ABSTRACT
A new novel amino acid ionic liquid [C4mim][Gly] (1-butyl-3-methylimidazolium glicine) was prepared by the neutralization method. The molar enthalpies of solution, AsolHm(wc), of [C4mim][Gly] with various amounts of water and with various molalities were measured by the solution-reaction isoperibol calorimeter at (298.15 ( 0.01) K. According to Archer s method, the standard molar enthalpies of solution of [C4mim][Gly] with known amounts of water, AsolH0 m(wc), were obtained. To eliminate the effect of the small amount of water in [C4mim][Gly], a linear fitting of AsolH0 m(wc) against water content was carried out so that a good straight line was obtained, and the intercept was the standard molar enthalpy of solution of [C4mim][Gly] without water, AsolH0 m ) (-46.02 ( 0.19) kJ * mol-1. Using Glasser s lattice energy theory, the hydration enthalpy of the glycine anion [Gly]- was estimated.
