【摘要】 本文以适用于部分互溶液体的循环式平衡釜,测定760mmHg柱下的正丁醇-异丁醇-水体系的汽液平衡数据。以浊点法测定沸点下该物系的液-液互溶度。 所测三元汽-液相平衡数据及互溶度数据可以Mitsuyasu提出的,修正的三参数Wilson方程进行良好的关联,并用NRTL（Non-Random Two-Liquids）及UNIQUAC（Universal Quasi-Chemi-cal）方程对所测汽-液平衡数据进行了关联。更多还原

【Abstract】 A recirculating still specially designed for partially miscible systems was used for the determination of isobaric vapor-liquid equilibrium data at 760 mm Hg for the n-butanol-isobutanol-water system. For the determination of solubility at the boiling point the cloud point titration method was used.The vapor-liquid phase equilibrium data and solubility data at boiling point for the ternary system under study have been well correlated by the modified Wilson equation proposed by Mitsuyasu. The NRTL and the Uniquac equations were also used for the correlation of the vapor-liquid phase equilibrium data. All the above correlations are adequate for design purposes.更多还原
