ABSTRACT:
A process is provided for converting waste distillation bottoms containing t-alkylphenols with substantial unknown constituents to useable para-t-alkylphenols. The process comprises heating the waste distillation bottoms with phenol and an acid catalyst to effect transalkylation. The waste distillation bottoms typically result from the production of para-t-alkylphenol and/or 2,4-di-t-alkylphenol.
