Abstract
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 (TG) 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.
