Surface Tension Measurements of Propane (R-290) and Isobutane (R-600a) from (253 to 333) K

The surface tensions of propane (R-290) and isobutane (R-600a) were measured over the temperature range (253 to 333) K using a differential capillary rise method (DCRM) under vapor−liquid equilibrium conditions. The temperature and surface tension uncertainties were estimated to be within ±10 mK and ±0.15 mN·m-1, respectively. The present data were used to develop van der Waals-type surface tension correlations for propane (R-290) and isobutane (R-600a). Present results were compared with the available literature data.
