Abstract : To aid in the development of boron-enhanced fluoronitramino explosives, the kinetics of individual reactions have been measured over wide temperature ranges. Results obtained are, for BO + O2 right arrow BO2 + O (1) k(298 - 960 K) = 7.9x10(exp -12) exp(161 K/T) and for BO + HCl right arrow products (2) k(293 -760 K) = 6.3x10(exp -13) exp(-1403 K/T), both in units of cu cm /molecule /s. Upper limits are found for BO + CO2 right arrow BO2 + CO (3). Reactions (1) and (2) have pre-exponentials two orders of magnitude smaller than the corresponding AlO reactions. Evidence is presented suggesting that all six reactions proceed through intermediate complexes, which for BO are thought to readily dissociate back to the reactants. This would explain why reaction (3) is too slow for observation. That reaction, and its reverse, were considered as very sensitive in models for B/O/H/C system combustion.
