The preparation of ozone by electrolysis II

Some improvements in the design of the previously described electrolytic ozone generator are described. These make the apparatus easier to construct and to handle; in addition, the ozone percentage and production are increased, amounting to 15½ % by weight and 14½ mmols/hr at 15 A, and to 15% by weight and 17 mmols/hr., respectively, at 18 A. By stabilization of the electrolyzing current the apparatus has been shown to be highly satisfactory for quantitative purposes. A stabilizer is described by which the composition of the ozone‐oxygen mixture can be kept constant within a few units per mille for several hours. An apparatus capable of producing smaller amounts of high‐percentage ozone, for use at low current strength, without the need of internally cooling the anode, is also described.
