HYDROGEN PEROXIDE AND ITS ANALOGUES: I. DENSITY, REFRACTIVE INDEX, VISCOSITY, AND SURFACE TENSION OF DEUTERIUM PEROXIDE – DEUTERIUM OXIDE SOLUTIONS

Abstract

Some deuterium peroxide containing less than 0.3% ordinary hydrogen was produced both by the persulphate and the electric discharge methods. By means of fractional distillation, solutions of deuterium peroxide in deuterium oxide of various concentrations up to 90% were obtained, of which the following properties were measured: refractive index at 25°C, density, viscosity and surface tension at 0°C. and 20°C. Measurements of the last two properties were also extended to solutions of ordinary hydrogen peroxide. The physical constants of the two isotopic peroxides are compared and discussed. The density, viscosity and surface tension of supercooled heavy water at 0°C. were also measured for the first time.
