Single Pulse Shock Tube Studies on the Decomposition of C₂F₄ in the Presence of H₂

The decomposition of C₂F₄ in the presence of H₂ has been studied in asingle pulse shock tube.As the extend of the reaction C₂F₄+Ar→2CF₂+Ar is assigned to the measured concentration of the final stable product CH₄ led by the consequence of CF₂ insertion into H₂,the decomposition rate at temperature range 1000 to 1080K is consistent with the rate constant given by Modica and LaGraff.The direct measurements of the residuary concentration of C₂F₄ show that in addition to the direct pyrolysis there are 10 times more consumption of C₂F₄ caused by a polymerization chain initiated by the released H atom in the system as a consequence of the reaction of CF₂ with H₂.
