Abstract

Mixtures of methyl nitrite and 1,3,5-trioxane have been pyrolyzed in shock waves at temperatures between 1180 and 1690 K. The rates of CO production measured by CO laser resonance absorption were kinetically modeled to obtain the rate constant for reaction (9): H + CH2O → CHO + H2. The result from modeling 34 sets of data gave rise to k9 = 1013.46exp(— 1879/T)cm3/mole-sec over the entire temperature range studied. A nonlinear least-squares analysis of these high temperature data and all published low temperature (T < 1000K) values led to k9 = 108.10T1.62exp(-1089/T)cm3/mole-sec, covering 260 ≤ T ≤ 1700K.
