英文摘要: The heat capacities of p-dimethylaminobenzaldehyde [p-DMABD] were measured between 80 and 360 K with a small sample automated adiabatic calorimeter. The thermodynamic parameters of solid-liquid phase transition were also obtained. The melting point, enthalpy and entropy of fusion of this compound were determined to be 346.15 K, 19.07 kJ mol(-1) and 55.08 J mol(-1) K-1 respectively. The experiment of purity determination with the adiabatic calorimeter indicated that the sample purity was 99.74% (molar fraction). (C) 1999 Elsevier Science B.V. All rights reserved.
