Waves: Kinetic Modeling of the H + CH2O Reaction Rate

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 (58). The
result from modeling 34 sets of data gave rise to k(58)=10^13.46 exp(-1879/T)
cm3/mol s over the entire temperature range studied. A nonlinear least-squares
analysis of these high temperature data and all published low temperature
(T¾1000 K) values led to k(58)=10^8.10 T^1.62 exp (-1089/T) cm3/mol s,
covering T from 260 to 1700 K.
