Abstract:
The data needed for analysis of liquid ozone-oxygen mixtures by measurement of magnetic susceptibility are presented. Volumetric preparation of liquid ozone-oxygen mixtures in equilibrium with the vapor phase is described. A permanent magnet at the temperature of the solutions provided the key for use of the Quincke (U-tube) method for magnetic susceptibility. Results at — 195° and — 183°C show a linear relation between the magnetic susceptibility of the solutions and weight percent oxygen at low oxygen content. Above about 10 percent oxygen the specific susceptibility of oxygen in solution decreases significantly. At — 183°C, the ratio X8/X0 of specific susceptibility of oxygen in solution to that of pure liquid oxygen decreased from 1.30 at low concentrations to 1.13 at 27.6 percent oxygen, the two-liquid phase boundary. The limiting ratio at — 195°C was 1.42. The discontinuity in magnetic susceptibility was used to establish the compositions at the phase boundaries; 9.2 and 91 percent by weight oxygen at — 195°C, 27.6 and 70.2 percent at — 183°C.
