Title
(EN) PROCESS FOR MAKING HYDROHALOCARBONS AND SELECTED COMPOUND
(FR) PROCÉDÉ POUR PRODUIRE DES HYDROCARBURES HALOGÉNÉS ET COMPOSÉ SÉLECTIONNÉ
Abstract
(EN)
A process is disclosed for producing addition compound CHCI2CHXCCIYR, wherein X and Y are each independently selected from the group consisting of H, F, CI and Br, and R = H or a perhalogenated alkyl group. The process involves a liquid phase reaction of CHCI3 with CHX=CYR in the presence of an addition catalyst. New compound disclosed is CHCI2CH2CHCICF3. It is useful as an intermediate for producing hydrofluorocarbons and hydrofluoroolefins.
(FR)
La présente invention concerne un procédé pour produire un composé d'addition CHCl2CHXCClYR, dans lequel X et Y sont chacun indépendamment choisis dans le groupe constitué de H, F, Cl et Br, et R = H ou un groupe alkyle perhalogéné. Le procédé met en œuvre une réaction en phase liquide de CHCl3 avec CHX=CYR en présence d'un catalyseur d'addition. Le nouveau composé décrit est CHCl2CH2CHClCF3. Il est utile en tant qu'intermédiaire pour produire des hydrofluorocarbones et des hydrofluorooléfines.
