摘要:In the synthesis of 1,1,1,3,3-pentafluoropropane (R-245fa), a mixture of R-245fa and the impurity 1-chloro-3,3,3-trifluoropropene (R-1233zd) is purified and R-1233zd is removed from the mixture by contacting the mixture with 1-5 mols of chlorine for each mol of R-1233zd in the presence of ultraviolet light having a wavelength between about 300 to 400 nm which provides at least 0.02 watts-hour/kg of the mixture, the R-1233zd being reduced to below 10 wt. ppm or lower, as it is converted to 1,2,2-trichloro-3,3,3-trifluoropropane (R-233) or other propane which contains more chlorine and which has a higher boiling point than R-245fa and can be separated easily from R-245fa, the photochlorination being effected in a manner such that at least about 96 wt. % of the starting amount of R-245fa is maintained in the mixture.

标 题 :Catalyst synthesis of halogenated compounds with catalyst regeneration with elemental halogen
发明人：BRAUN MAX; BROSCH CARSTEN
权利人:SOLVAY FLUOR & DERIVATE
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 This is preferably achieved by withdrawing part of the reaction mixture from the reactor, mixing the withdrawn part with chlorine or fluorine in order to regenerate the catalyst, and thereafter returning the withdrawn part to the reactor.
