Process of separating/purifying pentafluoropropane

   
   

There is provided an azeotropic mixture having 1,1,1,3,3-pentafluoropropane and hydrogen fluoride. Further, there is provided a process of separating/purifying R-245fa and/or HF from a mixture of R-245fa and HF wherein the mixture of 1,1,1,3,3-pentafluoropropane and hydrogen fluoride is subjected to a distillation step so that a distillate is obtained which has the azeotropic mixture of 1,1,1,3,3-pentafluoropropane and hydrogen fluoride, and a bottom product is obtained which has separated/purified 1,1,1,3,3-pentafluoropropane or hydrogen fluoride.

On fournit un mélange azéotropique ayant 1,1,1,3,3-pentafluoropropane et fluorure d'hydrogène. Plus loin, on fournit un processus de separating/purifying R-245fa et/ou à haute fréquence d'un mélange de R-245fa et à haute fréquence où le mélange de 1,1,1,3,3-pentafluoropropane et de fluorure d'hydrogène est soumis à une étape de distillation de sorte qu'un distillat soit obtenu qui a le mélange azéotropique de 1,1,1,3,3-pentafluoropropane et de fluorure d'hydrogène, et on obtient un produit inférieur qui a separated/purified 1,1,1,3,3-pentafluoropropane ou fluorure d'hydrogène.
