Abstract |
|
|
|
A novel compound, 1-octylammonium
malate (abbreviated as C8H17NH3C4H5O5
(s)) was synthesized by the method of liquid phase synthesis. Elemental
analysis and X-ray single crystal diffraction techniques were applied to
characterize its composition and structure. Lattice potential energy was
derived from the crystal data of the title compound. According to Pitzer's electrolyte solution
theory, the molar enthalpy of dissolution of C8H17NH3C4H5O5(s) at infinite dilution and Pitzer's parameters were obtained. Then the values of
apparent relative molar enthalpy and relative partial molar enthalpies of
solvent and solute were calculated, respectively.
