ABSTRACT
The compound 1-decylammonium hydrochloride was synthesized by the method of liquid phase reflux. Chemical analysis, elemental analysis, and X-ray crystallography were applied to characterise its composition and structure. The lattice potential energy of the crystalline solid compound was calculated from data of the crystal structure. The values of the molar enthalpy of dissolution of 1-decylammonium hydrochloride at different concentrations (m) at T = 298.15 K were measured by means of an isoperibol solution reaction calorimeter. According to the Pitzer electrolyte solution theory, the molar solution enthalpy of C10H21NH3Cl(s) at infinite dilution (DsH1m ) and Pitzer parameters obo0PL MX and bo1PL MX ) were obtained. Then the apparent relative molar enthalpy (UL) of the title compound and relative partial molar enthalpies of solvent and solute (L1 and L2) were calculated, respectively. Hydration heats of the solid compound and its cation were derived from the molar solution enthalpy of the title compound at infinite dilution (DsH1m ) and the lattice potential energy.
