1.The system Cu(OH)2-H2O2-H2O has been studied by a solubility method at temperatures of -36°, -20°, 0° and 20°.2.In addition to the peroxidic compound of copper formerly known, CuO2 · H2O, the existence of a new compound with a higher content of active oxygen, CuO2 · H2O2 · H2O has been established, this being formed at higher concentrations of hydrogen peroxide in the liquid phase.3.A polythermal diagram constructed for the temperature range -36° to +20°, giving the limits of equilibrium existence of the solid phases ice, cupric hydroxide, CuO2 · H2O, and CuO2 · H2O2 · H2O, has been obtained.4.The solid phases of peroxide type obtained have been submitted to additional thermal studies. The compound CuO2· H2O2 · H2O has served as a basis for the synthesis of anhydrous cupric peroxide, CuO2. |
