Claims
- 1. An additive composition for lubricating oils comprising an inorganic acid and a reaction product resulting from reacting a non-metallic dihydrocarbylaromatic sulfonate compound having a nitrogen containing moiety selected from the group consisting of alkanolamine salts, polyalkenylene diamines, etheral diamines, aryldiamines, diaryldiamines, and alkylated diamines or a monohydrocarbylaromatic sulfonate compound having a nitrogen containing moiety the group consisting of ammonium, amines, alkanolamine salts, and alkylated amines and a dihydrocarbyl or trihydrocarbyl phosphite in a mole ratio of sulfonate compound to phosphite compound of between about 10:1 and about 1:10 at a temperature between about 60.degree. C. and about 200.degree..
- 2. The additive composition of claim 1 wherein the non-metallic dialkylnaphthalene sulfonate compound is an ammonium salt.
- 3. The additive composition of claim 1 wherein the non-metallic dihydrocarbylaromatic sulfonate compound is ammonium dinonylnaphthalene sulfonate.
- 4. The additive composition of claim 1 wherein the dihydrocarbyl or trihydrocarbyl phosphite has the structural formula
- (R.sub.1 O).sub.2 POR.sub.2
- where R.sub.1 is a hydrocarbon radical of 1 to 18 carbon atoms and R.sub.2 is hydrogen or a hydrocarbon radical of 1 to 18 carbon atoms.
- 5. The additive composition of claim 1 wherein the dihydrocarbyl or trihydrocarbyl phosphite is selected from the group consisting of oleyl, phenyl, nonyl phenyl, octylphenyl, 2-ethyl hexyl, 1,3-dimethylbutyl, tridecyl, isodecyl, octyl, and butyl, and mixed phosphites thereof.
- 6. The additive composition of claim 1 wherein the acid is sulfuric acid.
- 7. A lubricant composition comprising a hydrocarbon lubricant and between about 0.01% and about 10% by weight of the total composition of the reaction product of claim 1.
- 8. A lubricant composition comprising a hydrocarbon lubricant and between about 0.01% and about 10% by weight of the total composition of the reaction product of claim 2.
- 9. A lubricant composition comprising a hydrocarbon lubricant and between about 0.01% and about 10% by weight of the total composition of the reaction product of claim 3.
- 10. A lubricant composition comprising a hydrocarbon lubricant and between about 0.01% and about 10% by weight of the total composition of the reaction product of claim 5.
- 11. A lubricant composition comprising a hydrocarbon lubricant and between about 0.01% and about 10% by weight of the total composition of the reaction product of claim 6.
- 12. A method for making a lubricant composition comprising adding to a hydrocarbon lubricant between about 0.01% and about 10% by weight of the total composition of the additive composition of claim 3.
