Abstract

Disclosed is an additive for liquid hydrocarbon fuel composition, particularly diesel fuels. The additive composition is the reaction product of polyalkenyl-substituted succinimides, aldehydes, and triazoles. It also finds use in lubricant compositions.

Claims

1. An improved lubricant composition comprising a major proportion of an oil of lubricating viscosity or a grease prepared thereof and between about 0.1% and 10% by weight of the total composition of a multifunctional detergent/dispersant/antioxidant reaction product obtained by reacting a polyalkenyl-substituted succinimide having the structural formula:

##STR4## where R is an alkyl or alkenyl or alkenyl group of 9 to 150 carbon atoms with a triazole having the structural formula;

##STR5## where R¹ is hydrogen or an alkyl, aryl, arylalkyl, or alkylaryl group of 1 to 12 carbon atoms with an aldehyde wherein the polyalkenyl-substituted succinimide, aldehyde and triazole are reacted in a mole ratio of succinimide to aldehyde to triazole respectively of between about 1 to 0.1 to 0.1 and about 1 to 4 to 4 at temperatures varying from about 100°

C. to about 200°

C. at ambient pressures.

2. The composition of claim 1 wherein the polyalkenyl-substituted succinimide is a polyisobutenyl succinimide.

3. The composition of claim 1 wherein the triazole is tolyltriazole.

4. The composition of claim 1 wherein the reaction product has the structural formula:

##STR6## where R is an alkyl or alkenyl group of 9 to 150 carbon atoms,, R¹ and R² are each hydrogen or an alkyl, aryl, arylalkyl, alkylarlyl group of 1 to 12 carbon atoms, y is greater than 0, and x+y is equal to 1 to 4.

5. The composition of claim 1 wherein the reaction is conducted in a carrier solvent selected from the group consisting of xylene and toluene.

6. A method for making a lubricant composition comprising adding to a lubricant between about 0.1% and about 10% by weight of the total composition of the reaction product described in claim 1.

7. The composition of claim 1 wherein the aldehyde is selected from the group consisting of formaldehyde, paraformaldehyde, benzaldehyde, salicylaldehyde, and 2-ethylhexanal.

8. The composition of claim 7 wherein the aldehyde is formaldehyde.

9. The composition of claim 1 wherein the oil of lubricating viscosity is selected from (1) mineral oils, (2) synthetic oils or (3) a mixture of (1) and (2) or (4) a grease prepared from any one of (1), (2) or (3).

10. The composition of claim 9 wherein the oil of lubricating viscosity is (1) a mineral oil.

11. The composition of claim 9 wherein the oil of lubricating viscosity is (2) a synthetic oil.

12. The composition of claim 9 wherein the oil of lubricating viscosity is (3) a mixture of (1) and (2).

13. The composition of claim 9 comprising a grease.
