ABSTRACT:
Phenolic imidazolines prepared via one-step condensation of hydrocarbylpolyamino-phenols and carbonyl generating species have been found to be effective antioxidants in lubricant applications. These additives are derived from a one-step reaction using low cost phenolic amines and carbonyl compounds. In addition to their antioxidant activity, they are, because of the presence of the cyclic imidazoline groups, also expected to exhibit corrosion inhibiting and metal passivating activity.
