Title (EN) PROCESS FOR PREPARATION OF HYDROFLUOROALKENES BY SELECTIVE CATALYTIC CONSECUTIVE HYDRODEFLUORINATION
(FR) PROCÉDÉ DE PRÉPARATION D'HYDROFLUOROALCÈNES PAR HYDROFLUORATION CONSÉCUTIVE CATALYTIQUE SÉLECTIVE
Abstract:
(EN) The present application provides a hydrodefluorination process for the preparation of hydrofluoroalkenes by catalyzed substitution of one or more F atoms of a C2-C30 fluoroalkene, or a C2-C10 fluoroalkene, with one or more H atoms using a hydride source, such as a silane, and copper catalyst. During this process at least one C-F bond in the fluoroakene is converted to a C-H bond. The process is useful in the manufacture of hydrofluoroalkenes, such as hydrofluoroalkenes employed as, for example, refrigerants and blowers. Also provided are precatalyst compositions for performing the process, and formulations manufactured from hydrofluoroalkenes produced using the process.
(FR) La présente invention concerne un procédé d'hydrodéfluoration pour la préparation d'hydrofluoroalcènes par substitution catalysée d'un ou plusieurs atomes F d'un fluoroalcène en C2-C30, ou un fluoroalcène en C2-C10, avec un ou plusieurs atomes de H à l'aide d'une source d'hydrure, telle qu'un silane, et un catalyseur de cuivre. Pendant ce procédé, au moins une liaison C-F dans le fluoroakène est convertie en une liaison C-H. Le procédé est utile dans la fabrication d'hydrofluoroalcènes, tels que des hydrofluoroalcènes utilisés en tant que réfrigérants et ventilateurs, par exemple. L'invention concerne également des compositions de précatalyseur pour la mise en oeuvre du procédé, et des formulations fabriquées à partir d'hydrofluoroalcènes produits à l'aide du procédé.
