An overview of the gas-phase reactions responsible for the photooxidation of air pollutants is provided. Starting with an introduction to the field of atmospheric chemistry we proceed to discuss the concept, and utility, of atmospheric lifetime. The processes responsible for the degradation of alkanes, alkenes, aromatics, NOx, SOx, CFCs and their replacements...
This chapter provides an overview of the atmospheric photochemical degradation of important anthropogenic molecules. Starting with an introduction to atmospheric chemistry, the concept of atmospheric lifetime is presented and the degradation mechanisms of alkanes, aromatics, nitrogen oxides, SO2, chlorofluorocarbons, halons, hydrofluorocarbons, and hydrochlorofluorocarbons are discussed. Areas of...
The rate constant of the reaction Cl + CH3OH (k1) has been measured in 500–950 Torr of N2 over the temperature range 291–475 K. The rate constant determination was carried out using the relative rate technique with C2H6 as the reference compound. Experiments were performed by irradiating mixtures of CH3OH, C2H6, Cl2, and N2 with UV light from a fluorescent lamp whose intensity peaked near 360 nm....
