Abstract

The reaction probability of CH~3~O~2~ radicals with NO~2~, CH~4~, C~3~H~6~, and CH~3~CHO on the solid surface of KCl in flow at low pressure and temperature range of 297–353 K has been studied. The chosen conditions allowed excluding homogeneous interaction of radicals. The heterogeneous radical decay of peracetic acid served as a source of CH~3~O~2~ radicals.

On the basis of ESR measurements of CH~3~O~2~ radicals with the above‐mentioned compounds, a heterogeneous reaction mechanism has been identified.

The reactivity of NO~2~ was greatest for the compounds studied.

The effective activation energy was evaluated to be 10.4 Β± 0.8 kJ/mol for the reaction of RO~2~ radicals with NO~2~ and βˆ’21.3 Β± 2.8 kJ/mol for methane. Β© 2004 Wiley Periodicals, Inc. Int J Chem Kinet 36: 591–595, 2004
