Beschreibung
Zusammenfassung:	Purified 1,1,1,3,3-pentafluorobutane (HFC-365 mfc) with low contents of hydrogen chloride, hydrogen fluoride and/or unsaturated impurities is obtained from the crude compound by treatment in the liquid phase with a solid inorganic sorption agent or with diatomic molecules capable of addition to C-C multiple bonds, followed by separation. Independent claims are also included for: (a) HFC-365 mfc containing not more than 1 ppm HF, 1 ppm HCl , 20 ppm unsaturated (chloro)-fluoro compounds and 10 ppm unsaturated 2C compounds; (b) the use of fluorotrichloroethylene (CFC1111) as a control substance for monitoring the purification of HFC-365 mfc containing CFC1111 and other unsaturated compounds as impurities.
