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： 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.
