HETEROCYCLIC COMPOUNDS USEFUL AS ADDITIVES FOR LUBRICANT AND FUEL COMPOSITIONS

摘要

Various heterocyclic compounds have been discovered that impart improved fuel economy and friction modification to lubricant and fuel compositions. These heterocyclic compounds of the invention preferably contain nitrogen and may be further reacted with hydrocarbyl carboxylic acid acylating reactants or hydrocarbyl phenolic reactants to give higher molecular materials. These higher molecular weight materials have higher oil-solubility and impart dispersancy properties to lubricant and fuel compositions.
