Abstract : The high temperature pyrolysis of simple organic molecules, CH4, CCl4, CF4 and C2H2 has been studied in a shock tube. Under conditions where the final equilibrium composition is almost entirely atomic, the C2 molecule is observed to rise to a peak and thereafter decline, apparently at the same rate as the original compound is decomposing. Absolute intensity measurements on the peak C2 yield indicate that as much as 20% of the carbon atoms can form C2. By following the decay of the C2, the overall rates of decomposition of the organic materials have been obtained. The formation of C2 can be explained in terms of the reaction type CX + C yielding C2 + X. (Author)
