AbstractThe molar enthalpies of dissolution (Delta H-s(m)) of ionic liquids C3MIBF4 (1-methyl-3-propylimidazolium tetrafluoroborate) and C5MIBF4 (1-methyl-3-pentylimidazolium tetrafluoroborate) in water were determined by a solution-reaction isoperibol calorimeter at 298.15 K. According to Pitzer's electrolyte solution theory, the standard molar enthalpy values of solutions of C3MIBF4 and C5MIBF4, Delta H-s(m)circle minus and Pitzer parameters: beta((0)L)(MX) and beta L-(1)(MX), were obtained, respectively. The hydration enthalpies of cations Delta H+ in C5MIBF4 and C3MIBF4 estimated from Glasser's theory of lattice energy were - 171 and -207 kJ circle mol(-1), respectively.
