METHOD FOR PURIFYING PHENOL

摘要

In this method for purifying phenol carbonyl compounds in the phenol are converted into the corresponding alcohol compounds by selective hydrogenation and readily separated from the phenol by distillation. This method for purifying phenol is characterized in that phenol is brought into contact with a copper based catalyst in the presence of hydrogen and the carbonyl compounds in the phenol are each converted into the corresponding alcohol compounds and then separated from the phenol by distillation.
