Method for separating a mixture comprising at least a hydrofluoroalkane and hydrogen fluoride, and process for preparing a hydrofluoroalkane |
| abstract |
The invention concerns a method for separating a mixture comprising at least a hydrofluoroalkane and hydrogen fluoride, which consists in reacting a hydrofluoroalkane/hydrogen fluoride mixture with at least a chlorinated or chlorofluorinated precursor of hydrofluoroalkane. The invention also concerns a method for preparing a hydrofluoroalkane comprising such separation, combined with a catalytic reaction step. The invention further concerns azeotropic compositions. |
