✦ Synopsis

The pyrolysis of CF,H mixture, highly diluted with Ar, was studied over the temperature range 1150-I 570 K at pressures 1.5-2.6 atm behind reflected shock waves. The mechanism and the rate constant of CFXH pyrolysis at the high temperatures were discussed. The pyrolysis of CFgH was found to be interpreted well by two steps: (I) CF,HtM=CF,tHFtM and ( )

CF2tCF2 tM=C2F4t M. The rate constant expression k, = 1.3x 1016exp( -58.4 kcal/RI') cm3 mol-' s-l for the first reaction was determined.

The kinetics of the thermal decomposition of acetylacetone has been studied in a shock tube in the temperature range of 1120-1660 K. Detailed analyses of CO and H20 formation data indicate that HzO is formed by a four-center molecular channel, whereas CO is formed by the rapid dissociation of CH3C0
