Abstract:   The CPMD simulations were employed to  investigate thermal decomposition of the solid nitromethane. It is found that it  undergoes chemical decomposition at about 2200 K under ambient pressure. The  initiation of reactions involves both proton transfer and commonly known C-N  bond cleavage. 75 species and 100 elementary reactions were observed with the  final products being H2O, CO2, N2 and CNCNC. It represents the first complete  simulation of solid phase explosive reactions reported to date, which is of far  reaching implication for design and development of new energetic  materials.
