Method of making hydrogen peroxide

A method of preparing hydrogen peroxide by forming peroxide by the reduction of oxygen, which includes the steps of:

• preparing an electrolyte solution containing in dissolved form an organic compound adapted to form a redox system, introducing oxygen into said electrolyte solution, passing current through said electrolyte solution by means of an anode and cathode to thereby reduce the oxidized form of the organic compound on acid cathode and form the reduced form of said organic compound, reducing the oxygen introduced into said electrolyte solution by reacting said last mentioned oxygen with the thus reduced form of said organic compound while at the same time re-generating the oxidized form of said organic compound and forming peroxide, subsequently for separating out said formed peroxide adding to said electrolyte solution such a quantity of an alkaline earth metal compound selected from the group consisting of alkaline earth metal hydroxide, alkaline earth metal oxide, and alkaline earth metal salt, that the peroxide is precipitated as alkaline earth metal peroxide, subsequently filtering off said precipitated alkaline earth metal peroxide and withdrawing the same from said electrolyte solution, suspending the thus obtained alkaline earth metal peroxide in water, introducing acid into the thus formed suspension to thereby by reaction of said alkaline earth metal peroxide with said acid form hydrogen peroxide, and subsequently separating said hydrogen peroxide from said solution.
