Abstract
A lubricant composition useful for high temperature applications is provided comprising at least one polyol polyester derived from the reaction product of a neopentyl polyol with 5,7,7-trimethyl-2-(1,3,3-trimethylbutyl)-octanoic acid. The lubricants have low evaporation loss, high resistance to oxidation, and provide reduced deposits when utilized alone or in combination with other materials.
Claims22
A lubricant composition comprising at least one polyol polyester, wherein the polyol polyester comprises a reaction product of:
- a) at least one neopentyl polyol, and
- b) 5,7,7-trimethyl-2-(1,3,3-trimethylbutyl)-octanoic acid or a reaction product, mixture, or copolymer thereof, or a further reaction product, further mixture or further copolymer of the reaction product.
A method of lubricating a metal surface, comprising:
- applying a lubricant composition to a metal surface, wherein the lubricant composition comprises:
- a) a reaction product of at least one neopentyl polyol and 5,7,7-trimethyl-2-(1,3,3-trimethylbutyl)-octanoic acid or a reaction product, mixture, or copolymer thereof wherein the reaction product is a base oil in the composition,
- b) from about 0.5 to about 15 percent by weight of at least one lubricant protecting additive, and
- c) from about 0.1 to about 10 percent by weight of at least one metal protecting additive.
A method of making a lubricant composition, comprising reacting
- a) at least one neopentyl polyol and
- b) 5,7,7-trimethyl-2-(1,3,3-trimethylbutyl)-octanoic acid or a reaction product, mixture, or copolymer thereof, wherein the reaction product is a base oil in the composition.
