The paper presents the properties of mixtures of benzyl alcohol and ethylene glycol at the liquid/air interface. The properties were studied by surface tension measurements carried out at as a function of the mole fraction of benzyl alcohol at temperatures between (20 and 50) C. It was shown that at constant temperature by the addition of benzyl alcohol the surface tension decreases and at constant composition by the increasing of temperature the surface tension decreases linearly. The surface entropies and enthalpies were calculated from experimental data. The surface composition of the mixture at a low concentration of benzyl alcohol was obtained from the extended Langmuir model. Values of the excess surface tension for mixtures were calculated and show a negative deviation from ideality.
