Abstract

L'invention concerne une préparation d'un composé organique contenant du fluor, consistant à faire réagir un haloalcène avec du fluorure d'hydrogène, dans laquelle à la fois le composé organique contenant du fluor et l'haloalcène forment séparément des azéotropes avec du fluorure d'hydrogène, et dans laquelle l'azéotrope haloalcène/fluorure d'hydrogène est plus volatile que l'azéotrope composé organique contenant du fluor/fluorure d'hydrogène.
