Abstract
La présente invention concerne un procédé de déhydrofluoration comprenant les étapes de : a) fourniture d'un courant A comprenant au moins un composé hydrocarbure de départ comprenant de 2 à 6 atomes de carbone, au moins un atome d'hydrogène et au moins un atome de fluor ; b) dans un réacteur, mise en contact dudit courant A en présence ou non d'un catalyseur de déhydrofluoration pour produire un courant B comprenant un composé hydrocarbure final comprenant de 2 à 6 atomes de carbone et un nombre d'atomes de fluor inférieur à celui dudit hydrocarbure de départ ; caractérisé en ce que la conductivité électrique dudit courant A fourni à l'étape a) est inférieure à 15 mS/cm.The present invention relates to a dehydrofluorination process comprising the steps of: a) supplying a stream A comprising at least one starting hydrocarbon compound comprising from 2 to 6 carbon atoms, at least one hydrogen atom and at least one atom fluorine; b) in a reactor, bringing said stream A into contact with or without a dehydrofluorination catalyst to produce a stream B comprising a final hydrocarbon compound comprising from 2 to 6 carbon atoms and a number of fluorine atoms less than that of said starting hydrocarbon; characterized in that the electrical conductivity of said current A supplied in step a) is less than 15 mS / cm.
