摘要: The molar heat capacity Cp,m of 1-cyclohexene-1,2-dicarboxylic anhydride was measured in the temperature range from T = 80 K to T = 360 K with a small sample automated adiabatic calorimeter. The melting point Tm, the molar enthalpy △fusHm and the entropy△fusSm of fusion for the compound were determined to be (343.46±0.24) K, (11.88±0.02) kJ×mol-1 and (34.60±0.06) J×K-1×mol-1, respectively. The thermodynamic functions [H(T)-H(298.15)]and [S(T)-S(298.15)] were derived in the temperature range from T = 80 K to T = 360 K with temperature interval of 5 K. The Purity of the sample used in the adiabatic calorimetric study was determined to be 99.28% by using the fractional melting technique. The thermal stability of the compound was investigated by Differential Scanning Calorimeter (DSC) and Thermogravimetric (TG) technique, and the process of the mass-loss of the sample was due to the evaporation, instead of its thermal decomposition.
