Substituted 1-aminonaphthalenes of formula I
wherein n is 1-3, Ar is arylene, R₁ and R₂ are independently hydrogen, alkyl or phenyl, R₃ is hydrogen, alkyl or substituted alkyl, and R₄ and R₅ have independently the same definitions as R₃ or are independently aryl, substituted aryl or cycloalkyl, are effective stabilizers for lubricating oil or polymer compositions. The instant compounds are particularly effective in lubricating oil compositions when used with a diarylamine antioxidant.
式 I 的取代 1-氨基萘
其中 n 为 1-3,Ar 为芳基烯,R₁ 和 R₂ 独立地为氢、烷基或苯基,R₃ 为氢、烷基或取代烷基,R₄ 和 R₅ 独立地具有与 R₃ 相同的定义或独立地为芳基、取代芳基或环烷基,是润滑油或聚合物组合物的有效稳定剂。当与二芳基胺抗氧化剂一起使用时,本化合物在润滑油组合物中尤其有效。
