摘　　要：用自制的液液平衡器测定了 2 98.15K下异丙醇 -苯 -水 -氟化钾体系的液液平衡数据。考察了氟化钾对该体系的分配系数和选择性系数的影响。对所测数据用改进的Eisen -Joffe方程进行了关联 。Liquid-liquid equilibrium data for the system of isopropanol-benzene-water in the presence of potassium fluoride at 298.15 K were measured using the self-made liquid liquid equilibrium apparatus made by authors. The experimental data of the LLE have been correlated using the modified Eisen-Joffe equation. The results of the correlation were good. The effect of potassium fluoride on the distribution efficiency and the selectivity was investigated too.
