HCFC123, HFC134a, CFC11及びCFC12の飽和液体密度

抄録

The saturated liquid densities of two environmentally acceptable hydrogen-containing halocarbons (HCFC123 and HFC134a) and two fully halogenated chlorofluorocarbons (CFCl1 and CFC12) were determined experimentally. The measurement has been conducted by the method using pyrex glass floats.
Eleven saturated liquid densities were obtained in the range of temperature from 281 to 352 K for HCFC123. Seven saturated liquid densities were obtained in the range of temperature from 244 to 292 K for HFC134a. Eleven saturated liquid densities were obtained in the range of temperature from 285 to 361 K for CFC11. And ten saturated liquid densities were obtained in the range of temperature from 237 to 297 K for CFC12.
The uncertainties of temperature and density are less than ±20 mK and ±3 kg/m³, respectively. On the basis of these results, the saturated liquid density correlations were developed for four halocarbons. The satuated liquid densities for HCFC123 are close to those for CFC11. And the saturated liquid densities for HFC134a are smaller than those for CFC12.
