Abstract

A method for preparing fluorinated organic compounds wherein at least one fluorinated olefin is reacted with methyl fluoride in the gas-phase and in the presence of a Lewis Acid catalyst to form at least one product having at least 3 carbon atoms.

Claims (9)

1. A method of preparing fluorinated organic compounds comprising reacting methyl fluoride with at least one fluorinated olefin having the structure:

wherein R is F, Cl, C 1 -C 2 fluorinated alkyl, or two-carbon fluorinated alkenyl,

to produce at least one product having at least 3 carbon atoms, wherein said reaction occurs in the gas-phase and in the presence of a Lewis Acid catalyst, wherein said product includes a fluorocarbon polymer.

2. A method of preparing fluorinated organic compounds comprising reacting methyl fluoride with at least one fluorinated olefin having the structure:

wherein R is F, Cl, C 1 -C 2 fluorinated alkyl, or two-carbon fluorinated alkenyl,

to produce at least one product having at least 3 carbon atoms, wherein said reaction occurs in the gas-phase and in the presence of a Lewis Acid catalyst, wherein said product includes 2,3,3,3-tetrafluoro-1 -propene.

3. A method of preparing fluorinated organic compounds comprising reacting methyl fluoride with at least one fluorinated olefin having the structure

wherein R is F, Cl, C 1 -C 2 fluorinated alkyl, or two-carbon fluorinated alkenyl, to produce at least one product having at least 3 carbon atoms, wherein said reaction occurs in the gas-phase and in the presence of a Lewis Acid catalyst, wherein said Lewis Acid catalyst is impregnated on activated carbon.

4. The method of claim 3 wherein said activated carbon is essentially anhydrous.
