Patent ID: 7750195

Claim:
A process for obtaining a hydrofluoroalkane selected from the group consisting of 1,1,1,3,3-pentafluoropropane, 1,1,1,3,3-pentafluorobutane, 1,1,1,3,3,3-hexa-fluoropropane (HFC-236fa), 1,1,1,2,3,3,3-heptafluoropropane (HFC-227ea) and 1,1,1,2,3,4,4,5,5,5-decafluoropentane (HFC-43-10mee), which is purified of organic impurities which contain at least one hydrofluoroalkene, according to which the hydrofluoroalkane containing organic impurities is subjected to a purification treatment comprising an adsorption onto a solid adsorbent.
