离子液体 (氯化1-丙烯基-3-甲基咪唑) -盐双水相体系在不同温度下的液液相平衡行为研究
Phase behavior of aqueous two-phase systems composed by 1-Allyl-3-methylimidazolium chloride and salts aqueous at various temperatures
本文分别测定了氯化1-丙烯基-3-甲基咪唑（[AMIM]Cl）和钾盐（K3C6H5O7、K2C4H4O6）组成的双水相系统在温度T= (288.15, 298.15, 308.15和 318.15) K时的液液相平衡数据。利用Merchuk方程和其他两个方程很好的拟合了其双节线数据。通过杠杆规则计算了双水相的系线数据，并利用Othmer-Tobias 和 Bancroft 方程证明了该数据的精确性，一个两参数方程成功拟合了系线数据。研究了盐的盐析能力为K3C6H5O7 > K2C4H4O6，讨论了温度对双节线相图和系线的影响，得到随着温度的降低，双水相体系的两相区增大。
he liquid-liquid equilibrium data were determined for 1-Allyl-3-methylimidazolium chloride ([Amim]Cl) and potassium salts (K3C6H5O7 or K2C4H4O6) aqueous two phase systems at T= (288.15, 298.15, 308.15 and 318.15) K. The binodal curves data for the experimental data were correlated using the Merchuk equation and two other equations, indicating good agreement was obtained. The tie-line data were calculated by the lever rule and the accuracy was successfully proved using the Othmer-Tobias equation and the Bancroft equation. And a two-parameter equation was successfully used for correlation the tie-line data. The salting-out ability of a series of salts has been studied, as an order of K3C6H5O7 > K2C4H4O6. The temperature dependence on the phase diagram and the tie-lines has also been discussed. The two-phase area was expanded with a decrease in temperature for the investigative ATPSs.
