抄録

By a differential capillary rise method, the surface tension was measured for a new candidate of low GWP refrigerant HFO-1123. 16 points of surface tension data with a propagated uncertainty of approximately ±0.22 mN m^-1 are presented in this paper. Based on the measured data, a Van der Waals type empirical correlation was proposed for HFO-1123:  = 61.02 (1-T/Tcrit)^1.30 [mN m^-1], where Tcrit is a critical temperature of 331.7 K measured by Higashi and Akasaka. This empirical correlation agrees with the measured surface tension data at temperatures from 267 K to 304 K.
