【摘要】 用鼓泡平衡釜测定了环己烷 乙醇 异丁醇体系在35℃、45℃、60℃、75℃时的等温汽液平衡,用NRTL方程关联实验数据,计算值与测定值符合较好,气相组成平均偏差为0 0069(摩尔分数)。此外,还考察了环己烷浓度对乙醇和异丁醇间相对挥发度的影响。更多还原

【Abstract】 The vapour liquid equilibrium data of ternary system cyclohexaneethanolisobutanol at 35℃,45℃,60℃ and 75℃ were experimentally measured with a bubbleequilibrium still. The data were correlated by NRTL equation. The results showed that the calculated values are well consistent with experimental data. The mean deviation of vapor compositions is 0006 9.更多还原
