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.
Abstract:
The present disclosure provides an additive package for a lubricant composition that includes an alkoxvlated amide, an ester, and an anti-wear agent including phosphorus, molybdenum, or a combination thereof. The present disclosure also provides a lubricant composition that includes a base oil, the alkoxvlated amide, the ester, and the anti-wear agent including phosphorus, molybdenum, or a combination thereof. The present disclosure further provides a method of lubricating an internal combustion engine for improving fuel economy.
Abstract:
The instant disclosure provides a lubricant composition having improved four- ball antiwear properties. The lubricant composition includes a base oil and one or more alkylethercarboxylic acid corrosion inhibitor(s) having the formula: (formula) wherein R is a straight or branched chain C 6 -C 18 alkyl group and n is a number of from 0 to 5. The lubricant composition also includes an ashless antiwear additive including phosphorous. The four-ball antiwear properties are reported as an average diameter of wear scars pursuant to ASTM D4172. The average diameter of the wear scars resulting from the lubricant composition are at least 5% smaller than the average diameter of the wear scars resulting from a standard that includes the base oil and the antiwear additive and that is free of the one or more alkylethercarboxylic acid corrosion inhibitor(s).
Abstract:
A lubricant composition having improved non-Newtonian viscometrics includes at least 85 weight percent of a base oil and 1 to 15 weight percent of a lubricant additive. The additive itself includes 10 to 80 weight percent of a diluent oil and 30 to 80 weight percent of a random co-polymeric viscosity index improver. The viscosity index improver is the free -radical polymerization product of at least 5 to 15 weight percent methyl methacrylate and 5 to 95 weight percent of a C 8 -C 10 alkyl (meth)acrylate. The additive is formed using a method that includes the step of providing the diluent oil, the methyl methacrylate, the C 8 -C 10 alkyl (meth)acrylate, and a free-radical initiator. The method also includes the steps of flowing the diluent oil into a reactor, flowing the methyl methacrylate and the C 8 -C 10 alkyl (meth)acrylate into the reactor independently from the free-radical initiator, and flowing the free-radical initiator into the reactor.
Abstract:
A lubricant composition includes a base oil and an additive package. The additive package includes a seal compatibility additive chosen from a halide seal compatibility additive, an epoxide seal compatibility additive, a boroxine seal compatibility additive, a sulfonate ester seal compatibility additive, and combinations thereof. The alkoxylated amide and the ester are set forth in general formulas A and B, respectively: In general formulas A and B, each R 13 , R II , R III , and R IV , is, independently, a linear or branched, saturated or unsaturated, hydrocarbyl group. In addition, at least one of R II and R III include an alkoxy group, and R IV includes an amine group.
Abstract:
This disclosure is directed to a lubricant composition having improved compatibility with fluoropolymer seals. The lubricant composition includes a base oil and a sulfonate ester. The disclosure is also directed to an additive package for a lubricant composition that provides improved compatibility with fluoropolymer seals. The additive package includes the sulfonate ester. The disclosure is also directed to a method of improving compatibility of a lubricant composition with a fluoropolymer seal disposed in an internal combustion engine. The sulfonate ester improves the compatibility with fluoropolymer seals of the resultant lubricant composition.
