METHOD FOR OBTAINING HALOGENATED HYDROCARBONS IN THE PRESENCE OF A CO-CATALYST

摘要

The invention concerns a method for obtaining halogenated hydrocarbons comprising at least 3 carbon atoms by discontinuous reaction of a haloalkane with an olefin in the presence of a catalyst and a co-catalyst and by gradually adding at least part of the co-catalyst. At least part of the co-catalyst is recovered for re-use.
