Abstract

Disclosed herein is a lubricant composition comprising soybean oil; and molybdenum disulfide; the molybdenum disulfide being dispersed in the soybean oil. Disclosed herein too is a method comprising agitating molybdenum disulfide with soybean oil in a reactor; the mixing being conducted in the presence of a magnetic field that is greater than the earth'"'"'s field and an electrical field. Disclosed herein too is a coolant composition comprising water; soap and/or a surfactant; and a lubricant composition; the lubricant composition comprising soybean oil and molybdenum disulfide. Disclosed herein too is a method of manufacturing a coolant composition comprising mixing a lubricant composition, water and soap; the lubricant composition comprising a base oil and a metal sulfide.

Claims

1. A lubricant composition comprising:

soybean oil; and

molybdenum disulfide;

the molybdenum disulfide being dispersed in the soybean oil in the presence of an electrical field, wherein the electric field is applied using a voltage greater than or equal to about 3 volts, further wherein the molybdenum disulfide comprises particles having an average particle size of about 10 to about 100 nanometers after becoming a part of the lubricant composition.

2. The lubricant composition of claim 1, wherein the soybean oil is a saturated oil.

3. The lubricant composition of claim 1, wherein the soybean oil is an unsaturated oil.

4. The lubricant composition of claim 1, wherein the soybean oil comprises C₁₂-C₂₀ saturated fatty acids.

5. The lubricant composition of claim 1, wherein the lubricant composition comprises about 0.1 pounds to about 4 pounds of molybdenum disulfide per 11 gallons of the soybean oil.

6. The lubricant composition of claim 1, further comprising canola oil.

7. The lubricant composition of claim 1, further comprising a petroleum based oil.

17. A coolant composition comprising:

water;

soap and/or a surfactant; and

the lubricant composition of claim 1.

18. The coolant composition of claim 17, wherein the soap and/or surfactant is generally added in an amount of about 0.01 to about 5 gallons per gallon of the lubricant composition.

19. The coolant composition of claim 17, wherein the water is added in an amount of about 0.01 to about 50 gallons per gallon of the lubricant composition.

20. The coolant composition of claim 17, wherein the soap is present in an amount of about 1 weight percent to about 5 weight percent, based on the total amount of the coolant composition.

8. A lubricant composition comprising:

a vegetable oil; and

molybdenum disulfide particles;

the molybdenum disulfide particles being dispersed in the vegetable oil in the presence of an electrical field and a magnetic field, wherein the electric field is applied using a voltage greater than or equal to about 3 volts, further wherein the molybedenum sulfide particles have an average particle size of about 10 to about 100 nanometers after becoming a part of the lubricant composition.

9. The lubricant composition of claim 8, wherein the vegetable oil is a soybean oil, a canola oil, a castor bean oil, a sunflower seed oil, a peanut oil, a corn oil, a safflower seed oil, a linseed oil, jatropha oil, an apricot seed oil, a mango oil, a coconut oil, a cashew nut oil, or a combination comprising at least one of the foregoing base oils.

21. A coolant composition comprising:

water;

soap and/or a surfactant; and

the lubricant composition of claim 8.

22. The coolant composition of claim 21, wherein the vegetable oil is soybean oil.

10. A method comprising:

agitating molybdenum disulfide with a vegetable oil;

the agitating being conducted in the presence of a magnetic field that is greater than the earth'"'"'s field and an electrical field, wherein the electric field is applied using a voltage greater than or equal to about 3 volts, further wherein the molybdenum disulfide comprises particles having an average particle size of about 10 to about 100 nanometers after becoming a part of the lubricant composition.

11. The method of claim 10, wherein the agitating comprises stirring.

12. The method of claim 10, wherein the magnetic field has a strength of greater than or equal to about 3,000 gauss.

13. The method of claim 10, wherein the magnetic field has a strength of greater than or equal to about 20,000 gauss.

14. The method of claim 10, wherein the electric field is applied using a direct current voltage to the reactor.

15. The method of claim 14, wherein the direct current is greater than or equal to about 6 volts.

16. The method of claim 14, wherein the direct current is greater than or equal to about 12 volts.

23. A method of manufacturing a coolant composition comprising:

mixing a lubricant composition, water and soap;

the lubricant composition comprising a vegetable oil and a molybdenum disulfide, the molybdenum disulfide being dispersed in the vegetable oil in the presence of an electrical field, wherein the electric field is applied using a voltage greater than or equal to about 3 volts, further wherein the molybedenum disulfide comprises particles having an average particle size of about 10 to about 100 nanometers after becoming a part of the lubricant composition.

24. The method of claim 23, wherein the vegetable oil is soybean oil.
