Abstract

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.

First claim

The invention claimed is:

1. A composition comprising a triester compound of the following formula

wherein each R is independently a C 3-12 alkyl.

2. The composition of claim 1 , wherein each R is independently C 5-10 alkyl.

3. The composition of claim 1 , wherein each R is independently propyl, butyl, pentyl, hexyl, heptyl, octyl, decyl, undecyl, dodecyl, 2-methylbutyl, 3-methylbutyl, or a branched C 10 alkyl.

4. The composition of claim 3 , wherein each R is pentyl.

5. The composition of claim 3 , wherein each R is decyl.

6. The composition of claim 3 , wherein each R is 3-methylbutyl.

7. The composition of claim 3 , wherein each R is 2-methylbutyl.

8. The composition of claim 3 , wherein each R is a branched C 10 alkyl.

9. The composition of claim 3 , wherein each R is hexyl.

10. The composition of claim 3 , wherein each R is octyl.

11. The composition of claim 1 , wherein the composition is a lubricant composition.

12. The composition of claim 11 , wherein the composition further comprises one or more additional base oils selected from the group consisting of an API Group I base oil, an API Group II base oil, an API Group III base oil, an API Group IV base oil, an API Group V base oil, and combinations thereof.

13. The composition of claim 12 , wherein the composition comprises the triester compound in an amount ranging from 1 to 75 percent by weight, based on the total weight of the composition.

14. The composition of claim 13 , wherein the composition comprises the triester compound in an amount ranging from 5 to 60 percent by weight, based on the total weight of the composition.

15. The composition of claim 12 , further comprising a dispersant, a detergent, or a combination thereof.

16. The composition of claim 12 , further comprising a pour point depressant.

17. The composition of claim 12 , further comprising a viscosity modifier.

18. The composition of claim 12 , further comprising an anti-foam agent.

19. The composition of claim 12 , further comprising a thickener.

20. The composition of claim 12 , further comprising additives selected from the group consisting of: corrosion-inhibiting agents, oxidation-inhibiting agents, pour point depressing agents, extreme pressure agents, antiwear agents, viscosity index improvers, friction modifiers, hindered amines, phenolic inhibitors, sulfurized inhibitors, antioxidants, metal cutting additives, antimicrobial additives, color stabilizers, viscosity modifiers, demulsifiers, seal swelling agents, anti-foam agents, and any combinations thereof.
