Yang, Lixia; Han, Yuexia; Jiao, Zhen published an article in 2021. The article was titled 《Measurement and Correlation of Liquid-Liquid Equilibria of Water (1) + 1-Methylimidazole (2) + [Bmim][PF6] (3) Ternary Systems between 303.15 and 323.15 K》, and you may find the article in Journal of Chemical & Engineering Data.Computed Properties of C4H6N2 The information in the text is summarized as follows:
To obtain the basic data for the recovery of 1-methylimidazole from wastewater by extraction, the ternary liquid-liquid phase equilibrium data of the water (1) + 1-methylimidazole (2) + 1-butyl-3-methylimidazolium hexafluorophosphate ([Bmim][PF6]) (3) system were determined using an equilibrium autoclave at the temperatures of 303.15 to 323.15 K and 101.32 kPa. The solute distribution coefficient (D) and the selectivity (S) of the ternary system were calculated in accordance with the exptl. data. Their values were up to 1.39 and 41.17, resp., which showed that the ionic liquid can extract 1-methylimidazole effectively. The exptl. results showed that the temperature had a slight effect on the liquid-liquid equilibrium behavior. Meanwhile, the calculated results revealed that the selectivity coefficient decreased with the enhancing concentration of 1-methylimidazole in the ternary system and the increasing temperature In addition, the nonrandom two liquid (NRTL) model was used for correlation of the ternary systems. The root-mean-square deviation value of 0.0218 indicated that the calculated results using the model were in good agreement with the exptl. data and were reliable to apply to practice. The experimental part of the paper was very detailed, including the reaction process of 1-Methyl-1H-imidazole(cas: 616-47-7Computed Properties of C4H6N2)
1-Methyl-1H-imidazole(cas: 616-47-7) is used as a precursor for the synthesis of pyrrole-imidazole polyamides, ionic liquids such as 1-butyl-3-methylimidazolium hexafluorophosphate.Computed Properties of C4H6N2
