Surface properties (surface entropy, surface enthalpy, and surface composition) of dilute solutions of cycloheptanol in ethylene glycol were obtained by using of surface tension measurements at various temperatures. Surface excess values and surface mole fractions were obtained from the Gibbs equation and the extended Langmuir model, respectively. The results show that cycloheptanol is surface-active in ethylene glycol. The lyophobicity of cycloheptanol decreases with increasing temperature.
