Abstract: The invention relates to the continuous preparation of heptafluoropropane by conversion of hexafluoropropene with HF in the presence of a liquid hydrofluoride of an organonitrogen base corresponding to the formula [B.times.nHF], in which B represents an organonitrogen base and n represents an integer or a fraction.ltoreq.4, during which HF, hexafluoropropene and the hydrofluoride are converted in a first zone at an elevated pressure p.sub.1, the resulting heptafluoropropane is then evaporated off and isolated from the liquid reaction mixture, in a second zone under a pressure p.sub.2 <p.sub.1, and the remaining liquid reaction mixture is then transferred back into the first zone.

Abstract: The invention relates to a process for the preparation of acesulfam salts by reaction of salts of amidosulfonic acid with diketene to give a salt of acetoacetamidosulfonic acid (I), ring closure by the action of at least about an equivalent amount of SO.sub.3, at least this ring closure reaction being carried out in the presence of a halogenated, aliphatic hydrocarbon as an inert solvent, treatment of the cyclization product with water and conversion of the resulting acesulfam-H (II) into the form of a non-toxic salt, which comprises, in the work-up by distillation of the resulting crude solvent, after removal of water and low-boilers and recovery of solvent sufficiently pure for reuse in the preparation of compounds (I) and/or (II), directly returning :he remaining, solvent-containing distillation residue, without further purification, into the system downstream of the reaction vessel for carrying out the ring closure reaction.
