Abstract
The reaction between excess atomic oxygen and formaldehyde in the gas phase has
been studied in a flow system at 300 K using product analysis, e.p.r. and
chemiluminescence. The initial step (15) has a rate coefficient of
(9.0±1.0)E+10 cm3/mol s. By comparing the reaction products with those of
reaction of oxygen atoms with ethylene where the initial steps are reactions (10) and (25), it is shown that the relative
constants of subsequent reactions (13), (14), and (55) are in the ratio
k(13):k(14):k(55)=0.54:0.46:4.0
