WebObserve the doubling of the enthalpy of H 2 O (–36 kJ/mole) because this compound has a stoichiometric coefficient of 2 in the reaction. The overall enthalpy of the reaction is –36 kilojoules, which means that the decomposition of 1 mole of ammonium nitrate releases 36 kJ of heat. The release of heat means that this is an exothermic reaction. Webpromotion of BPO decomposition to benzoyloxy radicals at lower temperatures and thus accelerated the copolymeriza-tion process. However, DMP-30 was a very sluggish pro-moter for BPO decomposition, probably due to the presence of both hydroxyl group, their ortho-position to two of three amine groups and their branched structure.
