摘要
Process technology is described for producing a reaction-derived product mixture containing a high yield of octylated phenyl-alpha-naphthylamine by catalytic alkylation of phenyl-alpha-naphthylamine with diisobutylene. New reaction-derived product mixtures are produced. Also provided are novel reaction-derived octylated phenyl-alpha-naphthylamine reaction product mixtures from which catalyst residues and excess olefin components have been removed. These reaction product mixtures are effective as antioxidants for various oxygen-sensitive substrate materials such as oils and lubricants. Also described are new octylated phenyl-alpha-naphthylamine product mixtures and their use in forming clear, stable, liquid antioxidant compositions for addition to a wide variety of substrates.
