Abstract: front page image
(EN)A mixture comprising at least 1,1,1,3,3-pentafluoropropane and 1,1,1-trifluoro-3-chloro-2-propene is subjected to a distillation step to obtain a distillate comprising an azeotropic composition consisting substantially of 1,1,1,3,3-pentafluoropropane and 1,1,1-trifluoro-3-chloro-2-propene. From the distillate is obtained a bottom comprising 1,1,1,3,3-pentafluoropropane or 1,1,1-trifluoro-3-chloro-2-propene which each has been separated from the other and purified.
(FR)La présente invention concerne un mélange renfermant au moins 1,1,1,3,3-pentafluoropropane et de 1,1,1-trifluoro-3-chloro-2-propène soumit à une étape de distillation pour obtenir un distillat à base d'une composition azéotrope comprenant sensiblement 1,1,1,3,3-pentafluoropropane et 1,1,1-trifluoro-3-chloro-2-propène. On obtient à partir du distillat une base comprenant 1,1,1,3,3-pentafluoropropane ou 1,1,1-trifluoro-3-chloro-2propène, séparés les uns des autres puis purifiés.
