AI Technical Summary
Existing technologies for synthesizing trifluoroacetyl fluoride and carbonyl fluoride suffer from problems such as complex equipment, cumbersome processes, numerous byproducts, low yields, and insufficient safety, especially the risk of runaway reactions during industrial-scale production.
A gas-phase reaction method is used to react hexafluoropropylene or hexafluoropropylene oxide with oxygen and diluent compounds in a reactor made of nickel or nickel alloy. By controlling the reaction conditions and the gas contact surface, side reactions are suppressed and the yield of the products is improved.
This technology enables a simple and safe industrial production of trifluoroacetyl fluoride and carbonyl fluoride, avoiding the use of photoreactors and specific hydrogen fluoride adducts, and improving the yield of the products and production safety.
