Cyclic phosphonate esters for lubricant applications
Lubricant compositions comprising (a) an oil of lubricating viscosity and (b) a phosphonate ester other than a zinc salt. The phosphonate ester may be the reaction product of (i) phosphonic acid or a monomeric ester thereof with (ii) a propanediol having hydroxy groups in both the 1 and 3 positions and one or more of the carbon atoms of the propyl units are substituted with one or more alkyl groups such that the total number of carbon atoms in the propanediol ranges from 4 to 12. The molar ratio of (i) to (ii) may be 0.9:1.1 to 1.1 to 0.9.
Polyurea lubricating greases containing carbonates, and their use
The invention relates to polyurea lubricating grease compositions containing polyurea thickeners and at least one organic carbonate, to lubrication points or components containing the polyurea lubricating grease composition, to a seal comprising sealing material from fluorinated elastomers and to the use of the lubricating greases.
High viscosity base fluids based on oil compatible polyesters prepared from long-chain epoxides
A polyester is useful as a high viscosity base fluid. A method for its preparation involves epoxidizing an alpha-olefin, reacting the alpha-epoxide or diol with a saturated linear aliphatic dicarboxylic acid, and isolating the polyester. Lubricant compositions can contain such polyesters and the compositions are useful as automatic transmission fluids, manual transmission fluids, continuously variable transmission fluids, gear oil formulations, industrial gear oil formulations, axle fluid formulations, dual clutch transmission fluids, dedicated hybrid transmission fluids, or as hydraulic oils.
Lubricant base oil
A lubricant base oil of the present invention includes an ester compound including: a structural moiety (A) that is derived from an alcohol compound (A); and a structural moiety (B) that is derived from a carboxylic acid, the structural moiety B including: a structural moiety (B1) that is derived from a monocarboxylic acid (B1); and a structural moiety (B2) that is derived from an aliphatic monocarboxylic acid (B2) having 4 or more and 18 or less carbon atoms. According to the present invention, it is possible to provide a lubricant base oil having excellent low-temperature stability and high heat resistance while maintaining torque-lowering properties.
