20120214717 | NANOPARTICLE ADDITIVES AND LUBRICANT FORMULATIONS CONTAINING THE NANOPARTICLE ADDITIVES - A method for making a self-dispersing cerium oxide nanoparticles additive for lubricants, a lubricant composition containing the nanoparticles and a method for reducing boundary friction using the nanoparticles. The nanoparticles are made by an improved process of reacting a mixture of organo-cerium salt, fatty acid, and amine in the substantial absence of water and organic solvent at a temperature ranging from about 150° to about 250° C., the improvement comprising reacting the organo-cerium salt, fatty acid and amine in a molar ratio ranging from about 1:1:1 to about 1:2:2 in the reaction mixture to provide the reaction product comprising from about 20 to about 40% by weight of the nanoparticles in a substantially organic medium. | 08-23-2012 |
20120291737 | LUBRICANT COMPOSITIONS CONTAINING A HETEROAROMATIC COMPOUND - An ashless additive for lubricating oil compositions, lubricating oil compositions and methods for lubricating that are effective to improve the total base number (TBN) of a lubricant composition. The additive is a reaction product of a compound of the formula: | 11-22-2012 |
20130040866 | LUBRICANT COMPOSITIONS CONTAINING A FUNCTIONALIZED DISPERSANT - An engine lubricant composition, a method for maintaining the soot or sludge handling capability of an engine lubricant while not adversely affecting elastomeric seal material in the engine and a method of operating an engine. The engine lubricant includes a base oil and a dispersant. The dispersant is a reaction product of A) a hydrocarbyl-dicarboxylic acid or anhydride, B) a polyamine, C) a dicarboxyl-containing fused aromatic compound, and D) a non-aromatic dicarboxylic acid or anhydride. | 02-14-2013 |
