Abstract: Diaryl amines are selectively alkylated by reaction with branched olefins, which olefins are capable of forming tertiary carbonium ions and can be conveniently prepared from readily available branched alcohols. The diaryl amine products are effective antioxidants and often comprise a high amount of di-alkylated diaryl amines and a low amount of tri- and tetra-alkylated diaryl amines.

Abstract: Certain alkylated 3-hydroxyphenylamine antioxidants wherein one phenyl is substituted by at least one hydroxyl group at the 3-position relative to the amine and the other phenyl is substituted by at least one substituent having 4 or more carbon atoms are surprisingly effective antioxidants, especially in lubricating oils.
