The object of this work was the investigation of the photochemical oxidation of formaldehyde in the gaseous phase at 110°C. Reaction mixtures, where the O2: CH₂O ratio was approximately 1:10, were irradiated with ultra violet light at a wavelength of 3130A⁰ and the reaction products analyzed. The major products were found to be CO, H₂ and HCOOH. CO₂ was a minor product. No peroxides were found and the reaction was oxygen independent at low O₂:CH₂O ratios.
The formation of the major products was found to be directly proportional to the initial formaldehyde pressure and to the intensity of the absorbed light.
A satisfactory mechanism is proposed to explain the formation of the reaction products, and the following kinetic equations were derived:
