THE PHOTOLYSIS OF ORGANIC-SUBSTANCES UNDER ATMOSPHERIC CONDITIONS WITH A CYLINDRICAL PHOTOREACTOR USING ETHYL NITRITE AND NITROGEN-DIOXIDE

The first-order rate constants of 8 organic substances were measured using the ethyl nitrite and nitrogen dioxide photolyses and their relative rates with respect to n-hexane rate constant were calculated. These were compared with literature data. Relatively small photolysis rates of alkane and aromatics were shown for our photosystems and the alkenes were rapidly photolyzed. For mixed photooxidation reactions of various organics, it would be reasonable for organics of the group classified by their molecular structures to be discussed on their reactivities with OH radicals.
