Vapor Pressure, (p, rho, T) Behavior, Saturated Densities, and Surface Tension of trans-1,2-Dichloroethene [R1130(E)]

The (p, rho, T) behavior of trans-1,2-dichloroethene [R1130(E)] were experimentally investigated based on the isochoric method. A total of 73 single-phase (p, rho, T) data (52 vapor phase and 21 liquid phase) were obtained along 15 isochores at temperatures from 329 K to 453 K and pressures up to 10.5 MPa. A total of 14 vapor pressure data were obtained along an isochore close to the critical density. Several saturated vapor and liquid densities were analytically determined from the intersections of the vapor pressure curve and single-phase isochores. These experimental data are reasonably represented with the extended corresponding states (ECS) model employing the universal parameters generalized to hydrofluoroolefins. Moreover, the measurement of surface tensions was attempted for R1130(E) with the differential capillary rise method, and a total of 38 surface tension data were obtained at temperatures from 228 K to 373 K. They were successfully correlated with different two correlations. Differences between the experimental data and calculated values with the correlations are almost within the uncertainty.
