Abstract

The branching ratio β = k1b/k1a for the formation of iso-propyl nitrate, i-C3H7ONO2, in the gas-phase reaction of i-C3H7O2 with NO, i-C3H7O2 + NO → i-C3H7O + NO2 (1a), i-C3H7O2 + NO → i-C3H7ONO2 (1b), was determined over the pressure range 55–500 Torr at 298 K using a high-pressure turbulent flow reactor coupled with a chemical ionization quadrupole mass-spectrometer. The β coefficient was found to increase linearly with pressure from about 0.6% at 55 Torr to about 3% at 500 Torr. The atmospheric implication of the results obtained is briefly discussed.
