Compressed liquid densities, saturated liquid densities and saturation pressures of mixtures difluoromethane and 1,1,1,2-tetrafluoroethane, difluoromethane and 1,1-difluoroethane.

Author(s) : DEFIBAUGH D. R., MORRISON G.

Summary

The compressed liquid densities and saturation pressures of the mixtures R32-R134a, and R32-R152a have been measured for approximately equal molar mixtures. The liquid densities were measured using a vibrating tube densimeter. The compressed liquid densities for both mixtures are correlated. The saturation pressures were measured using a vapour-liquid-equilibrium variable-volume sapphire cell. The vapour pressures are correlated, and the equations are presented. Saturated liquid densities were calculated by extrapolating compressed liquid isotherms to the saturation pressure. The saturated liquid densities are correlated and the equations are presented.
