报告摘要:
Ab initio transition state theory based master equation calculation for the thermal decomposition kinetics of MMH will be presented in the talk. The simple NN and CN bond fission to produce the radicals CH3NH + NH2 and CH3 + NHNH2 dominates the decomposition kinetics. The transition state theory calculation directly provides high pressure dissociation and recombination rate coefficients for these reactions. Predictions of the pressure dependence and product branching in the dissociation of MMH are obtained by solving the master equation for a wide range of temperatures and pressures relevant to rocket operations. A study on the secondary channels in the thermal decomposition kinetics of MMH will be discussed for their potential importance in modeling product formation from the MMH decomposition.
