1. Decomposition Kinetics of 1,1-Diamino-2,2-dinitroethylene (Fox-7). 2. Reaction in the Solid State

The kinetics of the thermal decomposition of 1,1-diamino-2,2-dinitroethylene (FOX-7) in the solid state is investigated by the manometric and calorimetric methods. The conditions are found under which the solid-phase reaction and the accompanying fast side processes of substance sublimation and vapor decomposition are separated in time, and the contribution of secondary reactions to the initial rate of solid-phase decomposition is small. The rate constant of the noncatalytic stage of decomposition of the substance in the solid phase is determined under these conditions.
