Patent number: 11046906Abstract: A lubricant composition includes a base oil present in an amount of greater than 70 parts by weight per 100 parts by weight of the lubricant composition and an antioxidant. The antioxidant has the structure: wherein each X is independently C-A or N, so long as at least one X is N but no more than two of X are N. Moreover, A is H, cyano or an electron donating group that: (1) has an atom having at least one lone pair of electrons that is bonded directly to the aromatic ring; or (2) is an aryl group or alkyl group. Further, each R is independently H, an alkyl group, or aryl group and each R? is independently an alkyl group or an aryl group.Type: GrantFiled: April 23, 2020Date of Patent: June 29, 2021Assignee: BASF SEInventors: Philippe Rabbat, Mary Elizabeth Dery, Bridgett Rakestraw, Sai P. Shum, Paul Angelo Odorisio
