摘要
本文报导了101.3 kPa下HCL+H_2O+CH_3aOH体系汽液平衡的实测结果。在对H_2O+CH_3OH混合溶剂中HCI的电离情况进行研讨,并求得HCl在该混合溶剂中亨利常数的基础上,从二元体系的性质出发,用笔者扩展的Pitzer(1980年)模型预测了HCl+H_2O+CH_3OH体系的汽液平衡,得到与实测数据极为一致的结果。
The vapor-liquid equilibrium (VLE) data for ternary mixture of HCl+H_2O+CH_3OH were measured precisely at 101.3 kPa. The partial dissociation of HCl in the mixed solvent H_2O+CH_3OH, the VLE of the ternary system were predicted by the authors' extended Pitzer (1980) model, in which a new method to calculated the Herry's constant of a strong volatile electrolyte such as HCl in mixed solvent was developed, It was demonstrated that from binary data alone the model was capable of representing the VLE of HCl+H_2O+CH_3OH by comparing calculated data with the experimental results.
