摘要

•R1132(E) is a promising next-generation refrigerant with zero ODP and very low GWP.•R1132(E) saturation pressures were measured between 240 K to the critical temperature.•The critical pressure of R1132(E) was directly measured as 5172.5 ± 1.0 kPa.•A Wagner-type equation was optimized for the measured saturation pressures.•The acentric factor for R1132(E) was determined and used in the Peng-Robinson EoS.
