英文摘要: Heat capacities of benzyl disulfide have been measured with a high-precision automatic adiabatic calorimeter over the temperature range from 80 to 377 K. The melting point, molar enthalpy and entropy of fusion were determined to be 341.72 +/- 0.07 K, 44965 10 J mol(-1) and 130.78 +/- 0.11 J K-1 mol(-1), respectively. The thermal stability and the kinetics of thermal decomposition of the compound were investigated in air by means of thermogravimetry JG) and differential thermal analysis (DTA). TG/DTA curves showed that the decomposition proceeded through one step. The activation energy and the reaction order for one-step decomposition was calculated to be 110.7 +/- 12.3 kJ mol(-1) and 1.2 +/- 0.2 through Kissinger method. (C) 2007 Elsevier B.V.
