Documented Uses

• Stable inhalation anesthetic; [ChemIDplus]
• Used for the induction and maintenance of general anaesthesia during surgery and cesarean section and also used for analgesia during vaginal delivery.
• Enflurane is prepared by dichlorination of the methyl group of 1-chloro-1,2,2-trifluoro-2- methoxyethane and replacement of these two chlorine atoms by fluorine.
• ... Prepared by successive chlorination and fluorination of the hydrocarbon ether.
• Prepn: Terrell, GB patent 1,138,406, US patent 3,469,011, US patent 3527813 (1969, 1969, 1970 all to Air Reduction)
• Fluorinated greenhouse gases (fluorinated GHGs) are man-made gases used in several sectors. They include hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur hexafluoride (SF6), nitrogen trifluoride (NF3), and a number of fluorinated ethers. Fluorinated GHGs also include chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs), but these ozone-depleting substances (ODSs) are currently being phased out and otherwise regulated under the Montreal Protocol and Title VI of the Clean Air Act, and EPA is not
