| 英文摘要 | this paper reports that the low-temperature heat capacities of pyridine-2,6-dicarboxylicacid were measured by a precision automatic calorimeter over a temperature range from 78 k to 380 k. a polynomial equation of heat capacities as a function of temperature was fitted by the least-squares method. based on the fitted polynomial, the smoothed heat capacities and thermodynamic functions of the compound relative to the standard reference temperature 298.15 k were calculated and tabulated at intervals of 5 k. the constant-volume energy of combustion of the compound was determined by means of a precision rotating-bomb combustion calorimeter. the standard molar enthalpy of combustion of the compound was derived from the constant-volume energy of combustion. the standard molar enthalpy of formation of the compound was calculated from a combination of the datum of the standard molar enthalpy of combustion of the compound with other auxiliary thermodynamic quantities through a hess thermochemical cycle. |
