Enthalpy of Dilution of Aqueous [C4mim][Gly] at 298.15 K

摘要: A novel amino acid ionic liquid [C4mim][Gly] (1-butyl-3-methylimidazolium glycine) was prepared by a neutralization method. The molar enthalpies of dilution, ΔDHm(mi→mf), aqueous at various molalities were measured (298.15 ± 0.01) K. values the apparent relative enthalpy, φL, calculated using both extended Debye−Huckel equation and Pitzer equation, which in good agreement within experimental error. In terms solution [C4mim][Gly], ΔsHm, estimated. estimated ΔsHm consistent with previously obtained.
