英文摘要: The low-temperature heat capacity C (p,m) of erythritol (C(4)H(10)O(4), CAS 149-32-6) was precisely measured in the temperature range from 80 to 410 K by means of a small sample automated adiabatic calorimeter. A solid-liquid phase transition was found at T=390.254 K from the experimental C (p)-T curve. The molar enthalpy and entropy of this transition were determined to be 37.92 +/- 0.19 kJ mol(-1) and 97.17 +/- 0.49 J K(-1) mol(-1), respectively. The thermodynamic functions [H (T)-H (298.15)] and [S (T)-S (298.15)], were derived from the heat capacity data in the temperature range of 80 to 410 K with an interval of 5 K. The standard molar enthalpy of combustion and the standard molar enthalpy of formation of the compound have been determined: Delta(c) H (m) (0) (C(4)H(10)O(4), cr)= -2102.90 +/- 1.56 kJ mol(-1) and Delta(f) H (m) (0) (C(4)H(10)O(4), cr)= - 900.29 +/- 0.84 kJ mol(-1), by means of a precision oxygen-bomb combustion calorimeter at T=298.15 K. DSC and TG measurements were performed to study the thermostability of the compound. The results were in agreement with those obtained from heat capacity measurements.
