عنوان انگلیسی Metal-Containing Ionic Liquids: Anion and Cation Contribution on Thermo-Physical Parameters
چکیده انگلیسی مقاله Continuing the success of the researchers on ionic liquids application in biomedicine, lithium-sodium batteries, and chemical engineering, we try to investigate temperature, cation, and anion contribution in the most important thermodynamic parameters of the 33 metal containing ionic liquids. Critical parameters, density, thermal expansion coefficient, critical compressibility factor, surface tension, and lattice energy of studied systems carried out based on classical thermodynamic methods and compared by reported experimental data in the literature. Results revealed that 1-hexyl-3-methyl-imidazolium and tungsten hepta fluoride as anion show the higher contribution in Tb (boiling temperature), while hepta-chlorodialuminate and 1-hexyl-3-methyl-imidazolium as cation showed the main contribution in Vc (critical volume) respectively. Temperature dependence of density has been perfectly determined by the first-order polynomial and our proposed method in the present work. 3D graph of surface tension as a function of cation, and anion structure determined the anion group are found the important influence in surface tension at constant temperature due to the greater polarizability, the lower hydration, and consequently screening the electrostatic repulsion between IL head groups. Undoubtedly, the information provided in this research is an important help to scientists to choose the appropriate ionic liquid in specific conditions.
