Abstract
Quinones are produced by electrolysis of corresponding hydroquinones, in the anode compartment of an electrolytic cell, by electrolyzing a dispersion or emulsion including a conductive aqueous solution of hydroquinone and at least one stable cosolvent which is poorly soluble in water but which is a good solvent for the quinone produced and a poor solvent for the hydroquinone.
