Specification
Carbonyl fluoride with cas registry number of 353-50-4 is pungent colorless gas. It is also called for Carbon difluoride oxide ; Carbon fluoride oxide (COF2) ; Carbon oxyfluoride (COF2) ; Carbon oxyfluoride ; Carbonic difluoride ; Carbonyl difluoride ; Carbonyl oxyfluoride ; Difluoroformaldehyde ; Difluorooxomethane ; Fluophosgene ; Fluoroformyl fluoride ; Fluorophosgene ; HSDB 6010 ; RCRA waste number U033 . It is unstable in the presence of water and incompatible with water , bases (including amines), oxidizing agents, alcohols. When heated to decomposition, it yields carbon monoxide gas and fluorine . It may react vigorously if mixed with diisopropyl ether or other ethers in the presence of trace amounts of metal salts and reacts violently with hexafluoroisopropylideneaminolithium. It can be used for the production of fluorine plastics.
