摘要： Catalysts such as antimony halides, which are useful in fluorination reactions involving hydrogen fluoride, may be reduced during the reaction and require regeneration. Regenerative oxidation is usually carried out by introducing elemental halogen, preferably fluorine or chlorine, into the reaction mixture. In accordance with the invention elemental halogen is prevented from coming into contact with starting materials or intermediate products which are reactive therewith. This is preferably achieved by withdrawing part of the reaction mixture from the reactor, mixing the withdrawn part with chlorine or fluorine in order to regenerate the catalyst, and thereafter returning the withdrawn part to the reactor.

摘要： A process is disclosed for the separation of a mixture of HF and CF.sub.3 CClFCF.sub.3. The process involves placing the mixture in a separation zone at a temperature of from about -30.degree. C. to about 100.degree. C. and at a pressure sufficient to maintain the mixture in the liquid phase, whereby an organic-enriched phase comprising less than 50 mole percent HF is formed as the bottom layer and an HF-enriched phase comprising more than 90 mole percent HF is formed as the top layer. The organic-enriched phase can be withdrawn from the bottom of the separation zone and subjected to distillation in a distillation column to recover essentially pure CF.sub.3 CClFCF.sub.3. The distillate comprising HF and CF.sub.3 CClFCF.sub.3 can be removed from the top of the distillation column while essentially pure CF.sub.3 CClFCF.sub.3 can be recovered from the bottom of the distillation column. The HF-enriched phase can be withdrawn from the top of the separation zone and subjected to distillation in a distillation column. The distillate comprising HF and CF.sub.3 CClFCF.sub.3 can be removed from the top of the distillation column while essentially pure HF can be recovered from the bottom of the distillation column. If desired, the two distillates can be recycled to the separation zone.Also disclosed are compositions of hydrogen fluoride in combination with an effective amount of CF.sub.3 CClFCF.sub.3 to form an azeotrope or azeotrope-like composition with hydrogen fluoride. Included are compositions containing from about 38.4 to 47.9 mole percent CF.sub.3 CClFCF.sub.3.Also disclosed are processes for producing 1,1,1,2,3,3,3-heptafluoropropane. One process uses a mixture comprising HF and CF.sub.3 CClFCF.sub.3 and is characterized by preparing essentially pure CF.sub.3 CClFCF.sub.3 as indicated above, and reacting the CF.sub.3 CClFCF.sub.3 with hydrogen. Another process uses an azeotropic composition as described above, and reacts the CF.sub.3 CClFCF.sub.3 with hydrogen in the presence of HF.Also disclosed is a process for producing hexafluoropropene. This process is characterized by preparing essentially pure CF.sub.3 CClFCF.sub.3 as indicated above, and dehalogenating the CF.sub.3 CClFCF.sub.3.
