Abstract

A benzene solution of quinone produced by electrolytic oxidation of benzene is subjected to reduction at about the boiling point of benzene under such conditions that the benzene is immediately distilled off and the hydroquinone dissolved in water. For example, the solution may be run into a vessel containing iron borings and water maintained at about 80 DEG C.; benzene distils off and the hot saturated liquors are drawn off, filtered hot and the hydroquinone crystallized out therefrom. Alternatively the quinone-benzene solution may be run into a still containing water into which sulphur dioxide is passed. Benzene distils off and the solution is withdrawn at intervals and acid removed by alkali metal carbonate or hydrate, hydroquinone then being obtained by evaporation. Detailed examples are given.
