THE VISCOSITY OF VAPOR MIXTURES OF HYDROGEN PEROXIDE AND WATER

Abstract

The viscosity of vapor mixtures of H2O2 and H2O containing up to 65 mol-%H2O2 was measured by a capillary flow method at 1 atm total pressure and a temperature of 170 deg C. The viscosity of anhydrous H2O2 vapor at 170 deg C was found to be 144 micropoises by extrapolation. Studies were also made at 200 deg and 240 deg C to provide a basis for estimating the effect of temperature. An all-glass apparatus made it possible to produce vapors containing less than 1 mol-% of O, and it was demonstrated that this low O concentration did not affect the precision of measurement. The viscosity was found to be represented by the equation, micron = 134 + 0.35 (t - 100) - 14y where micron is the viscosity in micropoises, t is the temperature in deg C, and y is the composition in mole fraction H2O2. This equation is recommended for the calculation of the viscosity of vapor mixtures of H2)2 and H2O over the temperature range of 100 to 300 deg C, and is believed to have a precision of within + or - 2%. The results provide a measure of the viscous forces in a highly polar gaseous system.
