1,1,1,3,3,3-Hexafluoroisopropylmethyl ether (HFE-356 mmz), with its ODP = 0 and low global warming potential, is a promising alternative foam blowing agent, cleaning fluid, and refrigerant. The vapor pressure was measured by static method at temperature range from 323.10 to 448.20 K and corresponding pressure from 97.2 to 2209.7 kPa. These experimental results were fitted to the four parameter Wagner-type equation and compared with literature data. And the compressed liquid density was measured by U-tube vibration method with the temperature range 313.09–448.09 K and pressure range 414–25002 kPa. Based on the experimental data, the saturated liquid density equation and Tait equation were fitted.

“…When compared to the data obtained from REFPROP 9.1, the average absolute relative deviations (AARDs) were 0.32, 0.23, and 0.28% for HFC-134a, HFC-143a, and HFO-1234ze(E), respectively. The vapor pressures in this work combined with the values obtained from the literature ,,− were correlated by a Wagner-type equation. The functional form of the Wagner-type equation is given by The comparison between experimental data and the values calculated by the Wagner-type equation is also shown in Table , and the parameters of the Wagner-type equation are listed in Table .…”

“…trans -1,3,3,3-Tetrafluoropropene (HFO-1234ze(E)) has been considered as a promising alternative to 1,1,1,2-tetrafluoroethane (HFC-134a) in recent years due to its low global warming potential (GWP) and zero ozone depletion potential (ODP). Research on its thermophysical properties has attracted a lot of attention, and equations of state for HFO-1234ze(E) have been established. − However, HFO-1234ze(E) has a lower coefficient of performance (COP) and a lower volumetric refrigeration capacity than HFC-134a, which is mainly caused by the low evaporating pressure and small vaporization enthalpy of HFO-1234ze(E). To offset these drawbacks, mixtures composed of HFO-1234ze(E) with HFCs or HCs have been proposed and some VLE and pvTx properties have been investigated. − 1,1,1-Trifluoroethane (HFC-143a) has higher vapor pressures than HFO-1234ze(E) and was mainly used as a component of R404A (0.44 HFC-125 + 0.04 HFC-134a + 0.52 HFC-143a by mass) and R507A (0.5 HFC-125 + 0.5 HFC-143a by mass). − Moreover, HFC-143a has the potential to be used as a solvent in supercritical extraction because of its low critical temperature and chemical stability, but it was hardly used as a pure refrigerant individually because of its high GWP of 4470 .…”

The critical temperatures and pressures of the binary mixture of 1,1,1-trifluoroethane (HFC-143a) + trans-1,3,3,3-tetrafluoropropene (HFO-1234ze(E)) were measured by a set of apparatus containing an optical cell that has a variable inner volume. The experimental measurements were carried out based on a static method, and the critical properties were determined by means of the observation of disappearance and reappearance of the meniscus. The experimental uncertainties in pressure, temperature, and mole fraction were estimated to be less than 6.2 kPa, 0.02 K, and 0.003, respectively. The experimental critical properties measured in this work were correlated by the Redlich–Kister method, and the correlated results showed a good agreement with experimental data.

“…Considering the density range of the present work is up to 882.0 mol·m –3 , the experiment data were correlated by a three-term virial equation, the form of which is expressed as follows: where the gas constant R = 8.314472J·mol –1 ·K –1 . The second and third virial coefficients were derived from the present measurements and they were fitted to the following temperature relationships: where the T r = T / T c , and the T c is critical temperature of the sample. According to eq and the experimental data in Table , the virial equation of the HFE-356 mmz can be correlated, and the values of the regression coefficients are listed in Table .…”

As one of the most promising alternative refrigerants, 1,1,1,3,3,3-hexafluoro-2-methoxypropane (HFE-356 mmz) is considered to have the potential to be applied in a high temperature heat pump and the organic Rankine cycle. The gaseous pvT properties of HFE-356 mmz were measured using the isochoric method in the temperature range from 333.068 K to 451.226 K, the pressure range from 104.9 to 1997.3 kPa, and the density range from 75.0 mol•m −3 to 882.0 mol•m −3 . The threeterm truncated virial equation of state for gaseous HFE-356 mmz was also fitted based on the experimental data.
