Abstract
The branched chain isothermic consumption of NF2 radicals in mixtures of oxygen with C2H6, C3H8, and C2H4 was found. The branched chain natu re of the consumption of minor amounts of NF2 (P(NF2) approximately 10 (-3) torr) was observed at 300 - 700 K under a total pressure of 2 - 2 5 torr in the reactor and partial PresSures Of O2 and hydrocarbons of 0.1 - 20 torr. A closed region of isothermic selfignition was experime ntally established for the first time for branched chain reactions (in the system NF2 + O2 + C3H8). The simplified mechanism, allowing a qua litative explanation for the presence of the region of the spontaneous ignition of NF2 additives in the system C3H8 + O2, is proposed.
