摘要 |
<p>Process for obtaining a hydrofluoroalkane which is purified of organic impurities, according to which the hydrofluoroalkane containing organic impurities is subjected to at least one purification treatment chosen from
(b) a reaction with hydrogen fluoride
(c) a distillation in which the purified hydrofluoroalkane is removed from the top of the distillation column or from the side
(d) an extractive distillation
(e) an adsorption onto a solid adsorbent
(f) a reaction with a compound containing oxygen, and
(g) a reaction with a compound containing oxygen and a gas-phase reaction with a reagent capable of reacting with at least some of the organic impurities, with the exception of a reaction with elemental chlorine.</p> |
