Abstract

The structure of two premixed lean H~2~/O~2~/Ar flames, one uninhibited and the other inhibited by 3% of CF~3~H has been established at 4.6 kPa by using a mass spectrometric analyzer coupled with molecular beam sampling. The main effect of the CF~3~H addition concerns the formation of lower quantities of H atoms and the shift of the H, O, OH, H~2~O and temperature profiles in the inhibited flame. HF, CF~2~O and CO~2~ are products of the CF~3~H combustion. They remain in the burnt gases. CO is only an intermediate, which is formed essentially from CF~3~ species without going through CF~2~O as an intermediate.

With regard to the postulated intervention of phenylhydrazone structures during the degradation of 1,4-polyisoprenes by the phenylhydrazine (l)/oxygen system, UV, 'H NMR, 13C NMR and mass spectroscopy as well as steric exclusion chromatography were applied for the characterization of model phenylhyd
