The individual hydrocarbons such as methane, propane, 1-butene, 1, 3-butadiene, ethylene, and the mixtures of these hydrocarbons and nitrogen dioxide were irradiated with xenon lamp or solar light under static conditions. Major products resulting from photo-oxidation of them were identified by long-path infrared spectrophotometer. The concentrations of the products were determined by gas chromatography for hydrocarbons, and long-path infrared spectrophotometry for hydrocarbons and ethyl nitrate, and non-dispersive infrared analyzer for carbon monoxide, and colorimetry for formaldehyde, respectively. From these experiments, it was found that the saturated hydrocarbons are relatively stable to the photo-oxidation and yield small amounts of the products such as carbon monoxide, formaldehyde, ethyl nitrate, etc., whereas the unsaturated hydrocarbons which are highly reactive yield large amounts of the products.
