Abstract: An oil additive consists of a complex of at least two "metal compounds" as defined, having dissimilar metals, coupled with one or more non-metallic organic compounds of the formula R2X or R3Y or [R-X]3Z, where R is a substituted or unsubstituted alkyl, cycloalkyl, alkenyl or aryl group, X is an oxygen, sulphur, selenium or tellurium atom, Y is a phosphorus, arsenic or antimony atom, and Z is a phosphorus, arsenic or antimony atom.  The "metal compounds" are the inorganic and organic compounds, other than petroleum sulphonates, of the metals of the right-hand columns of Groups 1 to 4 and of the metals of Groups 6 to 8.  The organic radicals present may contain such substituents as halogen, NH2, NO2, NO, N = NO, CN, SCN, OH, SH, SeH, TeH, SO3H, and CXXH where X is O, S, Se or Te.  Metal compounds include Cu, Sn, Ag. Zn, Mn, Cd, Hg, Ni, Co, Fe, and Al fluorides, chlorides, bromides, azides, thiocyanates, sulphates, carbonates, xanthogenates, fatty acid salts, phenates or alcoholates.  The non-metallic organic compounds may be phosphites, phosphines, arsines, arsenites, sulphides, selenides, tellurides, stibines or antimonites.  Examples describe the formation of the following complexes by stirring the components in various molar ratios, sometimes in a nitrogen atmosphere, at temperatures from room up to 180 DEG  C.: tributyl phosphite-stannous chloride-cuprous chloride, cupric fluoride or silver chloride; tributyl phosphite-silver chloride-cuprous chloride; tributyl phosphite-manganous chloride - silver chloride, cupric bromide or cuprous iodide; tributyl phosphite-cobaltous chloride-stannous chloride-cuprous bromide or manganous chloride; and cuprous chloride-stannous chloride-tributyl arsenite or antimonite. Numerous other examples include complexes containing metal acetyl acetone, urea, phenol, amide, amine, cyclopentadiene, fatty acid, and mercaptan compounds, and complexes with more than one non-metallic organic compound.  The complexes may be prepared in solution in a solvent such as a lubricating oil.  They are added to base oils, either natural or synthetic, generally in amounts of a fraction of 1 to 15 per cent, to grease compositions comprising soaps, and to damping and hydraulic fluids, insulating oils, heat transfer media, coating compositions, and insecticides. Other additives include detergents, antioxidants, corrosion inhibitors, extreme pressure agents, urea or thiourea derivatives, and oil-soluble polymers.ALSO:An oil additive consists of a complex of at least two "metal compounds" as defined, having dissimilar metals, coupled with one or more non-metallic organic compounds of the formula R2X or R3Y or [R-X]3Z, where R is a substituted or unsubstituted alkyl, cycloalkyl, alkenyl or aryl group, X is an oxygen, sulphur, selenium or tellurium atom, Y is a phosphorus, arsenic or antimony atom, and Z is a phosphorus arsenic or antimony atom.

Examples describe the formation of the following complexes: tributyl-phosphite-stannous chloride-cuprous chloride, cupric fluoride or silver chloride; tributyl phosphite-silver chloride-cuprous chloride; tributyl phosphite-manganous chloride-silver chloride, cupric bromide or cuprous iodide; tributyl phosphite-cobaltous chloride-stannous chloride-cuprous bromide or manganous chloride; and cuprous chloride-stannous chloride-tributyl arsenite or antimonite.

The complexes may be prepared in solution in a solvent such as lubricating oil.  They are added to base oils either natural or synthetic, e.g. polymers of hydrocarbons or alkylene glycols and alkylene oxides, tetrahydrofuran or silicones, esters, particularly of dibasic acids, H2S adducts of ethers and thioethers, or mixtures which may contain fixed oils such as castor or lard, generally in amounts of a fraction of 1 per cent to 15 per cent, and to grease compositions comprising soap, preferably alkali or alkaline earth, lead, and aluminium soaps of fatty acids or their glycerides or such gelling agents as silica or alumina gels or colloidal carbon, and to damping and hydraulic fluids, insulating oils, heat-transfer media, coating compositions and insecticides. Other additives include detergents, antioxidants, corrosion inhibitors, and extreme pressure agents, e.g. salts of inorganic or organic bases with detergent-forming acids, phenols and phenol sulphides, alkaline earth phosphate or thiophosphate diesters, alkali salts of alkyl phenol-aldehyde condensation products, alkyl phenols, aminophenols and amines, dicarboxylic acids, alkali and alkaline earth salts of sulphonic and fatty acids, CN, NO2 or NO derivatives of acidic compounds, esters of phosphorus acids, aromatic sulphides, sulphurized oils and olefins, sulphurized phosphorized oils or fatty acids, phosphorus acid esters of sulphurized acids, chlorinated hydrocarbons and esters, urea or thiourea derivatives, and oil-soluble polymers.ALSO:Insecticidal compositions comprise a complex of at least two "metal compounds" as defined, having dissimilar metals, coupled with one or more non-metallic organic compounds of the formula R2X or R3Y or [R-X]3Z, where R is a substituted or unsubstituted alkyl, cycloalkyl, alkenyl or aryl group, X is an oxygen, sulphur, selenium or tellurium atom, Y is a phosphorous, arsenic or antimony atom, and Z is a phosphorus, arsenic or antimony atom.
