Surface tensions of binary mixtures of ethylene glycol and a homologous series of aliphatic alcohols (1-pentanol, 1-hexanol, and 1-heptanol) were measured as a function of composition using the ring detachment method in the temperature range between (298.15 and 318.15) K. Temperature influence on the behavior of surface tensions and surface properties of binary mixtures has often been used to obtain information about solute structural effects on ethylene glycol. Values of surface tension were correlated with temperature and mole fraction. The experimental data have been used to calculate the surface tension deviation, delta sigma, as a function of mole fraction, and values obtained are fitted to the Redlich-Kister polynomial equation to obtain the coefficients and the standard errors. The maximum deviation was in both cases always less than 0.5%. The temperature dependence of a at fixed composition of solutions was used to estimate surface enthalpy, H-s, and surface entropy, S-s.
