Abstract:
1. A lubricating oil composition comprising a lubricating oil in an amount greater than 50% by weight; an oil-soluble secondary diaryl amine, and/or an oil-soluble alkylated phenothiazine; and at least one oil-soluble organo amine tungstate, wherein the at least one organoamine tungstate is prepared by any of the following reactions 1) the reaction of a salt of N-oleyl-1,3-propanediamine with dinonyl naphthalene sulfonic acid and ammonium orthotungstate; 2) the reaction of a salt of N-oleyl-1,3-propanediamine with dinonyl naphthalene sulfonic acid and ammonium paratungstate; 3) the reaction of a salt of N-oleyl-1,3-propanediamine with dinonyl naphthalene sulfonic acid and tungstic acid hydrate derived from the reaction of sodium tungstate dihydrate with acid; 4) the reaction of a salt of N-oleyl-1,3-propanediamine with didodecyl naphthalene sulfonic acid and ammonium paratungstate; 5) the reaction of a salt of N-oleyl-1,3-propanediamine with didodecyl naphthalene sulfonic acid and ammonium orthotungstate; 6) the reaction of a salt of N-oleyl-1,3-propanediamine with didodecyl naphthalene sulfonic acid and tungstic acid hydrate derived from the reaction of sodium tungstate dihydrate with acid; 7) the reaction of a salt of N-oleyl-1,3-propanediamine with naphthenic acid and ammonium paratungstate; 8) the reaction of a salt of N-oleyl-1,3-propanediamine with naphthenic acid and ammonium orthotungstate; 9) the reaction of a salt of N-oleyl-1,3-propanediamine with naphthenic acid and tungstic acid hydrate derived from the reaction of sodium tungstate dihydrate with acid; 10) the reaction of N-oleyl-1,3-propanediamine with canola oil and ammonium paratungstate; 11) the reaction of N-oleyl-1,3-propanediamine with canola oil and ammonium orthotungstate; 12) the reaction of N-oleyl-1,3-propanediamine with canola oil and tungstic acid hydrate derived from the reaction of sodium tungstate dihydrate with acid; 13) the reaction of aminoethyl imidazoline with didodecyl naphthalene sulfonic acid and ammonium paratungstate; 14) the reaction of aminoethyl imidazoline with didodecyl naphthalene sulfonic acid and ammonium ortho tungstate; 15) the reaction of aminoethyl imidazoline with didodecyl naphthalene sulfonic acid and tungstic acid hydrate derived from the reaction of sodium tungstate dihydrate with acid; 16) the reaction of a salt of N-oleyl-1,3-propanediamine with di(2-ethylhexyl) phosphate and ammonium orthotungstate; 17) the reaction of a salt of N-oleyl-1,3-propanediamine with di(2-ethylhexyl) phosphate and ammonium paratungstate; 18) the reaction of a salt of N-oleyl-1,3-propanediamine with di(2-ethylhexyl) phosphate and tungstic acid hydrate derived from the reaction of sodium tungstate dihydrate with acid; 19) the reaction of a salt of N-oleyl-1,3-propanediamine with di(2-ethylhexyl)dithio phosphate and ammonium orthotungstate; 20) the reaction of a salt of N-oleyl-1,3-propanediamine with di(2-ethylhexyl)dithio phosphate and ammonium orthotungstate; and 21) the reaction of a salt of salt of N-oleyl-1,3-propanediamine with di(2-ethylhexyl) dithio phosphate and tungstic acid hydrate derived from the reaction of sodium tungstate dihydrate with acid; 22) the reaction of a salt of N-oleyl-1,3-propanediamine with di(oleyl) phosphate and ammonium orthotungstate; 23) the reaction of a salt of N-oleyl-1,3-propanediamine with di(oleyl) phosphate and ammonium paratungstate; 24) the reaction of a salt of N-oleyl-1,3-propanediamine with di(oleyl) phosphate and tungstic acid hydrate derived from the reaction of sodium tungstate dihydrate with acid.
