To predict photochemical smog potential of mixtures of hydrocarbon and hydrocarbon derivatives, it is necessary to establish whether component interactions affect behavior of individual components in the reaction system. This report covers work done at the Bureau of Mines, Bartlesville, Oklahoma, Petroleum Research Center, for the purpose of investigating olefin-aldehyde interactions possibly occurring in nox-sensitized photooxidation of 1-butene-aldehyde mixtures. First results showed that in such mixtures consumption of 1-butene is affected by the presence and nature of other hydrocarbons and/or aldehydes. Further investigation revealed that the effects of aldehydes on butene consumption could be explained in terms of effects on oxygen atom and ozone concentrations only during the later reaction stage following photooxidation of NO into NO2. In the earlier stages, the aldehyde effects can be explained only if olefin-radical reactions occur in parallel with the olefin-oxygen atom reaction.
