Abstract

La présente invention concerne un procédé de préparation de 1,1,1,2,3,3,3-heptafluoropropane (HFC 227ea) consistant à faire réagir un hexafluoropropane (HFP) avec un fluorure d'hydrogène. Ledit procédé consiste: à charger le mélange réactionnel dans un séparateur en phase liquide; à permettre à une phase riche en HFC 227ea de se séparer par effet de gravité; à recycler la phase riche en fluorure d'hydrogène; à charger la phase riche en HFC 227ea dans une colonne de distillation; à récupérer séparément le HFC 227ea et un mélange riche en fluorure d'hydrogène contenus dans la colonne de distillation; puis à recycler le mélange riche en fluorure d'hydrogène dans le réacteur.
