More particularly disclosed is a boron containing salt of an oil soluble hydroxylated amine and a hindered phenolic acid product prepared by: a) reacting an oil soluble hydroxylated amine of the general formula II: | 04-12-2012 |
20140038864 | METHOD FOR IMPROVING NITRILE SEAL COMPATIBILITY WITH LUBRICATING OILS - Provided are a lubricating engine oil and a method of improving nitrile seal compatibility with a lubricating oil in an engine lubricated with such lubricating oil. The method includes using as the lubricating oil a formulated oil comprising a lubricating oil base stock as a major component and one or more additives selected from the group consisting of (i) a sulfone, sulfolane, or derivative thereof; (ii) a borate ester, boron amide, or mixtures thereof; (iii) a sulfurized olefin; (iv) a thiadiazole or derivative thereof; and (v) a succinic anhydride or derivative thereof, as a minor component. Nitrile seal compatibility is improved as compared to nitrile seal compatibility achieved using a lubricating oil containing a minor component other than the one or more additives. | 02-06-2014 |
20140107000 | STABILIZED BLENDS CONTAINING ANTIOXIDANTS - The present invention relates to functional fluid compositions containing antioxidants, and specifically stable compositions containing antioxidants with limited solubility in and/or limited compatibility with the functional fluids with which they are used. In particular the present invention deals with functional fluids used in internal combustion engines, such as engine oils, and antioxidants containing a phenolic or benzoic group, where the antioxidant is present in the functional fluid composition at levels that would otherwise cause the composition to be unstable and/or hazy. | 04-17-2014 |
20140121140 | FRICTION MODIFIERS AND A METHOD OF MAKING THE SAME - A method of preparing a lubricating oil additive composition comprising reacting (A) a nitrogen-containing reactant derived from reacting a first reaction product with a triglyceride, wherein the first reaction product is derived by reacting an alkanolamine and a base, wherein the nitrogen-containing reactant comprises three equivalents of a nitrogen-containing compound and one equivalent of glycerol, and wherein the nitrogen-containing reactant contains less than 10 mass percent of glycerol alkyl ester; (B) a source of boron; and (C) glycerol. | 05-01-2014 |
20140243247 | ASHLESS OR REDUCED ASH QUATERNARY DETERGENTS - A composition of an oil-soluble ionic detergent that does not contribute metal ions to the composition, and which comprises a quaternary non-metallic pnictogen cation and an organic anion having at least one hydrocarbyl group of sufficient length to impart oil solubility to the detergent, the detergent having a total base number (TBN) to total acid number (TAN) ratio of at least 2:1 imparts ash-free basicity to a lubricant composition. | 08-28-2014 |
