✦ Synopsis

The light-induced oxidation of methanol and related compounds in aqueous solution was studied using the conductometric method and gas chromatography. Photolysis of methanol by polychromatic IJV light (A > 200 nm) leads to the formation of formic acid and methylformate. The effects of the structure of the alcohol, its concentration, the presence of oxygen in the illumimated solution and other factors on the rate of the process were studied. A possible route for the photoprocess is discussed. The proposed mechanism involves the interaction of the intermediately formed photoexcited aldehyde with molecular oxygen, leading to the respective biradical.

It is assumed that its conformational peculiarities favour the formation of the final product.
