- Description
- Gas phase reaction of CHF₃ with CH₄, and the effect of additives such as CBrF₃ and CH₃OH on the reaction, have been investigated in the temperature range of 800–1100 K. The major products detected include CH₂double bond; length as m-dashCF₂ and C₂F₄ under all conditions studied. The presence of small amounts of CBrF₃ and CH₃OH enhances the conversion of CH₄ and rate of formation of CH₂double bond; length as m-dashCF₂ significantly, while concomitantly the rate of formation of C₂F4 decreases. The experiments were modeled against a comprehensive reaction mechanism involving 90 species and 790 reactions. Based on the experimental observations and reaction modeling, the crucial steps influencing the conversion of CHF₃ and CH₄, the formation of major and minor products and the promoting effects of CBrF₃ and CH₃OH are fully elucidated. For comparative purposes, the reaction of CHClF₂ with CH₄ under similar conditions is also studied and the results are consistent with the reaction mechanism developed and discussed.
