Effect of propionitrile nitramine salts on the thermal decomposition of HMX

The thermal decomposition of HMX with additives of metal salts of propionitrile nitramine is studied. The process goes with acceleration by a complex mechanism, in which the interaction of HMX with propionitrile imine and its oligomer formed in the reaction plays an important role. The initial rate of HMX decomposition correlates with the mass fraction of the anion in the salt.
