleic acid.4. A composition of matter as in claim 1 wherein the acid is the hydrogenated dimer of oleic acid.5. A composition of matter as in claim 1 wherein the glycol is ethylene glycol.6. A composition of matter as in claim 1 wherein the glycol is ethylene glycol and the acid is the hydrogenated mixed dimer of linoleic and oleic acids.7. A composition of matter comprising a major amount of a liquid selected from the group consisting of hydrocarbon liquids and synthetic ester lubricants, and a minor amount of the composition of claim 1.8. A composition of matter as in claim 7 wherein the liquid is a jet fuel and the ester is present in an amount ranging between about 0.001 and about 0.4 wt. percent.9. A composition of matter as in claim 7 wherein the liquid is a mineral lubricating oil and the ester is present in an amount ranging between about 0.001 and about 4.9 wt. percent.10. A composition of matter as in claim 8 wherein the ester is a partial ester.11. A composition of matter as in claim 9 wherein the ester is a partial ester.12. A composition of matter as in claim 8 wherein the acid is the hydrogenated dimer of linoleic acid.13. A composition of matter as in claim 8 wherein the acid is a hydrogenated dimer of oleic acid.14. A composition of matter as in claim 8 wherein the acid is a hydrogenated mixed dimer of linoleic and oleic acids.15. A composition of matter as in claim 8 wherein the glycol is ethylene glycol.
