摘要: Abstract A new approach for calculating the excess molar enthalpies of binary liquid mixtures at entire pressure range interest based on experimental enthalpy ( H m E ) data low pressure, is proposed. The method a simple thermodynamic relation combined with modified Redlich-Kister equation and local composition model (NRTL Wilson) in which parameters were temperature dependent that are determined by using volume V different temperatures pressures. calculation has been carried out seven systems include light hydrocarbon-alcohol plus water-ethanol. comparison calculated pressures indicate models describe very well quantitatively.
