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.

Phenol purification process

A method for producing an alkylated aromatic compound includes a step (i) of producing a reaction product (a1) containing the alkylated aromatic compound and water by the reaction of an aromatic compound, a ketone, and hydrogen using a metal component containing at least one metallic element of copper, nickel, cobalt, and rhenium and a solid acid substance; a step (ii) of forming a dehydrated product (a2) from at least a portion of the reaction product (a1) by removing at least a portion of the water in the reaction product (a1); and a step (iii) of producing a reaction product (a3) containing the alkylated aromatic compound by bringing at least a portion of the dehydrated product (a2) into contact with a solid acid substance.
