本文用气相色谱法测定了环丁砜萃取分离芳烃和非芳烃的三元、四元和五元共25个体系的液液平衡数据.用基团贡献模型UNIFAC预测了两相平衡浓度,结果令人满意.
In this paper, the liquid-liquid equilibria data of 25 ternary, quaternary and ternary systems with and without aromatic hydrocarbons extracted by sulfolane were determined by gas chromatography.The equilibrium concentration of two phases was predicted by the group contribution model UNIFAC with satisfactory results .
