The phase equilibrium in an acetonitrile + water + cyclohexene + chloroform system was studied at 101.3 kPa. A prediction regarding the internal structure of the composition tetrahedron (presence/absence of one/two internal singular points) was made using thermodynamic modeling in AspenPlus V.10.0. The existence of two internal quaternary azeotropes (of node type with a minimum boiling point and of saddle type) was confirmed as a result of a full-scale experiment. Thermodynamic-topological analysis of the structure of phase equilibrium diagrams was carried out to confirm the correctness of the diagram construction.
在101.3 kPa下研究了乙腈 + 水 + 环己烯 + 氯仿体系中的相平衡。使用AspenPlus V.10.0中的热力学模型对组成四面体的内部结构（一个/两个内部奇点的存在/不存在）进行了预测。通过全面实验证实了两个内部四元共沸物（具有最低沸点的节点型和鞍型）的存在。进行了相平衡图结构的热力学拓扑分析，以确认图构建的正确性。
