Abstract

The interaction of CF₃OCF₂OCF₃ on Al₂O₃ surface was investigated by Fourier transform infrared (FTIR) under both `vacuum' and `pressure' conditions. It was found that CF₃OCF₂OCF₃ decomposed only under `pressure' conditions. Fluoroformate FCOO (ads) was formed and stayed adsorbed on the surface up to 550 K. The reactivities of CF₃OCF₂OCF₃ and CF₃OCF₃ on Al₂O₃ surface are compared and the reaction mechanisms are also discussed.
