CHEMICAL KINETICS OF COF2 DECOMPOSITION IN SHOCK WAVES

Abstract

An infrared technique has been used to monitor the thermal decomposition of carbonyl fluoride (COF2) in argon and nitrogen diluent behind incident and reflected shock waves. Data was taken in the temperature range 2400 deg to 3600 deg K at total pressures between 0.2 and 26 atm. Direct sampling of reflected shock mixtures with a time-of-flight mass spectrometer provided knowledge of the decomposition products. The pressure and temperature dependence of the COF2 dissociation rate constants are discussed in terms of the Rice-Ramsperger-Kassel (RRK) unimolecular theory. Rate constants for the fluorine extraction reactions and COF disproportionation reaction were obtained by curve-fitting the complete COF2 kinetic histories with computed profiles. A chemical nonequilibrium stream-tube program which includes wall boundary layer effects was used for data analysis.
