    摘要： A process for purification of 1,1,1,3,3-pentafluorobutane (HFC-365mfc) containing a decreased amount of hydrogen chloride, hydrogen fluoride and/or unsaturated impurities. To this end crude 1,1,1,3,3-pentafluorobutane is treated in the liquid phase with a solid, inorganic sorption agent and/or with diatomic molecules which and to C—C multiple bonds. The product to be purified is preferably treated with elemental fluorine. The contents of hydrogen chloride and hydrogen can each be decreased to below 1 ppm. The content of unsaturated (chlorine)-fluorine-compounds can be decreased to below 20 ppm, and the content of unsaturated C2 compounds can be decreased to below 10 ppm. It has also been discovered that fluorotrichloroethylene can be used as a control substance to monitor the purification of 1,1,1,3,3-pentafluorobutane.

    摘要： A process for preparing purified, saturated, partially fluorinated or perfluorinated hydrocarbon compounds from crude products which are contaminated with impurity compounds which absorb light at a wavelength of &lgr;>200 nm by irradiating the crude product with UV radiation of a wavelength of &lgr;>200 nm and thereafter recovering highly pure, partially fluorinated or perfluorinated hydrocarbon compounds from the irradiated reaction product, for example, by simple vacuum distillation.

    摘要： Inorganic and organic compounds containing fluorine can be produced, for example, from corresponding chlorine-containing compounds by chlorine/fluorine exchange using fluorinating agents. Monocyclic or bicyclic compounds containing at least two nitrogen atoms, at least one of which is incorporated into the ring system, can be used as catalysts or fluorinating agents for chlorine/fluorine exchange reactions to produce sulfurylchlorofluoride, sulfurylfluoride or a carboxylic acid fluoride. It is likewise possible to carry out HF addition to unsaturated carbon-carbon bonds or chlorine/fluorine exchange at carbon atoms. For example, monochloro or dichloro malonic acid esters can be converted to difluoro malonic acid esters. Work-up of the reaction mixture can be simplified by using suitable solvents which force the reaction mixture to exist in two phases.

    摘要： A method of producing alkanes containing chlorine by addition of chlorine to C—C double bonds or C—C triple bonds or by exchange of hydrogen for chlorine by contacting the starting compound in the gas or liquid phase with elemental chlorine and irradiating the reaction mixture with UV light having a wavelength of λ≧280 nm. In this way pentachloroethane can be produced from trichloroethylene, CFC-113 from HCFC-123 or HFC-133a, CFC-112a from HCFC-142b, or HCFC-123 from HCFC-133a. The method also is suitable for separating photochlorinatable impurities from HFC-365-mfc to obtain purified HFC-365-mfc. Advantages include high yields and excellent selectivity.

    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.
