Abstract
The transient formation of para-benzoquinone during the hydroxylation of phenol by hydrogen peroxide over solid acids is investigated. Formed by overoxidation of hydroquinone, para-benzoquinone is involved in an acid catalysed redox process responsible for the autocatalysis of the reaction and for a partial decomposition of hydrogen peroxide into oxygen and water.
