Phenols having an unsubstituted ortho position are transalkylated in the ortho position by mixing them with an ortho-alpha-branched alkylphenol (e.g., 2,6-di-sec-butylphenol) and an aluminum phenoxide catalyst and heating the mixture to 100°-350°C., preferably in a closed system and in the presence of olefin corresponding in structure to the ortho-alpha-branched alkyl group.
