ABSTRACT:
An aromatic compound selected from benzene and biphenyl compounds containing at least one isopropyl group is oxidized to convert at least one of the at least one isopropyl group into a 2-hydroxy-2-propyl group. The oxidation of the aromatic compound is effected with molecular oxygen in the presence of an aqueous alkali solution in an oxidative reaction vessel made of nickel at parts thereof where the vessel comes into contact with a reaction mixture. In particular, the above process suppresses the formation of by-products and permits long-term oxidation on an industrial scale.
