Rates and Mechanisms of Formaldehyde Pyrolysis and Oxidation,
Abstract
Pyrolysis and oxidation rates of formaldehyde have been measured behind reflected shock waves for 1200 < or = T, K < or = 2200 and 1.8 < or = p, atm < or = 2.7, in mixtures of CH2O/Ar and of CH2O/N2O/CO/Ar, respectively. Concentrations of CH2O were monitored by absorption of HeXe laser radiation at 3.508 microns, as well as by CH2O emission in the infrared. Emissions from CO2, H2O, and CO-O recombination radiation were monitored in the oxidation experiments; CO emission was monitored during pyrolysis. To account for pyrolysis at late times, it was necessary to allow for direct reaction between H2 and CH2O. The 19-step reaction mechanism describes our observed oxidation rates satisfactorily.
