ABSTRACT
Surface tensions of binary mixtures of ethanol, 1-butanol, or 2-butanol with hexane have been measured in the temperature range 283.15 K to 313.15 K with a drop volume tensiometer. The corresponding surface tension deviations have been calculated and correlated. Using the temperature dependence of surface tensions, the entropy change and enthalpy change of surface formation per unit area were evaluated at 298.15 K.
