摘要(Abstract)：

采用汽液双循环相平衡仪测定了101.33 k Pa下苯-噻吩、苯-二甲基亚砜及苯-噻吩-二甲基亚砜的等压汽液相平衡数据。两组二元体系实验数据均通过了Herington面积法的热力学一致性检验,分别采用NRTL和UNIQUAC活度系数模型对二元体系实验数据进行热力学关联,得到了相应的模型参数,温度偏差和汽相组成偏差,关联结果表明两种模型均能较好的关联实验数据,其中UNIQUAC模型的关联结果稍优于NRTL。利用二元体系UNIQUAC模型参数预测三元体系汽液平衡数据,预测值与实验值相比,平均温度偏差1.37 K,汽相各组分平均绝对偏差均在3%以内,获得了较优的预测结果,从而为工业上苯-噻吩萃取精馏分离过程提供可靠的热力学基础数据。
