摘要
测定了2-丁酮-甲苯-水体系在303.15和323.15K、2一丁酮一4一甲基一2一戊酮一水体系在293.15、303.15和313.15K,2-丁酮-环己酮-水体系在293.15和313.15K下的LLE数据.实验数据用NRTL方程关联,部分互溶对和互溶对的方程参数分别从二元和三元LLE数据得到,关联结果与实验数据符合良好.
In this work, the liquid - liquid equilibria (LLE) data of ternary mixtures 2-butanone -toluene -water at 303. 15 and 323. 15K, 2-butanone -4-methyl -2-pentanone -water at 293. 15, 303. 15 and 313. 15K, 2-butanone - cyclohexanone -water at 293. 15 and 313. 15K were measured experimentally. NRTL equation was used to correlate the experimental data. The equation parameters for the partially miscible pairs and the miscible pairs were obtained from binary and ternary LLE data respectively. The evaluation results all a-greed well with the experimental data.
