Abstract
A process for producing halogenated derivatives of methane containing at least one fluorine atom comprises reacting a gaseous mixture containing Cl2 and CH4 with a solid fluorinating agent comprising CaF2 for a contact time of less than three minutes at a temperature of from 180 DEG to 700 DEG C. When a fixed bed is used, the particle size of the fluorinating agent is preferably from 1 to 20 mm. while when a fluidized bed of the solid fluorinating agent is used, the particle size is preferably below 14 mesh Tyler and more especially from 42 to 400 mesh Tyler. The chlorides or fluorides of Cr, Ni, Co, Al, Ga, V, Zr, Th, Zn, Fe, Pd, Cu, Bi or Pb may be used as catalysts. Examples describe the production of mixtures containing one or more of CF3Cl, CF2Cl2, CFCl3, CHFCl2, CHF3 and CHF2Cl.
