SURFACE TENSION OF POLAR LIQUIDS AND MIXTURES

The simple principle of corresponding states for surface tension, has been generalized to include polar compounds (including those exhibiting hydrogen bond) and their mixtures, by introducing an additional parameter to characterize molecular polarity. In addition the statistical tool of factor analysis has been used to correlate this parameter. For mixtures a binary interaction parameter is also needed, which has also been correlated with easily available properties. Good agreement has been obtained for a wide range of pure liquids and mixtures.
