Description:

The Bureau of Mines used molecular beam-mass spectrometry to determine the microstructure of a 10.1% Ch4-21.2% O2-67.6% Ar-1.1% Cf3br inhibited flame and its uninhibited analog, both stabilized at 32 torr on a cooled flat-flame burner. Composition profiles of atomic, radical, and stable species and temperature profiles for both flames were obtained and compared. Kinetic analyses of the profiles yielded values for the rate coefficients of several elementary methane flame reactions and information on the reactions of formation and decay of the observed halocarbon species. Cf3br is judged to decay by thermal decomposition as well as by abstraction reactions, and the fluorocarbon chemistry occurring in the inhibited flame is due primarily to cf2 radical reactions. Rate coefficients and mechanisms for reactions of the inhibitor-related species are given. [Description provided by NIOSH]
