    Abstract: A process for preparing 3,5-dialkyl phenols is provided. In one embodiment an ortho-, para-, or meta-monoalkyl phenol is caused to isomerize and/or disproportionate to the 3,5-dialkyl phenol in reaction medium comprising liquid hydrogen fluoride. In another embodiment the 3,5-dialkyl phenol is obtained by contacting phenol with an alkylating agent selected from tertiary alcohols, tertiary alkyl halides, and olefins in a reaction medium comprising liquid hydrogen fluoride.
