Abstract:
A process for producing a fluorinated organic compound comprising:reacting an organic starting material with a fluorination agent in a fluoropolymer-lined reactor in the presence of a liquid-phase catalyst to produce a vaporized product stream;scrubbing said vaporized product stream using a liquid stream of scrubbing agent to form a recycle stream comprising a liquid mixture of scrubbing agent and condensed catalyst and and a low-catalyst content product stream having a substantially lower concentration of catalyst than said vaporized product stream, wherein the weight ratio of said liquid stream of scrubbing agent to said vaporized product stream is no greater than about 0.5:1;feeding a substantial portion of said recycle stream to said reactor; andrecovering said fluorinated organic compound from said low-catalyst content stream.
