本文用热力学方法,为非电解质溶液建立了一个非无热溶液理论,这个理论不包含任何可调参数,完全可由纯组分的性质来预测液体混合物的过量Gibbs自由能.倘若已知混合物的体积,还可预测其过量焓和过量熵.而这些纯组分的性质,都与液体的内压有关.对37个二元系统预测结果表明,实验值的一致性大多优于Scatchard—Hildebrand正规溶液理论及其修正型式SHFH理论.

This paper uses thermodynamics to establish a non-pyrogenic solution theory for non-electrolyte solution. This theory does not contain any adjustable parameters and it is entirely possible to predict the excess Gibbs free energy of the liquid mixture by the properties of the pure constituents. If the volume of the mixture is known , And can also predict the excess enthalpy and excess entropy.The nature of these pure components are related to the internal pressure of the liquid.The prediction results of 37 binary systems show that the experimental values ​​are mostly better than those of Scatchard-Hildebrand normal solution Theory and its modified version of SHFH theory.
