HIGH MOLECULAR WEIGHT IMIDE CONTAINING QUATERNARY AMMONIUM SALTS

摘要

The present technology is related to imide containing quaternary ammonium salts having a hydrocarbyl substituent of number average molecular weight of 1300 to 3000, and the use of such quaternary ammonium salts in fuel compositions or lubricating compositions to improve the water shedding performance of the fuel or lubricant composition.

主权项

1. A composition comprising an imide containing quaternary ammonium salt (“imide quat”), wherein the imide quat comprises the reaction product of:
a) a quaternizable compound that is the reaction product of:
(i) a hydrocarbyl-substituted acylating agent, wherein the hydrocarbyl-substituent has a number average molecular weight ranging from 1300 to 3000, and(ii) a nitrogen containing compound having a nitrogen atom capable of reacting with said hydrocarbyl-substituted acylating agent to form an imide, and further having at least one quaternizable amino group; and b) a quaternizing agent suitable for converting the quaternizable amino group of the nitrogen containing compound to a quaternary nitrogen.
