“…Kagawa and Matsuguchi have reported isobaric heat capacities in the gaseous phase in the temperature range from 308 to 363 K at the pressure up to 1 MPa, and determined the ideal gas heat capacities by extrapolating the isothermal data to zero pressure. Transport properties such as viscosity and thermal conductivity have been reported by Mondal et al. , The viscosities were measured by the capillary tube method in the temperature range from 314 to 394 K for the liquid, 391 to 453 K for the vapor, and 413 to 453 K for the supercritical region at the pressure up to 4 MPa. The thermal conductivities were measured by the transient hot-wire method in the temperature range from 313 to 393 K at the pressures up to 4 MPa for the liquid, 313 to 453 K at the pressures up to 2.5 MPa for the vapor, and 413 to 453 K at the pressures up to 4 MPa for the supercritical region.…”

Thermophysical properties such as entropy, heat capacity, and thermal conductivity of trans-1,1,1,4,4,4-hexafluoro-2butene, which is designated as R1336mzz(E) for refrigerant use, were derived from the sound speed measurement in the gaseous phase. The gaseous sound speed was measured by using an acousticmicrowave resonator with a cylindrical cavity, which enables simultaneous measurement of the gaseous relative dielectric permittivity. The ideal gas heat capacity was determined from the gaseous sound speed by analyzing the measurement data with the acoustic-virial equation, and the electric dipole moment was additionally determined from the gaseous relative permittivity measurements. In compliance with the fluid-property correlation models that involve parameters associated with the ideal gas heat capacity and the dipole moment under the corresponding states principle, entropies at saturated vapor and liquid, isobaric heat capacities at saturated liquid, and thermal conductivities at vapor and liquid phases were evaluated for R1336mzz(E).
