Abstract

A lubricant additive produced by various processes, including mixing an organophosphate and an organofluorine compound, reacting an organophosphate and an organofluorine compound, reacting a fluorinated organophosphate and an organofluorine compound (with or without molybendum disulfide), or reacting an organophosphate, a metal halide and an organofluorine compound (with or without molybendum disulfide), to produce a reaction mixture comprising the lubricant additive. Also, a lubricant produced by various processes, including mixing an organophosphate and an organofluorine compound, reacting an organophosphate and an organofluorine compound, reacting a fluorinated organophosphate and an organofluorine compound (with or without molybendum disulfide), or reacting an organophosphate, a metal halide and an organofluorine compound (with or without molybendum disulfide), and adding at least a portion of the reaction mixture to a lubricant base.

Claims (38)

1. A method for producing a lubricant comprising:

forming a mixture by mixing an organophosphate and an organofluorine wherein the organophosphate is ZDDP or fluorinated ZDDP and the organofluorine is FI-PTFE; and

adding at least a portion of the mixture to a lubricant base, wherein said produced lubricant comprises from about 0.01 weight percent phosphorous to about 0.5 weight percent phosphorous.

2. The method of claim 1 wherein said FI-PTFE molecule comprises greater than 40 carbon atoms.

3. The method of claim 1 wherein the ZDDP is selected from the group consisting of neutral ZDDP (primary), neutral ZDDP (secondary), basic ZDDP (primary), basic ZDDP (secondary), ZDDP salt, and combinations thereof.

4. The method of claim 1 wherein the FI-PTFE has at least one functional group consisting of carboxylic acids, sulfonic acids, ester, alcohols, amines, amides, or mixtures thereof.

5. A method for producing a lubricant said method comprising:

adding an organophosphate and an organofluorine to a lubricant base wherein the organophosphate is ZDDP or fluorinated ZDDP and the organofluorine is FI-PTFE; and

mixing said organophosphate and said organofluorine in said lubricant base to produce a lubricant

wherein the FI-PTFE has at least one functional group consisting of carboxylic acids, sulfonic acids, ester, alcohols, amines, amides, or mixtures thereof; and

wherein said produced lubricant comprises from about 0.01 weight percent phosphorous to about 0.5 weight percent phosphorous.

6. The method of claim 5 wherein said FI-PTFE molecule is comprised of more than 40 carbon atoms.

7. A method for producing a lubricant comprising:

reacting an organophosphate and an organofluorine wherein the organophosphate is ZDDP or fluorinated ZDDP and the organofluorine is FI-PTFE and wherein the FI-PTFE has at least one functional group consisting of carboxylic acids, sulfonic acids, ester, alcohols, amines, amides, or mixtures thereof.

8. The method of claim 7 further comprising:

adding at least a portion of products of the reaction to a lubricant base, wherein said produced lubricant comprises from about 0.01 weight percent phosphorous to about 0.5 weight percent phosphorous.

9. The method of claim 7 wherein the reaction takes place in a lubricant base and said lubricant produced comprises from about 0.01 weight percent phosphorous to about 0.5 weight percent phosphorous.

10. The method of claim 7 wherein said FI-PTFE molecule is comprised of more than 40 carbon atoms.

11. The method of claim 7 wherein said ZDDP is fluorinated.

12. The method of claim 7 wherein the ZDDP is selected from the group consisting of neutral ZDDP (primary), neutral ZDDP (secondary), basic ZDDP (primary), basic ZDDP (secondary), ZDDP salt, and combinations thereof.

13. The method of claim 7 wherein said reacting comprises reacting from about 20 minutes to about 24 hours.

14. The method of claim 7 wherein said reacting comprises reacting at a temperature of about 40° C. to about 125° C.

15. A method of producing a grease, said method comprising:

forming a mixture by mixing an organophosphate and an organofluorine wherein the organophosphate is ZDDP or fluorinated ZDDP and the organofluorine is FI-PTFE; and

adding at least a portion of the mixture to a grease base so as to give said grease extreme pressure and anti-wear properties;

wherein said grease produced comprises from about 0.01 weight percent phosphorous to about 0.5 weight percent phosphorous.

16. The method of claim 15 wherein said FI-PTFE molecule comprises more than 40 carbon atoms.

17. A method of producing a grease, said method comprising:

adding an organophosphate and an organofluorine wherein the organophosphate is ZDDP or fluorinated ZDDP and the organofluorine is FI-PTFE having at least one functional group consisting of carboxylic acids, sulfonic acids, ester, alcohols, amines, amides, or mixtures thereof; and

reacting said organophosphate and said organofluorine in said grease base so as to form a grease with extreme pressure and anti-wear properties; wherein said grease produced comprises from about 0.01 weight percent phosphorous to about 0.5 weight percent phosphorous.

18. The method of claim 17 wherein said FI-PTFE molecule comprises more than 40 carbon atoms.

19. The method of claim 18 wherein said ZDDP is fluorinated.

20. The method of claim 17 wherein said reacting comprises reacting from about 20 minutes to about 24 hours.

21. The method of claim 17 wherein said reacting comprises reacting at a temperature of about 40° C. to about 125° C.

22. The method of claim 17 wherein said adding further comprises adding molybdenum disulfide, a fluorinated organophosphate, and an organofluorine to a grease base and said reacting comprises reacting said molybdenum disulfide, said fluorinated organophosphate, and said organofluorine in said grease base.

23. A method for producing a lubricant comprising:

forming a mixture by mixing ZDDP and FI-PTFE; and

adding at least a portion of the mixture to a lubricant base, wherein said produced lubricant comprises from about 0.01 weight percent phosphorous to about 0.5 weight percent phosphorous.
