ABSTRACT:
Provided are compounds of formulawherein R1is linear or branched alkyl; AR is phenyl, naphthyl, or phenanthryl; and m is 0, 1, or 2; and R2is an alkyl substituted carboxyl. Lubricating oils comprising a polyol ester lubricant in combination with one or more compounds of Formula I are also provided. Compounds having structures of Formula I are formed by mixing N-4-alkylphenyl-1-naphthylamine, paraformaldehyde, glacial acetic acid, and a polyol ester base lubricant and heating and stirring the mixture to cause a condensation reaction. Water and acetic acid are subsequently removed, thereby providing the compound of formula I in the polyol ester base lubricant.
