摘要：提出了一个醇与烃混合的热力学模型 ,据此 ,得到了一个简单的超额焓方程 ,它由物理和化学贡献两部分组成 .这个方程具有一定的通用性 ,能够推广到其它含醇溶液 .方程不仅能满意地用来描述超额焓与组成间的关系 ,而且还能显示组分间的相互作用 .
A thermodynamic model for mixing alcohols and hydrocarbons has been proposed. From this model, a simple equation of excess enthalpy which is composed of the physical and chemical contributions is obtained. The equation has good generality and can be extended to other solutions containing alcohols. It can be satisfactorily used not only to describe the relationship between the excess enthalpy and the composition, but to display the interaction between the components.
