For the surface tension of otganic compounds, (+ = [ 6 -( p , -p,)I4 is proposed where 6 = 6,.(1-T,)0.37.T,.exp(0.30066/T, + 0.86442.T:). p! and pu are molar densities of liquid and vapor, respective&, T, = T/T,, and CP, is a temperature-independent, compound-dependent constant similar to Sugden ' s

The surface tensions of the n-propanol/ethylene glycol/water ternary mixture and its binary mixtures are measured at 293 K and described by mathematical functions. The experimental data and their descriptions are shown in the three-dimensional space by means of coordinate transformation. A thermodyn
The composition dependence of the surface tension of highly nonideal organic-organic and aqueous-organic nonelectrolyte solutions is described, based on the assumption that the surface layer can be treated as a separate phase located between vapor and bulk liquid phases. The Wilson, NRTL, and UNIFAC
