Abstract:
Nickel (II) thiobis(alkylphenolate) complex with thiobis(alkylphenol) forms novel complexes having improved antioxidant properties which are useful in a wide range of organic media such as lubricants and plastics. These novel complexes also provide energy quenching characteristics to such organic compositions.
Abstract:
A direct exchange process wherein compounds are prepared by replacing calcium in neutral and overbased calcium phenol sulfides with transition metals by reaction with transition metal salts in the presence of an accelerator or promoter provides useful stabilizer-detergent additives for lubricating compositions.
Abstract:
N-alkoxyalkyl amides may be formed by the reaction of primary alkoxyalkylamines with carboxylic acids such as formic acid, or alternatively by ammonolysis of the appropriate formate ester. The resultant amides exhibit friction reducing properties when incorporated in additive amounts in lubricants and fuels. Extremely low concentrations of such additives, i.e. N-alkoxyalkyl formamides in lubricating oils result in vastly improved, i.e. lowered coefficients of friction. By virtue of the friction reducing characteristics and lubricity properties, the additive compositions of the present invention exhibit reduced wear on rubbing surfaces.
Abstract:
Lubricant compositions containing minor effective amounts of calcium phenol sulfides containing controlled amounts of a transition metal wherein the transition metal is derived by a direct exchange reaction for calcium provide stabilizer/detergent properties thereto and protect the compositions thereof against oxidative deterioration.
Abstract:
Phenol sulfides, disulfides, polysulfides and oligomers thereof when reacted with alkyl vinyl ethers provide addition products substantially comprised of novel acetal derivatives which are effective oxidation inhibitors when incorporated into organic media normally susceptible to oxidative degradation.

Abstract:
New reaction products obtained by reacting (1) a hindered phenol, (2) a boron compound and (3) an amine together are described. Preferred reaction sequences are:(a)(2)+(1), then this product with (3); and(b)(2)+(3), then this product with (1).Also described are lubricant compositions containing the reaction products and a method of reducing fuel consumption in an internal combustion engine by lubricating the engine with a lubricant containing the reaction product.
