Abstract
Halohydrocarbons comprising at least 3 carbon atoms are obtained by batchwise reaction between a haloalkane and an olefin in the presence of a catalyst and a co-catalyst. The addition of at least some of the co-catalyst is carried out gradually. At least some of the co-catalyst is recovered with a view to its re-use.
