Description

Verfahren zur Herstellung von Disulfimiden bzw. deren Salzen Gegenstand des Patents 757 603 ist ein Verfahren zur Herstellung von Disul,fimiden bzw. deren Salzen, die nach der allgemeinen Formel R-;S 02-N(Kat)-S 02-R' zusammengesetzt sind, in welcher wenigstens einer der beiden ResteR und R' einen wenigstens eine lipophile Gruppe und gegebenenfalls Heteroatome oder Heteroatomgruppen enthaltenden organischen Rest bedeutet, während der andere Rest ein beliebiger, gegebenenfalls durch Heteroatome oder Heteroatomgruppen unterbrochener Kohlenwasserstoffrest sein kann und K.at ein beliebiges Kation bedeutet, das zur Bildung wasserlöslicher ',Salze befähigt ist. ,Das Verfahren besteht darin, daß man Sulfonsäurehalogeni-de der allgemeinen Formel R@S02 Hal mit Metallverbindungen von Sulfonsäureamiden (der allgemeinen Formel R',S 02-N H2 kondensiert, wobei R und R' die oben angegebene Bedeutung haben, .und .die erhaltenen Kondensationsprodukte gegebenenfalls mit anorganischen oder organischen Basen in wasserlösliche Salze überführt.Process for the production of disulfimides or their salts The subject of patent 757 603 is a process for the production of disulfimides or their salts, which are composed according to the general formula R-; S 02-N (Kat) -S 02-R ' are, in which at least one of the two radicals R and R 'is an organic radical containing at least one lipophilic group and optionally heteroatoms or heteroatom groups, while the other radical can be any hydrocarbon radical, optionally interrupted by heteroatoms or heteroatom groups, and K.at is any cation means that it is capable of forming water-soluble salts. The process consists in condensing sulfonic acid halides of the general formula R @ S02 Hal with metal compounds of sulfonic acid amides (of the general formula R ', S 02-N H2, where R and R' have the meanings given above, and. the condensation products obtained are converted into water-soluble salts, if appropriate with inorganic or organic bases.

Es wurde nun gefunden, daß man obiges Verfahren in den (Fällen erheblich vereinfachen kann, in welchen R gleich R' ist. In diesen Fällen ist es nämlich nicht erforderlich, .die "Sulfonsäureamide R-S 02-N H2 gesondert herzustellen und dann mit den Su'lfonsäumhalogeniden R-S 02 Hal umzusetzen; man kann vielmehr letztere unmittelbar in Gegenwart alkalisch wirkender Mittel auf Ammoniak oder beliebige Ammoniumsalze einwirken lassen; wobei man 2 NZol Sulfonsäurehalogen.id auf z Mol Ammoniak bzw. die äquivalente Menge Ammoniumsalz anwendet. Offenbar bildet sich hierbei als Zwischenprodukt das betreffendeSulfonsäureamid, das dann mit einem zweiten Mol Sulfonsäurehalogenid unter Bildung des Disulfimids weiter reagiert. Beispiel 53,5 Gewichtsteile,Salmiak werden in goo Teilen Wasser gelöst; die Lösung wird auf o bis 5° abgekühlt, und es werden zoo Raumteile einer 3o°/aigen Natronlauge hinzugefügt. In die Mischung rührt man unter Eiskühlung q.26 Gewichtsteile n-Octansulfochlorid ein. Nach '/2stündigem Nachrühren bei o bis 5° erhöht man die Temperatur auf 2o° und beginnt mit der Zugabe von Natronlauge, sobald die phenolphthalein-alkalische Reaktion zu verschwinden droht. Die Mischung verwandelt sich allmählich in einen dicken weißen Brei. i4lan erwärmt langsam im Laufe einiger Stunden auf go°, indem man ständig durch vorsichtige Zugabe von Natronlauge eine schwach phenolphthalein-alkalische Reaktion aufrechterhält. Sobald dieselbe etwa r rStunde bei 9o bis 95° bestehen bleibt, wird mit Salzsäure lackmusneutral gestellt, auf Raumtemperatur abgekühlt und das breiförmig ,ausgeschiedene Natriumsalz des Di-n-octandisulfimids abgesaugt und bei ioo° getrocknet. Weißes Pulver, in warmem Wasser leicht unter starkem !Schäumen löslich, auch aus rA11eohol umkristallisierbar.It has now been found that the above procedure can be used in the (cases considerably can simplify in which R equals R '. In these cases it is not necessary to prepare the "sulfonic acid amides R-S 02-N H2 separately and then with to implement the Su'lfonsäumhalogeniden R-S 02 Hal; one can rather the latter immediately in the presence of alkaline agents for ammonia or any other Let ammonium salts take effect; where 2 NZol sulfonic acid halide per z mol Ammonia or the equivalent amount of ammonium salt is used. Apparently it is forming here as an intermediate product the sulfonic acid amide in question, which is then mixed with a second Mol sulfonic acid halide reacts further to form the disulfimide. example 53.5 parts by weight of ammonia are dissolved in 100 parts of water; the solution will be on Cooled to 5 °, and zoo parts of a 30% sodium hydroxide solution are added. 26 parts by weight of n-octanesulfonyl chloride are stirred into the mixture while cooling with ice a. After stirring for 1/2 hour at 0 to 5 °, the temperature is increased to 20 ° and starts adding caustic soda as soon as the phenolphthalein is alkaline Reaction threatens to disappear. The mixture gradually turns into one thick white porridge. i4lan slowly warms up to go ° over the course of a few hours by one constantly a weakly phenolphthalein-alkaline by carefully adding caustic soda Sustains response. As soon as they exist for about r r hour at 9o to 95 ° remains, is made litmus neutral with hydrochloric acid, cooled to room temperature and sucked off the pulpy, precipitated sodium salt of di-n-octanedisulfimide and dried at 100 °. White powder, in warm water slightly with strong foaming soluble, can also be recrystallized from rAl alcohol.
