根据先前提出的含醇溶液形成的热力学模型，利用充上和释放两个组分间引力 势能的方法，建立了一个含醇溶液超额体积方程．该方程有清晰的物理意义，不仅 能描述各种各样含醇溶液的超额体积随组成的变化规律，而且还能显示自缔合、交 叉缔合和组分间的van der Waals引力对超额体积的贡献．

关键词: 醇, 热力学模型, 缔合, 范德华力

Based on the thermodynamic model of the formation of solutions containing alcohols proposed by our previous work, an equation of excess volume is established by the approach to chai'ging and releasing attractive potential energy between two components. This equation has clear physical significance. It can not only describe the change of excess volume with the composition for various solutions containing alcohols, but also display the contributions of self- association, cross-association, and van der Waals attraction between two components to the excess volume.

Key words: ALCOHOL, THERMODYNAMICAL MODEL, ASSOCIATION, VAN DER WAALS' FORCES
