Temperature Dependence of Excess Thermodynamic Properties of Binary Mixtures of Organic Compounds

摘要: For calculations on distillation processes it is necessary to know the vapor-liquid-equilibrium (VLE) data at desired temperature range. Very often are available only for different ranges. Therefore convert VLE from one range another.—The excess functions of various types mixtures have very dependence. we classified according dependence Gibbs energy and enthalpy. The thermodynamic properties organic compounds exhibit remarkable regularities.—In case non-associated entropy directly proportional Here simple expressions describing could be obtained The associated can described by Chemical Theory Solutions.—The analysis shows that our classification serves a two-fold purpose. First useful estimating functions. Second how an GE vs. HE(T) curves may enhance general understanding interactions in mixtures.
