Identification of Reaction Intermediates in Combustion Reactions Involving Halocarbon Flame Retardants

摘要

The pyrolysis of some perfluoro organic iodides have been used to prepare free radical species, of possible importance in flame inhibition chemistry, for infrared matrix isolation studies. The species CF3O2, C2F5, n-C3F7 and iso-C3F7 were identified and vibrational assignments made. For CF3O2, oxygen isotope studies were used to help in the vibrational assignments. Papers for publication have been prepared describing this work and are included in this report. Normal coordinate analyses for CF3O2 and C2F5 are currently in progress and will be submitted for publication in 1980. Preliminary data from these calculations strongly support the initial vibrational assignments made for CF3O2 and C2F5. Attempts were made to identify the species CF3O, t-C4F9, C6F5 and C6F5O2. Some evidence for the existence of CF3O was found but was not definitive. The results of these latter studies are described in the first section of this report. (Author)
