## Abstract

The mechanism of the thermal decomposition of hydrazinium diperchlorate (HP-2) has been investigated in the temperature range $100-200^oC$. The decomposition can be represented by the chemical equations: $Below 140^oC N_2H_6(ClO_4)_2 \rightarrow N_2H_5ClO_4 +HClO_4$ $Above 140^oC 2N_2H_6(ClO_4)_2 \rightarrow 8NH_4ClO_4 +42H_2O + 26HClO_4 + 14N_2O + 7Cl_2 + 6N_2 + H_2$ The solid state decomposition up to $180^oC$ ensues with an activation energy of 23 kcal/mole whereas above $180^oC$ in the molten state the activation energy is 35 kcal/mole.
