Title
(EN) METHOD FOR MAKING ALKANESULPHONYL CHLORIDES
(FR) PROCEDE DE FABRICATION DE CHLORURES D'ALCANESULFONYLE
Abstract
(EN)
The invention concerns a method for making alkanesulphonyl chloride RCH2-SO2CI by oxidising chlorinolysis of the corresponding mercaptan RCH2-SH, mercaptan and water being introduced in the reaction mixture in the form of a water dispersion in mercaptan. Said process results both in very high quality alkanesulphonyl chloride and commercial grade hydrochloric acid.
(FR)
Dans le procédé selon l'invention pour la fabrication d'un chlorure d'alcane-sulfonyle RCH2-SO2CI par chlorolyse oxydante du mercaptan RCH2-SH correspondant, le mercaptan et de l'eau sont introuduits dans le mélange réactionnel sous forme d'une dispersion d'eau dans le mercaptan. Ceci permet d'obtenir à la fois un chlorure d'alcanesulfonyle de très bonne qualité et un acide chlorhydrique de qualité commerciale.
