Measurements of the surface tension of glycerol, ethylene glycol, formamide, [alpha]-bromonaphthalene, and benzene, as well as of the interfacial tension of polar liquid-apolar liquid, were made. On the basis of the surface tension of n-alkane and the interfacial tension of n-alkane-polar liquid the dispersion and nondispersion or Lifshitz-van der Waals and acid-base components of glycerol, formamide, and ethylene glycol were calculated and compared with those obtained in different ways. Then the values of electron-acceptor and electron-donor parts of acid-base components of glycerol, ethylene glycol, and formamide were calculated and compared with those obtained from contact angle measurements. The Lifshitz-van der Waals and the electron-acceptor and electron-donor components of the liquids mentioned above were also calculated solving a system of equations obtained on the basis of the measurements of their surface tension and interfacial tensions for polar liquid-diiodomethane and polar liquid-benzene systems. On the basis of the measurements and calculations the authors found that the values of the dispersion and nondispersion components of glycerol, ethylene glycol, and formamide differ depending on the kind of n-alkane. It was found that using the dispersion and nondispersion components of the surface tension of the liquids studied for calculation of the interfacial tension for some liquid-liquid systems gave almost the same results as using Lifshitz-van der Waals and acid-base ones. On the basis of measurements and calculations it is stated that the specific orientation of molecules at the liquid-liquid interface and the mutual solubility of phases that are in contact influence the values of components of liquid surface tension calculated from liquid-liquid interface tension measurements.
