英文摘要: The molar heat capacity C-p,C-m of 1,2-cyclohexane dicarboxylic anhydride was measured in the temperature range from T=80 to 390 K with a small sample automated adiabatic calorimeter. The melting point T-m, the molar enthalpy Delta H-fus(m) and the entropy Delta S-fus(m) of fusion for the compound were determined to be 303.80 K, 14.71 kJ mol(-1) and 48.43 J K-1 mol(-1), respectively. The thermodynamic functions [H-T-H-273.15] and [S-T-S-273.15] were derived in the temperature range from T=80 to 3 85 K with temperature interval of 5 K. The thermal stability of the compound was investigated by differential scanning calorimeter (DSC) and thermogravimetry (TG), when the process of the mass-loss was due to the evaporation, instead of its thermal decomposition.
