Abstract

Thirty-six saturated liquid densities of HCFC 142b (1-chloro-1,1-difluoroethane) were measured in a range of temperatures from 210 to 400 K. Twelve vapor pressures, from 320 to 400 K, and six compressed liquid PVT properties, from 320 to 360 K and of pressures up to 2 MPa, were also measured. All measurements were made by a magnetic densimeter coupled with a variable volume cell. The experimental uncertainties in temperature, pressure, and density were estimated to be not greater than ±15 mK, ±10 kPa, and ±0.2%, respectively. The purity of the sample used was 99.8 wt % or better. The simple correlation for the saturated liquid density of HCFC 142b was developed.
