| Abstract: | This study utilizes long-path Fourier transform infra-red spectroscopy to examine the photooxidation of methanol by chlorine atoms and the subsequent fate of the hydroxymethyl radical produced in the reaction.At one atmosphere under oxygen rich conditions (20%), the hydroxymethyl radical undergoes an abstraction reaction with oxygen to form formaldehyde and hydroperoxyl radicals rather than an addition reaction to produce peroxyhydroxymethyl radicals.The rate constant for Cl + HCOOH was determined to be 8.9 × 10−12 cm3 molecule−1 s−1. |
