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.
L'invention porte sur une phénylènediamine substituée par cycloalkyle en C5-C12 qui fournit des additifs anticalaminants pour lubrifiants, appropriés pour des matières organiques comprenant une huile lubrifiante, de l'essence et des carburants diesel. L'invention permet d'améliorer la stabilité oxydante des lubrifiants et des combustibles par l'addition de phénylènediamines substituées par cycloalkyle ayant un ou plusieurs N-substituants supplémentaires.
