Abstract

Antioxidant additives for lubricating oil are prepared by combining ammonium tetrathiomolybdate and a basic nitrogen compound complex to form a sulfur-and molybdenum-containing composition.

Claims

1. A process for preparing a sulfurized molybdenum-containing composition which comprises reacting ammonium tetrathiomolybdate and a basic nitrogen compound selected from the group consisting of a succinimide, carboxylic acid amide, hydrocarbyl monoamine, hydrocarbyl polyamines, Mannich base, phosphonamide, thiophosphonamide, phosphoramide, hydrocarbon dispersant viscosity index improvers, or mixtures thereof.

2. The process of claim 1 wherein said basic nitrogen compound is a C_24-350 hydrocarbyl succinimide, carboxylic acid amide, or a Mannich base prepared from a C_9-200 alkylphenol, formaldehyde, and an amine.

3. The process of claim 2 wherein said basic nitrogen compound is a polyisobutenyl succinimide prepared from polyisobutenyl succinic anhydride and tetraethylene pentaamine or triethylene tetraamine or mixtures thereof.

4. The process of claim 2 wherein said basic nitrogen compound is a carboxylic acid amide prepared from one or more carboxylic acids of the formula R² --COOH wherein R² is C_12-350 alkyl or C_12-350 alkenyl and a hydrocarbyl polyamine.

5. The process of claim 4 wherein R² is C_12-20 alkyl or C_12-20 alkenyl and the hydrocarbyl polyamine is tetraethylene pentaamine or triethylene tetraamine.

6. The process of claim 1 wherein said basic nitrogen compound is a hydrocarbyl polyamine prepared from polyisobutenyl chloride and ethylene diamine, diethylene triamine, triethylene tetraamine or tetraethylene pentaamine or mixtures thereof.

7. The process of claim 2 wherein said basic nitrogen compound is the Mannich base prepared from dodecyl phenol, formaldehyde, and methylamine.

8. The process of claim 2 wherein said basic nitrogen compound is a Mannich base prepared from a C_80-100 alkylphenol, formaldehyde, and triethylene tetraamine or tetraethylene pentaamine or mixtures thereof.

9. The product prepared by the process of claim 1, 2, 3, 4, 5, 6, 7 or 8.

10. A lubricating oil composition comprising an oil of lubricating viscosity and from 0.05 to 15% by weight of the product of claim 9.

11. A lubricating oil concentrate composition comprising an oil of lubricating viscosity and from 15 to 90% by weight of the product of claim 9.
