摘要：
A corresponding-states group-contribution method is proposed to estimate the surface tension of ionic liquids covering wide ranges of temperature (268.29-533.20 K) and surface tension (15.50-76.20 mN/m) based on experimental data collected from literatures. A good agreement between the predicted and experimental data from literature was obtained for total 1224 data points of 105 ionic liquids with an average absolute deviation (AAD) of 4.95%. The corresponding-states group-contribution method developed in this paper offers a simple but reliable approach for estimating surface tension of new ionic liquids in wide ranges of temperature at atmospheric pressure.
