英文摘要	low-temperature heat capacity c-p.m of 2,6-dicarboxypyridine (c7h5no4; cas 499-83-2) was precisely measured in the temperature range from (80 to 378) k with a high precision automated adiabatic calorimeter. no phase transition or thermal anomaly was observed in this range. the thermodynamic functions [h-t - h-298.15] and [s-t - s-298.15] were calculated in the range from (80 to 378) k. the standard molar enthalpy of combustion and the standard molar enthalpy of formation of the compound have been determined, delta h-c(m)o (c7h5no4, cr) = -(2741.41 +/- 0.49) kj (.) mol(-1) and delta h-f(m)o(c7h5no4, cr) = -(727.74 +/- 1.50) kj (.) mol(-1), by means of a precision oxygen-bomb combustion calorimeter at t = 298.15 k. the thermodynamic properties of the compound were further investigated through differential scanning calorimeter (dsc) and the thermogravimetric (tg) analysis.
