PROCESS FOR THE ADDITION OF HF TO HALOGENATED ALKENES

摘要

Process for the addition of HF to halogenated alkenes The invention relates to a process for the addition of HF to halogenated alkenes by reacting these with at least one hydrofluoride of the formula [B.cndot.n HF], in which B is an organic nitrogen base and n is as integer or fraction .ltoreq. 4, it being intended that the reaction of perfluoroiso- butene CF2=C(CF3)2 is excluded.
