ABSTRACT
The molar solution enthalpies of ionic liquids (IL) EMIBF4 (1-methyl-3-ethylimidazolium tetrafluoroborate), EMIC (1-methyl-3-ethylimidazolium chloride) and ionic solid NaBF4 at various molalities were determined by the solution-reaction isoperibol calorimeter in water at 298.15 K. In terms of a Debye-Huckel limiting term, the molar solution enthalpies of EMIBF4, EMIC and NaBF4 at infinite dilution, deltasHm , were obtained. Then the values of apparent relative molar enthalpy were calculated. Hydration heat of both cation EMI+ and anion BF4- was discussed. In terms of values of deltasHm, the reaction heat of NaBF4 + EMIC to EMIBF4 + NaCl was estimated.
