Abstract

The preparation of CH₃F via vapor phase catalytic fluorination of CH₃OCH₃ promoted by AlF₃ (H-AlF₃, M-AlF₃, L-AlF₃) with different surface areas was investigated, with the reaction occurring as follows: CH₃OCH₃ +2 HF → 2CH₃F + H₂O. It was found that H-AlF₃ exhibited the highest catalytic activity with high stability among the three types of AlF₃ tested in the 100-h life-span test, which can be attributed to the massive amount of amorphous AlF₃ in H-AlF₃. H-AlF₃ contains the highest amount of acid and largest surface area among the AlF₃ species. The synthetic route of CH₃F showed higher conversion of raw material and better selectivity for CH₃F than traditional routes.
