摘要	The heats of hydration reactions for MgCl2. 4H(2)O and MgCl2. 2H(2)O include two parts, reaction enthalpy and adsorption heat of aqueous vapor on the surfaces of magnesium chloride hydrates. The hydration heat for the reactions MgCl2. 4H(2)O+2H(2)O --> MgCl2. 6H(2)O and MgCl2. 2H(2)O+2H(2)O --> MgCl2. 4H(2)O, measured by DSC-111, is -30.36 and -133.94 kJ mol(-1), respectively. The adsorption heat of these hydration processes, measured by head-on chromatography method, is -13.06 and -16.11 kJ mol(-1), respectively. The molar enthalpy change for the above two reactions is -16.64 and -118.09 kJ mol(-1), respectively. The comparison between the experimental data and the theoretical values for these hydration processes indicates that the results obtained in this study are quite reliable.
