Abstract

The desorption behaviour (desorption temperature and extent of desorption) of HF,HCFC-133a (CF₃CH₂Cl) and HFC-134a (CF₃CH₂F) on γ-AlF₃ or catalyst supported on γ-AlF₃ was studied using an adsorption apparatus and TG, DTA and DSC methods. On the basis of the results a reaction mechanism was proposed for the preparation of HFC-134a. The γ-AlF₃ employed for preparing the catalyst was expected to be stable below 550°C based on the crystalline phase transition temperature of γ-AlF₃.
