Abstract

This study presents experimental measurements of the vapor pressures and pressure-volume-temperature (PVT) properties of trans-1,1,1,3-tetrafluoro-2-butene, also known as HFO-1354mzy(E). This substance is expected to be a candidate working fluid for high-temperature heat pumps. The densities were measured by magnetic levitation densimeter (MLD). Vapor pressures were measured over the temperature range from (340 to 410) K, at pressures from (0.5 to 2.5) MPa. Liquid-phase PVT properties were measured at temperatures between (280 and 420) K at pressures up to 20 MPa. Gas-phase PVT properties were measured in the temperature range from (340 to 420) K at pressures from (0.5 to 2.5) MPa. The experimental uncertainties of the present measurements were estimated to be within ±18 mK in temperature, ±2.9 kPa in pressure, and ±0.012 % in density, respectively. The vapor pressure correlation and equations of state (EoS) for the liquid-phase and gas-phase PVT properties were derived. The vapor pressure correlation and the proposed EoS were found to well represent the set of measurements within a deviation of ±0.13 % in vapor pressure, ±0.2 % in liquid phase density, and ±0.3 % in pressure for the gas-phase PVT properties, respectively.
