Abstract

A quaternary ammonium salt detergent made from the reaction product of the reaction of: (a) polyalkene-substituted amine having at least one tertiary amino group; and (b) a quaternizing agent suitable for converting the tertiary amino group to a quaternary nitrogen and the use of such quaternary ammonium salt detergents in a fuel composition to reduce intake valve deposits.

First claim

What we claim:

1. A composition comprising a quaternary ammonium salt which comprises the reaction product of:
a. polyalkene-substituted amine having at least one tertiary amino group; and
b. quaternizing agent suitable for converting the tertiary amino group to a quaternary nitrogen,

wherein the quaternizing agent is a hydrocarbyl epoxide, as represented by formula (IX), in combination with an acid

wherein R 1, R 2, R 3, and R 4 can be independently H or a C 1-50 hydrocarbyl group; and
wherein the polyalkene-substituted amine has a number average molecular weight of about 500 to about 3000 and is derived from a polyisobutylene.

2. The composition of claim 1 , further comprising a fuel which is liquid at room temperature.

3. The composition of claim 1 , further comprising a fluidizer.

4. The composition of claim 1 , further comprising an oil of lubricating viscosity.

5. The composition of claim 4 , further comprising component selected from the group consisting of metal deactivators, detergents other than those of claim 1 , dispersants, viscosity modifiers, friction modifiers, dispersant viscosity modifiers, extreme pressure agents, antiwear agents, antioxidants, corrosion inhibitors, foam inhibitors, demulsifiers, pour point depressants, seal swelling agents, wax control polymers, scale inhibitors, gas-hydrate inhibitors and mixtures thereof.

6. The composition of claim 5 , wherein the component is an overbased metal containing detergent, zinc dialkyldithiophosphates or mixtures thereof.

7. A method of fueling an internal combustion engine comprising:
A. supplying to said engine:
i. a fuel which is liquid at room temperature; and
ii. the composition of claim 1 .

8. A method of lubricating an internal combustion engine comprising:
A. supplying to the crankcase of said engine:
i. an oil of lubricating viscosity; and
ii. the composition of claim 1 .

9. A composition comprising: (i) a particulate solid; (ii) an organic medium; and (iii) the composition of claim 1 .

10. The composition of claim 9 , wherein the organic medium is an organic liquid or a plastics material.

11. The composition of claim 10 , wherein the organic liquid comprises at least 0.1% by weight of a polar organic liquid based on the total organic liquid.

12. The composition of claim 9 , wherein the particulate solid is a pigment.

13. A paint or ink composition comprising a particulate solid, an organic liquid, a binder and the composition of claim 1 .

14. A mill-base comprising a particulate solid, an organic liquid and the composition of claim 1 .
