| Abstract: | The combustion energy of thioproline was determined by the precision rotating-bomb calorimeter at 298.15 K to be Δc U= –2469.30±1.44 kJ mol–1. From the results and other auxiliary quantities, the standard molar enthalpy of combustion and the standard molar enthalpy of formation of thioproline were calculated to be Δc H m θC4H7NO2S, (s), 298.15 K= –2469.92±1.44 kJ mol–1 and Δf H m θC4H7NO2S, (s), 298.15K= –401.33±1.54 kJ mol–1. |
