摘要: 用改进的双循环型平衡釜测定了4-甲基-2-戊醇和水二元体系的常压汽液平衡(94.37-131.38℃).用封闭管法测定了上述体系在相同温度范围内的液液平衡.以NRTL方程关联液液平衡数据,进而推算常压汽液平衡;与实测结果比较,温度平均偏差为0.61℃,汽相组成平均偏差为0.0131摩尔分数.

Abstract: Vapor-liquid equilibrium of 4-methyl-2-pentanol and water was determined at 760 mm Hg with a modified circulation still within the temperature range of 94.37 to 131.38℃. Liquid-liquid equilibrium for the same system was determined by the closed-tube method in the same temperature range. The NRTL parameters correlated from the liquid-liquid equilibrium data were used to calculate the vapor-liquid equilibrium with mean deviations of temperature and vapor composition of 0.61℃ and 0.0131 mole fraction, respectively.
