AbstractA colorless and transparent ionic liquid BMIC/ZnCl2 was prepared by mixing 1-butyl 3-methylimidazolium chloride(BMIC) and ZnCl2 with a molar ratio of 1:1 at 363.15 K under stirring in a glove box filled with dry argon. The molar dissolution enthalpies, Delta H-s(m), of BMIC/ZnCl2 in water with various molalities were determined by a solution-reaction isoperibol calorimeter at 298.15 K. In terms of Pitzer electrolyte solution theory, the molar solution enthalpy of BMIC/ZnCl2 at infinite dilution, Delta H-s(m)0, and Pitzer parameters: beta((0)L)(Mx),beta((1)L)(MX) and C-MX(phi L) were obtained, respectively. According to Lecocq's viewpoint, ionic liquid BMIC/ZnCl2 with a molar ratio of 1:1 is a single compound BMIZnCl3. In terms of Glasser's theory and thermodynamic cycle, the standard molar hydration enthalpy of ionic liquid BMIZnCl3, (Delta H-+(0) + Delta H--)(0) = -497 kJ/mol, was calculated. The standard molar enthalpies of hydration of individual ions can be obtained from those of electrolytes, provided that the value of one ion is known. The standard molar enthalpies of hydration of cation BMI+ were estimated Delta H-+(0) (BMI+) = -225 kJ/mol in literature so that the standard molar enthalpies of hydration of ZnCl3- was obtained, that is, Delta H--(0) (ZnCl3-) = -272 kJ/mol.
