Experimental investigation and modeling of the kinetics of CCl4pyrolysis behind reflected shock waves using high-repetition-rate time-of-flight mass spectrometry

Abstract

The pyrolysis kinetics of CCl₄ behind reflected shock waves was studied with high-repetition-rate time-of-flight mass spectrometry. For modeling, quantum mechanical calculations were performed to evaluate the dissociation energies of CCl bonds for the different CCl_x (x = 1 to 4) radicals. Good agreement with the JANAF thermochemical table was found. With the reaction mechanism developed for CCl₄ decomposition satisfactory agreement with experimental results was obtained. The investigations show the importance of C₂Cl₂ formation for understanding the processes of carbon cluster growth leading to carbonaceous particle formation.
