ABSTRACT:
A method of and electrolytic cell for making hydrogen peroxide, according which oxygen is introduced into an electrolyte solution which contains in dissolved form an organic compound forming a redox system. After reduction of the oxidized form of the organic compound on the cathode of the electrolytic cell, which preferably has a cathode of glass-like carbon or graphite, and which is passed through by the current and after formation of the reduced form of the organic compound, the oxygen introduced into the electrolyte solution is reduced by reaction with the thus obtained reduced form of the organic compound. With a simultaneous re-formation of the oxidized form of the organic compound, peroxide is formed whereupon there is introduced into the electrolyte solution for separating the formed peroxide such a quantity of an alkaline earth metal compound that the peroxide is precipitated as alkaline earth metal peroxide and the precipitated alkaline earth metal peroxide is filtered off and withdrawn from the electrolyte solution, whereupon it is suspended in water, and acid is introduced into the thus formed suspension so that by reaction of the alkaline-peroxide with the acid hydrogen peroxide is formed.
