ABSTRACT:
A method and apparatus for producing hydrogen peroxide in caustic solution utilizing an electrolytic cell having two electrolytes, one acidic, one basic, separated by a membrane permeable to positive ions. Electrolysis of oxygen which diffuses through a gas-diffusion cathode forms peroxide in caustic catholyte while hydrogen ions generated at an anode are allowed to migrate into the catholyte by the membrane. Peroxide produced in the catholyte upon circulation of catholyte in the cell a product can be produced having a caustic to peroxide ratio of less than 1.0 at five percent peroxide, by weight.
