英文摘要: Low-temperature heat capacities of the Compound Ni(C4H7O5)(2)center dot 2H(2)O(s) have been measured with an automated adiabatic calorimeter. A thermal decomposition or dehydration occurred in 350-369 K. The temperature, the enthalpy and entropy of the dehydration were determined to be (368.141 +/- 0.095) K, (18.809 +/- 0.088) kJ(.)mol(-1) and (51.093 +/- 0.239) J(.)K(-1.)mol(-1) respertively. The experimental values of the molar heat capacities in the temperature regions of 78-350 and 368-390 K were fitted to two polynomial equations of heat capacities (C-p,C-m) with the reduced temperatures (X), [X=f (T)], by a least squares method, respectively. The smoothed molar heat capacities and thermodynamic functions of the compound were calculated on the basis of the fitted polynomials. The smoothed values of the molar heat capacities and fundamental thermodynamic functions of the sample relative to the standard reference temperature 298.15 K were tabulated with an interval of 5 K.
