The molar surface Gibbs free energy and its application 2: Ionic liquids 1-alkyl-3-methylimidazolium threonine salts [Cnmim][Thr] (n = 2, 4) at T = (288.15 to 328.15) K

A new Eötvös equation, g = B1(Tc − T), was obtained, where g is the molar surface Gibbs energy; B1 = s is the molar surface entropy; the product of B1 with critical temperature, Tc, is the molar surface enthalpy, h, which is a temperature-independent constant.83
