Phase equilibria behavior of the systems carbon dioxide + n-dotriacontane and carbon dioxide + n-docosane

The phase behavior of the binary mixture carbon dioxide + n-dotriacontane was studied as a vapor-liquid system at 75, 100, and 125/sup 0/C and along the high-temperature branch of its solid-liquid-vapor locus to pressures of 1050 psia. The phase behavior of the binary mixture carbon dioxide + n-docosane was studied as a vapor-liquid system at 50, 75, and 100/sup 0/C and along the high-temperature branch of its solid-liquid-vapor locus to pressures of 1050 psia. The studies were carried out in a visual cell apparatus recently constructed by the investigators. The apparatus is described in detail herein. Properties of the systems reported are pressure, temperature, liquid-phase composition, and liquid-phase molar volume.
