A dialkylanilino-cyclohexane compound useful as an antioxidant has the following formula (I) or formula (I): wherein Ar1 and Ar2 can be the same or different and each is an alkylaromatic group; each of R1, R2, R3, and R4 is independently selected from hydrogen or CR7R8; each of R5, R6 , and R7 is independently selected from hydrogen and a substituted or unsubstituted C1 to C32 hydrocarbyl group; and each R8 is independently selected from hydrogen and a C1 to C2 alkyl group, provided that when, each of R1 and R2 is CR7R8 and each such R8 is other than hydrogen, R1 and R2 may be joined to form a five or six-membered ring, and provided further that when, each of R3 and R4 is an adjacent CR7R8 and each such R8 is other than hydrogen, R3 and R4 may be joined to form a five or six-membered ring.
一种作为抗氧化剂有用的二烷基苯胺基环己烷化合物具有以下化学式(I)或化学式(I):其中Ar1和Ar2可以相同也可以不同,每个都是烷基芳基基团;R1、R2、R3和R4中的每一个可独立地选择为氢或CR7R8;R5、R6和R7中的每一个可独立地选择为氢和取代或未取代的C1至C32烃基基团;每个R8可独立地选择为氢和C1至C2烷基基团,但当R1和R2中的每一个均为CR7R8且每个R8均为非氢时,R1和R2可以连接以形成五元或六元环,进一步提供当R3和R4中的每一个为相邻的CR7R8且每个R8均为非氢时,R3和R4可以连接以形成五元或六元环。
