本文采用前文（１６）的汽淮平衡器测定仲丁醇－异丁醇，叔丁醇－异丁醇及异丁醇－正丁醇三组二元系统的恒压汽液平衡数据。 实验数据（包括前文侧定的三组醇类－醇类系统和三组醇类水溶液）应用两种缔含溶液模型ＡＳＭＡ和ＡＳＭＢ来关联。同时也与Ｗｉｌｓｏｎ，ＦＨＷ及ＵＮＩＱＵＡＣ方程式的关联结果作了对比，证实：对醇类－醇类系统，ＡＳＭＡ与ＡＳＭＢ模型的拟合精度一般比局部组成方程稍高，对于醇类水溶液．除了水－异戊醇系统外，ＵＮＩＱＵＡＣ的拟合精度最高。
In this paper, the vapor-liquid equilibrium data of three binary systems of sec-butanol-isobutanol, tert-butanol-isobutanol and isobutanol-n-butanol were determined by using the steam / Experimental data (including three alcohol-alcoholic systems and three aqueous alcohol solutions set forth above) should be correlated using two association solution models, ASMA and ASMB. At the same time, it is also compared with Wilson, FHW and UNIQUAC equations. The results show that the fitting accuracy of ASMA and ASMB model is generally higher than that of local compositional equation for alcohol-alcohol systems, and for alcoholic aqueous solution. With the exception of the water-isoamyl alcohol system, UNIQUAC has the highest fitting accuracy.
