摘要:
Monoaryltrialkyl phenylenediamine compounds useful as ashless TBN sources for lubricating oil compositions that are compatible with fluoroelastomeric engine seal materials and meet copper corrosion requirements, and lubricating oil compositions containing such phenylenediamine compounds.
摘要:
The invention is a C5-C12 cycloalkyl substituted phenylenediamine that provides deposit-control lubricant additives for organic materials including lubricating oil, gasoline, and diesel fuels. The invention improves the oxidative stability of the lubricants and fuels by adding cycloalkyl substituted phenylenediamines having one or more additional N-substituents.
