Title (EN) PROCESS FOR THE PREPARATION OF FLUORINATED CIS-ALKENE
(FR) PROCÉDÉ DE PRÉPARATION D'UN CIS-ALCÈNE FLUORÉS
Abstract: front page image
(EN)Disclosed is a process for the preparation of fluorine-containing olefins comprising contacting a chlorofluoroalkane with hydrogen in the presence of a catalyst at a temperature sufficient to cause replacement of the chlorine substituents of the chlorofluoroalkane with hydrogen to produce a fluorine-containing olefin. Also disclosed are catalyst compositions for the hydrodechlorination of chlorofluoroalkanes comprising copper metal deposited on a support, and comprising palladium deposited on calcium fluoride, poisoned with lead and reducing the in the presence or absence of a dehydrochlorination catalyst under conditions effective to form a product stream comprising cis-1,1,1,4,4,4-hexafluoro-2-butene (HFO-1336).
(FR)L'invention concerne un procédé de préparation d'oléfines contenant du fluor comprenant la mise en contact d'un chlorofluoroalcane avec de l'hydrogène en présence d'un catalyseur à une température suffisante pour provoquer un remplacement des substituants chlore du chlorofluoroalcane par de l'hydrogène afin de produire une oléfine contenant du fluor. L'invention concerne également des compositions de catalyseur pour l'hydrodéchloration de chlorofluoroalcanes comprenant du cuivre métallique déposé sur un support et comprenant du palladium déposé sur du fluorure de calcium, empoisonné par du plomb et la réduction en présence ou en l'absence d'un catalyseur de déhydrochloration dans des conditions efficaces pour former un courant de produit comprenant du cis-1,1,1,4,4,4-hexafluoro-2-butène (HFO-1336).
