Abstract

Measurements of the surface tension for two kinds of CFC alternatives, i.e., HCFC-123 (2,2-dichloro-1,1,1-trifluoroethane), and HFC-134a (1,1,1,2-tetrafluoroethane), have been made by the differential capillary rise method (DCRM) and the vertical plate method (VPM). For HCFC-123, 15 data have been obtained by DCRM in the temperature range between 273 and 333 K within the uncertainty of ±0.1mN/m, and 21 data have been obtained by VPM in the temperature range between 273 and 290 K within the uncertainty of ±0.2mN/m. For HFC-134a, 17 data have been obtained by DCRM in the temperature range between 276 and 329 K within the uncertainty of ±0.1mN/m. The uncertainty of temperature measurement by DCRM is estimated within ±20mK, whereas that by VPM within ±30mK. New correlations of the surface tension for HCFC-123 and HFC-134a have been also proposed.
