PRODUCTION OF BIS (FLUOROMETHYL) ETHER AND DIFLUOROMETHANE OF BIS (FLUOROMETHYL) ETHER AND DEFLUOROMETHANE

摘要

The present invention relates to a process for the preparation of bis (fluoromethyl) ethers which consists in contacting formaldehyde with a hydrogen fluoride in the presence of a solvent for an ether essentially immiscible with water. The bis (fluoromethyl) ether can be separated from the solvent by heating bis (fluoromethyl) ether at elevated temperature, preferably in the presence of a metal, metal oxide, metal fluoride or metal oxyfluoride catalyst, It can be converted to romentane.
