本文概述了缔合溶液理论的发展和研究状况,并利用双参数模型、MK 模型、KW 模型,借助 VLE 数据,对几种醇一惰性烃和醇—活性烃体系,确定了醇的自缔合平衡常数以及醇和活性烃问的交叉缔合平衡常数.结果表明K—W模型给出的 G~E 平均相对误差最小,其次为 MK 模型,双参数模型关联结果最差.由 KW和 MK 型,得出醇在惰性溶剂中的自缔合平衡常数不随溶剂变化,反映了醇自身的性质;在活性溶剂中的自缔合平衡常数与溶剂有关. In this paper, the development and research status of the theory of association solution are summarized. By using the two-parameter model, the MK model, the KW model and the VLE data, several alcohol-inert and alcohol- Equilibrium constants and cross-association equilibrium constants between alcohols and active hydrocarbons were obtained.The results showed that the average relative error of G to E given by K-W model was the smallest, followed by MK model, The self-association equilibrium constant of alcohol in inert solvent does not change with the solvent, which reflects the properties of alcohol itself. The self-association equilibrium constant in the active solvent is related to the solvent.
