Evaluation of Kinetic and Mechanistic Data for Modeling of Photochemical Smog

This review is a critical evaluation of the rate constants, mechanisms, and products of selected atmospheric reactions of hydrocarbons, nitrogen oxides, and sulfur oxides in air. The evaluation considers eight hydrocarbons (n-butane, 2,3-dimethylbutane, ethene, propene, 1-butene, trans-2-butene, toluene, and m-xylene) for which smog chamber irradiations have been carried out under carefully controlled conditions and which have been the subject of computer modeling studies by more than one research group. The reactions involved are treated in the following categories: inorganic reactions in organic-NOx-air irradiations; organic reactions of the formaldehyde-NOx-air system; organic reactions of the acetaldehyde-NOx-air system; organic reactions of the alkene-NOx-air systems; organic reactions of the alkane-NOx-air systems; organic reactions of selected carbonyl-NOx-air systems; organic reactions of the aromatic-NOx-air systems; combination reactions of peroxy radicals, and homogeneous gas phase SO2 reactions. This report considers literature through early 1983.
