Abstract
A fluorination reactor having a reaction zone, an inlet for supplying an organic compound to be fluorinated to the reaction zone, an inlet for supplying elemental fluorine to the reaction zone, and an outlet for recovering a fluorinated reaction product, wherein the reaction zone includes a fluoride-adsorbing composition for adsorbing any HF produced as a byproduct of the reaction between the organic compound and elemental fluorine.
Claims12
A first fluorination reactor comprising a reaction zone, an inlet for supplying an organic compound to be fluorinated to said reaction zone, an inlet for supplying elemental fluorine to said reaction zone, and an outlet for recovering a fluorinated reaction product, wherein said reaction zone comprises a fluoride-adsorbing composition and said reaction zone is configured so that said elemental fluorine contacts said organic compound in the presence of said fluoride-adsorbing composition and the amount of HF or another hydrogen-containing product produced as a byproduct of the reaction between said organic compound and said elemental fluorine is thereby reduced or eliminated, and wherein the distribution of reaction products is changed as a result of the reduction or elimination of the HF or another hydrogen-containing product;
- and
- a means for replenishing said fluoride-adsorbing composition, said means comprising:
- (a) a supply of an organic compound and a supply of elemental fluorine in communication with the respective inlets of said first reactor:
- (b) a second fluorination reactor comprising a reaction zone containing a fluoride-adsorbing composition essentially free of HF and respective inlets for supplying an organic compound to be fluorinated and elemental fluorine to said reaction zone of said second fluorination reactor;
- and (c) a means for switching said supply of said organic compound and said supply of elemental fluorine from said respective inlets of said first reactor to said respective inlets of said second reactor.
A system, comprising:
- a first fluorination reactor comprising:
- a reaction zone;
- an inlet for supplying an organic compound to be fluorinated to said reaction zone;
- an inlet for supplying elemental fluorine to said reaction zone;
- and an outlet for recovering a fluorinated reaction product, wherein said reaction zone comprises a fluoride-adsorbing composition for adsorbing any HF or other hydrogen-containing products produced as a byproduct of the reaction between said organic compound and said elemental fluorine;
- and
- a means for replenishing said fluoride-adsorbing composition, said means comprising:
- (a) a supply of an organic compound and a supply of elemental fluorine in communication with the respective inlets of said first fluorination reactor;
- (b) a second fluorination reactor comprising a reaction zone containing a fluoride-adsorbing composition essentially free of HF and respective inlets for supplying an organic compound to be fluorinated and elemental fluorine to said reaction zone of said second reactor;
- and (c) a means for switching said supply of said organic compound and said supply of elemental fluorine from said respective inlets of said first reactor to said respective inlets of said second reactor.
