摘要(Abstract)：

用改进的Rose釜测定了101.3 kPa下异丙醇-异丁醇、异丙醇-正丁醇、异丁醇-正丁醇3个二元体系及异丙醇-异丁醇-正丁醇1个三元体系的汽液平衡数据。3组两元汽液平衡数据均通过了Herington热力学一致性检验,三元汽液平衡数据也通过了McDermett-Ellis热力学一致性检验。分别用Wilson、NRTL和UNIQUAC方程对二元汽液平衡数据进行了关联,得到了相应的模型参数及关联偏差。对于3个二元体系而言,Wilson和UNIQUAC模型方程比NRTL模型方程的关联效果好。最后运用关联得到的Wilson二元交互作用参数预测了三元体系的汽液平衡数据,平衡温度的平均绝对偏差为0.52℃,异丙醇的汽相摩尔组成平均绝对偏差为0.0057,异丁醇的汽相摩尔组成平均绝对偏差为0.0048,实验值与预测值基本吻合。
