Abstract:
A composition comprises the reaction product of a dithiophosphate derivative and an amine. The reaction product is present in the composition in an amount of at least about 25 wt. %. The composition may include additional components. A method of forming the composition comprises the step of combining the dithiophosphate derivative and the amine to form the composition. A method of increasing thermal stability of a dithiophosphate derivative comprises the step of combining the dithiophosphate derivative and an amine. The dithiophosphate derivative can decompose to form hydrogen sulfide (H2S). However, the amine substantially prevents thermal decomposition of the dithiophosphate derivative. An example of the dithiophosphate derivative is 3-(di-isobutoxy-thiophosphorylsulfanyl)-2-methyl-propanoic acid. An example of the amine is ditridecyl amine. The composition can be used for a variety of applications. For example, the composition can be used as an antiwear compound/additive in lubricants, metalworking fluids, hydraulic fluids, etc.

Claim (Index 34):
The composition as set forth in  claim 21 , meeting Occupational Safety & Health Administration (OSHA) Standard 29 CFR 1910.1000, TABLE Z-2 for hydrogen sulfide (H 2 S) exposure which requires that exposures not exceed 20 parts per million (ppm) subject to an exception that if no other measurable exposure occurs during an 8-hour work shift, exposures may exceed 20 ppm, but not more than 50 ppm, for a single time period up to 10 minutes.
