as a diluent barely affected the decomposition). The decomposition was found
to occur in two stages.
The first stage is characterized by relatively high reaction rates (the heat release is
about 2.7 kJ/g of the reagent). In the second stage, decomposition of the condensed
residue occurs with significantly lower (by about two orders of magnitude) rates.
