Abstract
The present invention provides an easy process for purifying phenol by separating carbonyl compounds through selective hydrogenation of the compounds to the corresponding alcohols then distillation. The phenol purification process of the present invention comprises bringing phenol into contact with a copper-based catalyst in the presence of hydrogen to convert carbonyl compounds contained in the phenol to the corresponding alcohol compounds, and separating the alcohol compounds and phenol by distillation.
