PRODUCTION OF LIQUID ORGANIC FLUORIDE AND APPARATUS FOR PRODUCING THE SAME

PROBLEM TO BE SOLVED: To provide a means for efficiently producing a desired fluoride, especially a perfluoro compound in high yield by fluorinating a partially fluorinated organic compound and to provide a reactional apparatus therefor. SOLUTION: A fluorine-containing gas is fed from the bottom of a reactional apparatus having a structure in which a tank-shaped reactional zone is connected to the top of a columnar reactional zone so that gas and liquid flow can be carried out and the internal pressure of the tank-shaped reactional zone is weighted to the internal pressure of the columnar reactional zone and the ratio (V2/V1) of the internal volume (V2) of the tank-shaped reactional zone to the internal volume (V1) of the columnar reactional zone has a relationship of 0.2-2. A liquid organic compound having carbon-hydrogen bonds is fed to the tank-shaped reactional zone at the top and the liquid is kept in a uniformly mixed state in the tank-shaped reactional zone. The liquid flowing down to the columnar reactional zone flows down as a piston flow in the column while being brought into contact with the fluorine-containing gas and then discharged from the bottom of the columnar reactional zone.
