Saturated Pressure Measurements of trans-1-Chloro-3,3,3-trifluoroprop-1-ene (R1233zd(E))

Hydrofluoroolefins (HFOs) and hydrochlorofluoroolefins (HCFOs) are two of the most promising families of low-GWP fluids being investigated as alternatives for HFCs in HVAC&R applications. Within the HCFO family, trans-1-chloro-3,3,3-trifluoropropene (R1233zd(E)) is a compound with a relatively high normal boiling point temperature (~291.1 K) and was developed primarily as a blowing agent for polymer foams, a low-pressure refrigerant for chiller applications, and a working fluid for low-temperature ORC applications. This article presents 81 vapor pressure data points measured over the temperature range from (234.15 to 375.15) K in two different laboratories. The data are fitted to Wagner-type and Antoine-type equations and compared to existing correlations and other published data.
