Abstract

The formation of CF₃-CH₂F (HFC-134a) by catalytic hydrodechlorination of CF₃-CCl₂F (CFC-114a) has been studied utilizing the recent PulseTA® technique. Instead of hydrogen as reactant, deuterium was used which facilitates the detection of the reaction products, i.e. the discrimination of various hydrofluorocarbons (HFC), by mass spectrometry. The product composition confirms a reaction mechanism via the carbene CF₃-CF. Water traces which are retained in the channel structure of the catalyst interact with chemisorbed deuterium thus explaining the formation of hydrogenated fluorocarbons as well. The obtained results demonstrate the potential of the pulse technique for the investigation of solid state reactions.
