Abstract

The reaction between $CH_3$ radicals and $O_2$ was investigated in incident shock waves at temperatures between 1390 and 2250 K and densities from 1.5 to 5.3 mol/$m^{+30/3}$ using azomethane as a source of methyl radicals by following the consumption of CH3 radicals with time resolved UV absorption measurements at 213.9 nm. The rate constant expression $k_2=1.35{\times}10^{12}\;exp( - 5900 K/T)\;cm^3 mol^{-1}s^{-1}$ for the reaction of $CH_3 + O_2{\rightarrow}CH_2O + OH$ was derived.

메틸 라디칼과 산소 분자 사이의 반응 속도를 입사 충격파를 이용하여 1390부터 2250k 온도범위 및 1.5에서 5.3mol/$m^3$ 밀도 범위에서 213.9nm 파장에서의 메틸 라디칼의 흡수 스펙트럼을 측정하여 고찰하였다. 메틸 라디칼을 생성하기 위한 원천 분자로는 azomethane이 사용되었다. 실험 결과 $CH_3 + O_2{\rightarrow}CH_2O + OH$ 반응의 속도상수는 $k_2=1.35{\times}10^{12}\;exp( - 5900 K/T)\;cm^3 mol^{-1}s^{-1}$ 같이 표현할 수 있었다.
