ATMOSPHERIC CHEMISTRY OF ANILINE, N,N-DIMETHYLANILINE, PYRIDINE, 1,3,5-TRIAZINE, AND NITROBENZENE

The atomospherically important reactions of aniline, N, N-dimethylaniline, pyridine, 1,3,5-triazine, and nitrobenzene, chosen as model compounds for a series of industrially and agriculturally important chemicals, have been studied with the OH radical, O//3, and gaseous HNO//3 by a variety of experimental techniques. At room temperature, rate constants (in cm**3 molecule** minus **1 s** minus **1) were obtained for these gas-phase reactions and are given in the paper. Under atmospheric conditions, the O//3 reactions are calculated to be of negligible importance. The implications of teh OH radical and HNO//3 reactions for the atmospheric lifetimes of these nitrogen-containing organic compounds are discussed.
