Abstract

La présente invention concerne un procédé de purification du 2-chloro-1, 1,1,2-tétrafluoropropane (HCFC-244bb) à partir d'une première composition comprenant 2-chloro-1,1,1,2-tétrafluoropropane et 2-chloro-3,3,3-trifluoropropène, ledit procédé comprenant les étapes de : a) mise en contact de ladite première composition avec au moins un agent d'extraction organique pour former une seconde composition ; b) distillation extractive de ladite seconde composition pour former : i) une troisième composition comprenant ledit agent d'extraction organique et 2-chloro-3,3,3-trifluoropropène, ii) un courant comprenant le 2-chloro -1,1,1,2-tétrafluoropropane ; c) récupération et séparation de ladite troisième composition pour former un courant comprenant ledit agent d'extraction organique et un courant comprenant 2-chloro-3,3,3-trifluoropropène.
