Description
Verfahren zur Herstellung von Sulfamiden Amide aromatischer Sulfonsäuren hat man bisher im wesentlichen durch Umsetzung der Sulfochloride mit Ammoniak gewonnen. Es wurde nun gefunden, daß man die Sulfamidgruppe in Kohlenwasserstoffe, die mindestens ein aromatisches Ringsystem enthalten, in direkter Weise dadurch einführen kann, daß man diese Kohlenwasserstoffe mit Sulfaminsäurechlorid in Gegenwart Friedel-Craftss.cher Katalysatoren. zur Umsetzung bringt und das Reaktionsgemisch nach erfolgter Umsetzung mit Wasser zersetzt.Process for the preparation of sulfamides Amides of aromatic sulfonic acids has so far been obtained essentially by reacting the sulfochlorides with ammonia. It has now been found that the sulfamide group in hydrocarbons that at least contain an aromatic ring system, can thereby introduce in a direct manner, that these hydrocarbons with sulfamic acid chloride in the presence of Friedel-Craftss.cher Catalysts. brings to implementation and the reaction mixture after the implementation decomposed with water.
Sulfaminsäurechlorid reagiert mit Kohlenwasserstoffen, die mindestens ein. aromatisches Ringsystem enthalten, bei Zugabe von Friedel-Crafts-Katalysatoren unter Chlorwasserstoffabspaltung, wobei der Sulfamidrest unmittelbar an das aromatische Ringsystem tritt. Beispielsweise erhält man ausgehend von Benzol im Sinne der Gleichung Benzolsulfamid. Als aromatische Kohlenwasserstoffe kommen Benzol, Toluol, Cumol, Xylol, Dodeey.lbenizol', Naphthalin, Anthrazen, Cyclohexylbenzol, Dip'henyl oder einfache Substitutionsprodukte dieser Kohlenwasserstoffe, beispielsweise Ch.lorbeuzöl, Fduorbenizol u. a., in Betracht.Sulfamic acid chloride reacts with hydrocarbons containing at least one. contain aromatic ring system, upon addition of Friedel-Crafts catalysts with elimination of hydrogen chloride, the sulfamide radical coming directly to the aromatic ring system. For example, starting from benzene in the sense of the equation Benzenesulfamide. Suitable aromatic hydrocarbons are benzene, toluene, cumene, xylene, dodecylbenizol ', naphthalene, anthracene, cyclohexylbenzene, diphenyl or simple substitution products of these hydrocarbons, for example chlorobenz oil, fluorobenzene and others.
Sulfaminsäurechlorid kann beispielsweise nach dem Verfahren des Patents 937 645 hergestellt werden. Als Friedel-Craftssche Katalysatoren verwendet man vornehmlich Aluminiumchlorid, Eisenchlorid oder einfache Komplexverbindungen, beispielsweise NatTium-Aluminiwmchlorid.Sulfamic acid chloride can, for example, according to the method of the patent 937 645. The Friedel-Crafts catalysts are mainly used Aluminum chloride, iron chloride or simple complex compounds, for example Sodium aluminum chloride.
Man führt die Reaktion in der Weise aus, daß man in die Mischung aus Sulfaminsäurechlorid und dem aromatischen Kohlenwasserstoff, zweckmäßig unter Rühren und Kühlung, Aluminiumchlorid einträgt. Man kann ebensogut auch eine Mischung aus Aluminiumchlorid und Kohlenwasserstoff vorlegen und dann das Sulfaminsäurechlorid eintragen. Man rührt eine Zeitlang bis zur beendeten Reaktion: bei etwas erhöhter Temperatur nach und zersetzt dann mit Eis. Man entfernt den überschüssigen Kohlenwasserstoff, beispielsweise durch Destillation mit Wasserdampf, und trennt das aus der wäßrigen Lösung abgeschiedene Sulfamid ab.The reaction is carried out in such a way that one in the mixture from Sulfamic acid chloride and the aromatic hydrocarbon, advantageously with stirring and cooling, aluminum chloride enters. You can just as easily mix it up Submit aluminum chloride and hydrocarbon and then the sulfamic acid chloride enter. One stirs for a while until the reaction has ended: with a slightly increased reaction Temperature and then decomposes with ice. Remove the excess hydrocarbon, for example by distillation with steam, and separates it from the aqueous Solution deposited sulfamide.
