Abstract

Yokoyama, C. and Takahashi, S., 1991. Saturated liquid densities of 2,2-dichloro-1,1,1-triflu-oroethane (HCFC-123), 1,2-dichloro-1,2,2-trifluoroethane (HCFC-123a), 1,1,1,2-tetrafluo-roethane (HFC-134a) and 1,1,1-trifluoroethane (HFC-143a). Fluid Phase Equilibria, 67: 227-240. Saturated liquid densities of 2,2-dichloro-1,1,1-trifluoroethane (HCFC-123), 1,2-dichloro-1,2,2-trifluoroethane (HCFC-123a), 1,1,2-tetrafluoroethane (HFC-134a) and 1,1,1-trifluoro-ethane (HFC-143a) were measured with a pressurized pycnometer at several temperatures. The low-temperature limits of the measurements were about 250 K for all four compounds. The high-temperature limits were 423 K for HCFC-123, 420 K for HCFC-123a, 367 K for HFC-134a and 341 K for HFC-143a. The experimental results were fitted successfully with the Pentermann-Wagner-type equation. The liquid density correlations of Yen-Woods, Spencer-Danner and Hankinson-Thomson were used to correlate the experimental data.
