| Abstract Scope |
The chloroaluminate species distribution of EMIC-AlCl3 system was modeled using thermodynamic data in the temperatures range from 90 to 110oC and 0 to 1.0 mole fraction of AlCl3. Thermodynamic model was developed considering activity (ai) of species and equilibrium constant (k) for the polymeric reactions. The model species distribution results were compared with the available literature data. The main anion species exist from 0 to 0.5 mole fraction of AlCl3 are Cl- and AlCl4- , and Al2Cl7-, Al3Cl10- and Al4Cl13- species exist at higher concentrations of AlCl3. At all temperatures, the distribution peak maxima of AlCl4-, Al2Cl7-, Al3Cl10- and Al4Cl13- occurs at 0.5, 0.67, 0.75 and 0.8 mole fraction of AlCl3 respectively. With increase in temperature, the mole fraction of Al2Cl7-, Al3Cl10-, and Al4Cl13- peak maxima decreases. These species distribution data were used in analyzing the change in physical properties of ionic melts such as electrical conductivity. |
