简介:二进制蒸汽液体平衡(VLE)数据为2-propanol/ethanediol和ethanediol/potassium醋酸盐(KAc)的系统被测量。为propanol/ethanediol的系统的VLE数据用热力学的一致性测试被测试。y1和P的平均价值分别地是0.0776和0.1542kPa。VLE数据的上述二个集合与NRTL模型一起被相关。为2-propanol/water/KAc的系统的第三的VLE数据被用来为2-propanol/KAc和water/KAC(叫的TDCM)的二进制系统获得NRTL模型的更合适的参数。为multicomponent系统,第三、第四级,NRTL模型预言的VLE价值与文学数据同意了很好。KAc的KAc,ethanediol和在2propanol和水之间的轻快上的ethanediol的影响分别地被调查。结果证明上述材料和混合物在在2-propanol和水之间的轻快上有不同影响。为咸包含的VLE的关联和预言的方法为说的系统简单、有效。
