Abstract: Nitrogen oxygenates and particulate emissions in combustion engines are effectively suppressed when a minor effective amount of a transition metal energy transfer additive, e.g., iron, cobalt and copper complexed with a thiobisphenol are added to the engine's fuel.

Abstract: The cloud point of a hydrodewaxed base stock is reduced by direct sulfurization of the base stock, or by direct sulfurization of the base stock in the presence of a magnesium, calcium or barium compound.

Abstract: The cloud point of a hydrodewaxed base stock is reduced by direct sulfurization of the base stock, or by direct sulfurization of the base stock in the presence of a magnesium compound.

Abstract: Dimercaptothiadiazole adducts of hydroxyl-containing unsaturated compounds and their borated analogues provide effective multifunctional friction reducing and corrosion inhibiting properties to various lubricating fluids when incorporated therein.

Abstract: Compositions comprising arylboronic acid and substituted arylboronic acid are employed as lubricant additives to impart anti-fatigue properties to metals. In an embodiment, approximately one weight percent of phenylboronic acid added to a polyurea thickened grease containing about two percent of water, results in vastly improved resistance to metal-fatigue failure such as spalling, for example.

Abstract: Mercaptothiadiazole is reacted with hydroxyl-containing unsaturated esters, or their borated derivatives, to yield a product that is useful as a friction reducing additive in lubricants.

Abstract: In preparing organic sulfides by reacting olefins (e.g., butylenes) with a sulfur halide to form a sulfohalogenated intermediate which is subsequently sulfurized and dehalogenated by reaction with an aqueous solution of an alkali metal sulfide compound to form a noncorrosive organic sulfide product of high sulfur content, the copper strip corrosion activity is improved by resulfurizing the sulfurized olefin by contacting it with additional aqueous metal sulfide in the presence of a lower molecular weight alcohol, such as isopropanol.

Abstract: Stable gasoline-alcohol fuel mixtures are produced by hydration of a gasoline or a fraction thereof high in olefins in the presence of an acid catalyst to form a high alcohol content gasoline mixture, which mixture is blended with a gasoline containing up to about 20 volume percent of methanol. The addition of the catalytically hydrated gasoline or olefinic fraction thereof serves to maintain the methanol in complete solution at low temperatures, particularly in the presence of water contaminant.

Abstract: Lubricant compositions containing oleaginous materials and, in amounts sufficient to impart oxidation protection, corrosion resistance and antiwear properties thereto, an adduct of a benzotriazole compound and alkyl vinyl ether or a vinyl ester of a carboxylic acid.

Abstract: Compositions of improved antioxidant characteristics are provided comprising organic media, normally susceptible to oxidation, e.g., oils of lubricant viscosity and greases prepared therefrom containing a minor amount sufficient to impart antioxidant properties thereto of an admixture of a polydisulfide having at least one unit therein with the following structure: ##STR1## WHERE N IS FROM 2 TO ABOUT 20 AND R and R.sub.1 are hydrogen or C.sub.1 -C.sub.10 alkyl; and a compound selected from the group consisting of arylamines and hindered phenols.

Abstract: Novel (N, N-diorganothiocarbamyl) phosphorothioites having the following general structures: ##STR1## and mixtures thereof impart good antiwear and EP properties to lubricant compositions (e.g. gear oils and cutting oils) containing them.

Abstract: Additives that are useful dispersants when placed in lubricants are prepared by (1) reacting an amine or a hydroxy amino compound, such as an amino alcohol, with a halomaleic anhydride and (2) reacting this product with an alkali or alkaline earth metal derivative of a substituted hydroxyaromatic compound.

Abstract: Organic compositions are provided containing anti-rust amounts of esters of adducts of benzotriazole and unsaturated dicarboxylic acids or anhydrides thereof.
