The existence of two ternary azeotropes in a ternary system was experimentally confirmed for the first time. The boiling point and the composition of azeotropes benzene + water, perfluorobenzene + water, and benzene + perfluorobenzene + water (with a minimum boiling temperature) as well as the boiling point of the ternary azeotrope of the saddle type were measured at 101 kPa using distillation analysis, ebulliometric titration, and gas chromatography. The parameters of the NRTL-RK model were selected from the AspenPlus V.10.0 database, allowing an adequate description of the phase equilibrium in the system studied. Possible evolution of the VLE diagram under pressure change was discussed.

苯+全氟苯+水系统中101 kPa的双三元共沸物

首次通过实验确定了三元体系中两个三元共沸物的存在。用蒸馏法测定101kPa下的共沸物苯+水，全氟苯+水，苯+全氟苯+水的沸点和组成（沸点最低）以及马鞍型三元共沸物的沸点。分析，浊度滴定和气相色谱。NRTL-RK模型的参数选自AspenPlus V.10.0数据库，可以充分描述所研究系统中的相平衡。讨论了在压力变化下VLE图的可能演变。
