Vapor-Liquid Equilibrium Data for The System Argon-Oxygen Over the Entire Range of Composition

Abstract

The vapor pressure of certain liquid mixtures of argon and oxygen were measured, and the results were expressed by simple equations. From the data, normal boiling points of the liquid mixtures were computed as well as total pressures at 88.5 deg K. Compositions of the vapor and liquid in equilibrium were measured at one atmosphere total pressure over a wide range of concentration, and "K" values were compiled from the results. The composition of the vapor in equilibrium with the liquid was computed at 88.5 deg K over a wide range of composition. The partial pressures of argon and oxygen over a wide range of liquid composition at 88.5 deg K were found in accord with the Duhem equation. The Duhem equation was used to check the data on the oxygen-nitrogen system.
