摘要

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.
