| 摘 要： | 采用新型的双循环沸点仪测定了在101.3 kPa下四氢呋喃-水-乙二醇和四氢呋喃-水-1,4-丁二醇体系的等压气液平衡数据.讨论了不同萃取剂对四氢呋喃的相对挥发度的影响.实验结果表明,乙二醇和1,4-丁二醇都能消除四氢呋喃-水体系的共沸点,并使四氢呋喃对水的相对挥发度明显提高,可作为萃取分离四氢呋喃-水的萃取剂.

| Abstract: | Isobaric Vapor-Liquid Equilibrium data for tetrahydrofuran–Water–ethanediol and tetrahydrofuran–water-1,4-butanediol system at 101.33kPa were measured by a new type of two-cycle ebulliometer.The effect of different extractant on relative volatility of tetrahydrofuran was discussed.The experimental results show that ethanediol and 1,4-butanediol eliminated the azeotropic point of tetrahydrofuran–water system and significantly raised the relative volatility of tetrahydrofuran–water.Ethanediol and 1,4-butanediol were suitable for extraction distillation of tetrahydrofuran-water. |
