摘要: The direct fluorination of ethers in the presence of hydrogen fluoride (HF) scavengers such as sodium fluoride and potassium fluoride is disclosed. Ethers (liquid or solid) are either mixed with the HF scavenger, coated onto the HF scavenger or placed separately with the HF scavenger into a fluorination reactor and fluorinated by exposure to gradually increasing concentrations of fluorine gas. The HF scavenger permits use of more severe fluorination conditions i.e. higher initial fluorine, less gradual increases in fluorine gas concentrations and greater fluorine gas flow rates.
