Ionic liquids (ILs) with their limitless combination of cations and anions can offer an optimal solvent for a specific purpose especially separation processes. Among ionic liquids, alkyl-sulfate derivatives are the most promising ILs to be applied in industrial processes. The present work investigates liquid-liquid equilibrium phase behavior of 12-ILs comprising sulfate-based anions. Computation of liquid-liquid equilibrium for 36 ternary systems is carried out using three local composition models, namely non-random two liquid (NRTL), non-random two liquid non-random factor (NRTL-NRF) and universal quasi chem. (UNIQUAC) activity coefficient models. All the interaction parameters of the three models are regressed using an optimization program based on Simplex method of Nelder and Mead. Comparison of the results is expressed by root mean square deviation (rmsd) between the exptl. and calculated compositions It is demonstrated that the NRTL-NRF model presents very good satisfactory results with rmsd values of about 1.05 so that this model is highly appropriate to calculate thermodn. properties of ionic liquid solutions This study involved multiple reactions and reactants, such as 1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate (cas: 478935-29-4HPLC of Formula: 478935-29-4).
1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate (cas: 478935-29-4) belongs to imidazole derivatives. Imidazole is the basic core of some natural products such as histidine, purine, histamine and DNA based structures, etc. Among the different heterocyclic compounds, imidazole is better known due to its broad range of chemical and biological properties. Imidazole also acts as a microtubule destabilizing agents and inhibits topoisomerase and Cytochrome P450 Family 26 Subfamily A Member 1 (CYP26A1) enzymes.HPLC of Formula: 478935-29-4
