✦ Synopsis

The reactions of naphthalene in Nz05 -NO3 -NOz -Nz -O2 reactant mixtures have been investigated over the temperature range 272-297 K at ca. 745 torr total pressure and at 272 K and ca. 65 torr total pressure using long pathlength Fourier transform infrared absorption spectroscopy. 2,3-Dimethyl-2-butene was added to the reactant mixtures at 272 K to rapidly scavenge the NO3 radicals both initially present in the added Nz05 and formed from the thermal decomposition of NzO5 during the reactions. The data obtained in the presence and absence of added 2,3-dimethyl-2-butene showed that napthalene undergoes initial reaction with the NO3 radical to form an NO3-naphthalene adduct, which either rapidly decomposes back to the reactants (at a rate of ca. 5 x lo5 s-' at 298 K) or reacts exclusively with NO2 to form products. When NO3 radicals, NzOs and NO2 are in equilibrium, this overall process is kinetically equivalent to reaction of naphthalene with NzOs, and previous kinetic and product studies have indeed assumed the reactions of naphthalene and alkyl-substituted naphthalenes in N205 -NO3 -NO2 -air mixtures to be with N205, and not with NO3 radicals.

Recent experimental results on the thermal decomposition of N205 in N2 are evaluated in terms of unimolecular rate theory. A theoretically consistent set of fall-off curves is constructed which allows to identify experimental errors or misinterpretations. Limiting rate constants k o = "21 2.2 X lo-:
