| Abstract: | The pyrolysis of di-tert-butyl sulfide has been investigated in static and stirred-flow systems at subambient pressures. The rate of consumption of the sulfide was measured in some experiments, and the rate of pressure increase was followed in others. The results suggest that the reaction is essentially homogeneous in a seasoned reactor and proceeds through a free radical mechanism. In the initial stages, the decomposition rate follows first-order kinetics, and the rate coefficient in the absence of an inhibitor is given by  between 360 and 413°C. The stoichiometry of the uninhibited reaction at 380°C and 50% decomposition is approximately  between 360 and 413°C. The stoichiometry of the uninhibited reaction at 380°C and 50% decomposition is approximately. |
