Abstract
A method of producing perfluorocarbon halides in a one-pot reaction is described. The method employs a perfluorocarbon acid, a first halogenating agent and a second halogen which drives the reaction forward. Novel perfluorocarbon halides and a direct method for producing perfluorocarbon hypohalites also are described.
Claims24
A method of producing a perfluorocarbon halide, comprising:
- providing a perfluorocarbon acid;
- contacting the perfluorocarbon acid with a first halogenating agent in the presence of a second halogen which drives the reaction such that a perfluorocarbon halide is formed.
A method of producing a perfluoroalkyl halide comprising:
- providing a perfluorocarbon acid and a first halogenating agent,
- pre-mixing a second halogen and a diluent together forming a premixture, and
- introducing the premixture to the perfluorocarbon acid and the first halogenating agent to form a reaction amalgam such that a perfluoroalkyl halide is formed in a single step reaction.
A method of producing a perfluoroalkyl halide comprising:
- providing a perfluorocarbon acid and a first halogenating agent,
- dissolving the perfluorocarbon acid and the halogenating agent in a solvent,
- pre-mixing a halogen and a diluent together forming a premixture,
- introducing the pre-mixture to the dissolved perfluorocarbon acid and halogenating agent, and
- performing the reaction at a temperature between about -20.degree. C. and about 100.degree. C. such that a perfluoroalkyl halide is formed in a single step reaction.
A method of producing a perfluoroalkyl halide comprising:
- providing a pre-mixture of a perfluorocarbon acid and a first halogenating agent forming a premixture, and
- introducing a second halogen to the pre-mixture to directly form a perfluoroalkyl hypohalite prior to forming the perfluoroalkyl halide.
A method for producing a perfluorocarbon hypohalite directly from perfluorcarbon acids, comprising:
- providing a perfluorocarbon acid;
- and
- contacting the perfluorocarbon acid with a halogenating agent in the presence of elemental fluorine such that a perfluorocarbon hypohalite is directly formed.
