Abstract: The present invention is directed to lubricating oils exhibiting improved resistance to oxidation and deposit/sludge formation comprising a lubricant base oil and catalytic antioxidants comprising an effective amount of a) one or more polymetal organometallic compound; and, b) effective amounts of one or more substituted N,N?-diaryl-o-phenylenediamine compounds or c) one or more hindered phenol compounds or both, to a method for improving the antioxidancy and the resistance to deposit/sludge formation of formulated lubricating oil compositions by the addition thereto of an effective amount of the aforementioned catalytic antioxidants, and to an additive concentrate containing the aforementioned catalytic antioxidants.

Abstract: A method of coloring a substrate is disclosed that includes the steps of dissolving a vegetable oil ester based solvent wherein the ester is selected from a group consisting of esters having carbon chain length of C-1 to C-18 in a liquid solvent dye to form a low-sulfur containing dye formulation such that the vegetable oil ester is present in an amount of between about 5 and 80 percent by weight of the dye formulation, and mixing sufficient amounts of the dye formulation with the substrate to produce mixtures of predetermined color in which the levels of toxic substrate are substantially less than in otherwise equivalent mixtures that include hydrocarbon-based solvents.

Abstract: An aqueous lubricant is provided which by simple application onto metal surfaces forms lubricating films required for heavy working of metals, and which contains no oil. The aqueous lubricant is prepared by suspending or dispersing a metal chelate compound in water with a surfactant or the like. The metal chelate compound has a polydentate or multidentate chelate ligand, in which at least one of the coordinating atoms is sulfur, coordinated to the coordination site of at least one metal species selected from among zinc, manganese, iron, molybdenum, tin and antimony. When applied onto metal surfaces, the aqueous lubricant forms effective lubricating films on the metal surfaces. The lubricating films contain sulfur as coordinating atoms and therefore, extreme pressure produces sulfur radicals through decomposition by tribo-chemical reactions. The sulfur radicals are highly reactive and react rapidly with the metal surface to produce metal sulfides with a lubricating effect.

Abstract: The invention relates to a lubricating composition comprising a base oil of lubricating viscosity, a hydroxy-substituted dithiocarbamate, an organo-molybdenum compound, and optionally a phosphorous source.

Abstract: Lubricants are taught that can quickly and easily form a lubricating layer on a metal surface of a metal before plastic processing. Such lubricants preferably include a primary lubricating agent or component having a bridge complex that satisfies the following conditions: (1) the complex contains at least two central metal atoms; (2) at least one first multidentate ligand forms a bridge between two central metal atoms; and (3) at least one second multidentate ligand is bound to at least one central metal atom and has at least one coordinating atom that can coordinate with metal atoms, but which is not coordinated with any of the central metal atoms or is only partially coordinated with at least one of those central metal atoms. A third multidentate ligand is preferably also bound to one of the central metal atoms and may preferably include at least two sulfur atoms that are coordinated to the central metal atom.

Abstract: A lubricant composition for a surface treatment of a steel filament comprises at least one specified compound as a lubricant component and a rubber-steel filament composite body is prepared by using a steel filament treated with the lubricant composition.