Sofern die als Ausgangsmaterial verwendeten Kohlenwasserstoffe fest sind, kann man auch bei erhöhter Temperatur arbeiten, um die Reaktion in der flüssigen Phase durchführen zu können. Man kann jedoch auch bei der Friedel-Crafts-Reaktion gebräuchliche Lösungsmittel, beispielsweise Tetrachlorkohlenstoff oder Nitrobenzol, verwenden.Provided the hydrocarbons used as the starting material are solid are, you can also work at elevated temperature to make the reaction in the liquid Phase to be able to carry out. However, one can also use the Friedel-Crafts reaction Common solvents, for example carbon tetrachloride or nitrobenzene, use.
Beispiel 1 Zu einer Lösung von 116 Gewichtsteilen Sulfaminsäurechlorid in 800 Gewichtsteilen Benzol setzt man unter Rühren und Kühlung 140 Gewichtsteile Aluminiumchlorid. zu, das unter Bildung einer benzollöslichen Anlagerungsverbindung in Lösung geht. Beim Erwärmen auf 40° erfolgt Chlorwasserstoffentwicklung. Bis zur Beendigung der Umsetzung rührt man noch 1/z Stunde bei 50°. Nach dem Erkalten gießt man die braune Lösung auf Eis und treibt das Benzol mit Wasserdampf ab. Die nunmehr farblose wäßrige Lösung scheidet beim Erkalten 120 bis 130 Gewichtsteile Benzolsulfamid vom Schmelzpunkt 150 bis 151° in Form farbloser Blättchen aus, die man durch Absaugen isoliert.Example 1 To a solution of 116 parts by weight of sulfamic acid chloride 140 parts by weight are placed in 800 parts by weight of benzene with stirring and cooling Aluminum chloride. to that with the formation of a benzene-soluble addition compound goes into solution. When heated to 40 °, hydrogen chloride is generated. To When the reaction is complete, the mixture is stirred at 50 ° for a further 1/2 hour. Pour after cooling the brown solution is placed on ice and the benzene is driven off with steam. The now colorless aqueous solution separates 120 to 130 parts by weight of benzenesulfamide on cooling from a melting point of 150 to 151 ° in the form of colorless flakes, which can be removed by suction isolated.
Beispiel 2 In der im Beispiel l beschriebenen Weise werden 116 Gewichtsteile Sulfaminsäurechlorid mit 800 Gewichtsteilen Toluol in Gegenwart von 140 Gewichtsteilen Aluminiumchlorid umgesetzt. Es werden etwa 130 bis 140 Gewichtsteile eines Gemisches der isomeren Toluolsulfamide erhalten, das unscharf zwischen 120 bis 130° schmilzt. Durch fraktioniertes Fällen der natronalkalischen Lösung des Rohsulfamids mit verdünnter Salzsäure und Umkristallisderen aus schwach verdünntem Methanol erhält man, daraus 25 bis 30 Gewichtsteile o-Toluo,l,sulfamid vom Schmelzpunkt 153 bis 154°. Der Rest stellt im wesentlichen p-Toluolsüfamid dar.Example 2 In the manner described in Example 1 there are 116 parts by weight Sulfamic acid chloride with 800 parts by weight of toluene in the presence of 140 parts by weight Aluminum chloride implemented. There will be about 130 to 140 parts by weight of a mixture the isomeric toluenesulfamide obtained, which melts fuzzy between 120 and 130 °. By fractional precipitation of the sodium-alkaline solution of the crude sulfamide with dilute Hydrochloric acid and recrystallized products from weakly diluted methanol are obtained therefrom 25 to 30 parts by weight of o-toluo, l, sulfamide from melting point 153 up to 154 °. The remainder is essentially p-toluene sulfamide.
