Abstract

The isobaric heat capacity, Cp, of HCFC-123 which is a prospective alternative to CFC-11 has been measured by using a flow-calorimeter in the liquid phase. Sixty-nine Cp values have been determined at temperatures from 276 K to 410 K and pressures from 0.5 MPa to 3.0 MPa. The uncertainty was estimated being within ± 10 mK in temperature, ±2 KPa in pressure and ±0.4 % in Cp, respectively. A Cp correlation which is effective in the experimental range has been also developed.
