摘要
用鼓泡平衡釜测定了乙醇-水系统在常压下的汽液平衡数据,用Wilson方程关联实验数据,实验数据计算值和测定值能较好的符合并得到了乙醇—水的模型参数,汽相组成平均偏差为-0.146(摩尔分数)。此外,还讨论了加入萃取剂对乙醇-水系统汽液平衡的影响。
The VLE data of ethanol-water system were measured by using a bubble-equilibrium, still The data were correlated by Wilson equation. The results showed that the calculated values were well Consistent With experimental data and the parameters of binary system ethanol-water were acquired .The mean deviation of vapor compositions was -0.146（mol）. Furthermore, the influence of solvent with extraction of ethanol-water VLE systems was discussed.
