Notes:
The kinetics and mechansim for the NO2-initiated oxidation of tetramethyl ethylene (TME) have been studied using the FTIR spectroscopic method in mixtures containing NO2 and TME (0.1-1.0 Torr) and N2—O2 (700 Torr) at 298 ± 2 K. While TME decayed according to -d[TME]/dt = kobs[NO2][TME], NO2 exhibited a complex kinetic behavior. Furthermore, values of kobs were dependent on [O2]. Among the products were (CH3)2CO and at least three NO2-containing compounds. These results indicate the formation of a nitro-alkylperoxy radical via reactions (1), (-1), and (2), and its subsequent reactions leading to the observed products. The [O2]-dependence of kobs yielded k1 = (1.07 ± 0.15) × 10-20 cm3 molecule-1 S-1 and k-1/k2 = (3.54 ± 0.61) × 1018 molecule cm-3.
