Shock Tube and Modeling Study of the Monomethylamine Oxidation at High Temperature

Monomethylamine, Ignition, Shock tube, Nitrogen oxides
The ignition of monomethylamine was studied in reflected shock waves over the temperature range of 1255- 1579 K and the pressure range of 1.04-1.51 bar. The ignition delay time was measured by the sudden increase of pressure profile and the radiation emitted by OH radicals. The relationship between the ignition delay time and the concentrations of monomethylamine and oxygen was determined in the form of mass-action expressions with an Arrhenius temperature dependence. In contrast to the behavior observed in hydrocarbons, monomethylamine acts to accelerate rather than inhibit its own ignition. And numerical modeling of the ignition of CH3NH2 has also been carried out to test the several kinetic mechanisms.
