Abstract
A method to stably produce trifluoroethylene with a high selectivity by reacting 1,1,1,2-tetrafluoroethane with a solid reactant and suppressing the formation of by-products such as polymer carbon is provided. In the method, a material gas containing 1,1,1,2-tetrafluoroethane passes through a layer consisting of a particulate solid reactant having an average particle size of from 1 μm to 5,000 μm to bring the solid reactant and 1,1,1,2-tetrafluoroethane into contact with each other in a state where the layer consisting of the solid reactant is fluidized.

A method for producing trifluoroethylene, the method comprising:
- passing a material gas containing 1,1,1,2-tetrafluoroethane through a layer consisting of a particulate solid reactant having an average particle size of from 1 μm to 5,000 μm to bring the solid reactant and 1,1,1,2-tetrafluoroethane into contact with each other in a state where the layer consisting of the solid reactant is fluidized,
- wherein
- the solid reactant contains at least one metal compound selected from the group consisting of a metal oxide, a metal hydroxide, a metal carbonate, a metal sulfate, and a metal halide,
- the metal species contained in the metal compound is at least one metal selected from the group consisting of an alkali metal, an alkaline earth metal, a group 13 metal, and a group 14 metal, and
- a linear flow velocity of the material gas is from 1 cm/s to 1,000 cm/s.
