Description

       

  verfahren     zur    Herstellung eines aromatischen     Acylsulfonamides.       Gegenstand vorliegenden Patentes ist ein       Verfahren    zur Herstellung eines aromati  schen Asylsulfonamides. Das Verfahren ist  dadurch gekennzeichnet,     da.ss    man eine     Ver-          V)indung    der Formel  
EMI0001.0007     
    auf eine Verbindung der Formel  
EMI0001.0008     
    worin X und Y     zwei    reaktionsfähige, bei der  Reaktion mit Ausnahme einer in einem von  ihnen enthaltenen     NH-Gruppe    sich abspal  tende Reste bedeuten, einwirken lässt.  



  Die entstandene neue Verbindung, das       N-(Cinnamoyl)-3,5-dichlor-benzolsulfonamid,     schmilzt bei 160  und soll als Desinfektions  mittel, z. B. für Gebrauchsgegenstände, Ver  wendung finden.  



       Beispiel   <I>1:</I>  Teile     3,5-Dichlor-benzolsulfonamid     werden in 100 Teilen Nitrobenzol suspen  diert und mit 19 Teilen Aluminiumchlorid       und    16,6 Teile     Zimtsäurechlorid    versetzt.  Das Gemisch wird 2 Stunden auf 50  er  wärmt und hierauf das Lösungsmittel mit  Wasserdampf     abdestilliert.    Der Rückstand  wird in     Sodalösung    aufgenommen, mit Tier  kohle behandelt und filtriert. Aus dem     El-          trat    wird das N-(Cinnamoyl)-3,5-dichlor-         benzolsulfonamid    mit Essigsäure ausgefällt  und durch     Umkristallisieren    aus Alkohol  gereinigt.

    



  Statt     unter    Zuhilfenahme eines     fionden-          sationsmittels    kann die Reaktion auch in  Gegenwart eines säurebindenden Mittels, wie  z. B. von     Pyridin    oder     Dimethylanilin,    oder  in Gegenwart eines     Katalysators,        wie    z. B.  von Kupferpulver,     ausgeführt    werden.  



  An Stelle eines     Halogenides    kann auch  die freie Zimtsäure in Gegenwart eines Kon  densationsmittels, wie     Phosphorpentogyd     oder     Phosphorpentachlorid,    verwendet wer  den.  



       Beispiel   <I>2:</I>  24,8 Teile     Zimtsäureamid    werden in 200  Teilen absolutem     Xylol    gelöst.. Dann fügt  man 8 Teile     Natriumamid    hinzu und er  wärmt bis zum Aufhören der Ammoniak  entwicklung.

   Nach dem     Abkühlen    gibt man  49,1 Teile     3,5-Dichlor-benzolsulfochlorid    in  100 Teilen     Xylol    zu und erhitzt mehrere  Stunden unter     Rückfluss.    Nach beendeter Re  aktion wird das     Xylol    im Vakuum     abdestil-          liert.    Der Rückstand wird in     Bicarbonat-          lösung    aufgenommen, mit Tierkohle behan  delt, filtriert und durch Ansäuern ausgefällt.

    Das     N-(Cinnamoyl)-3,5-,dichlor-benzolsulfon-          amid    wird aus verdünntem Alkohol     umkri-          stallisiert    und so völlig rein erhalten.



  process for the production of an aromatic acylsulfonamide. The present patent is a process for the preparation of an aromatic rule asylsulfonamide. The process is characterized in that one uses the formula
EMI0001.0007
    to a compound of the formula
EMI0001.0008
    wherein X and Y mean two reactive radicals which split off during the reaction with the exception of an NH group contained in one of them.



  The resulting new compound, the N- (cinnamoyl) -3,5-dichloro-benzenesulfonamide, melts at 160 and should be used as a disinfectant, eg. B. for everyday objects, Ver use.



       Example 1: Parts of 3,5-dichlorobenzenesulfonamide are suspended in 100 parts of nitrobenzene, and 19 parts of aluminum chloride and 16.6 parts of cinnamic acid chloride are added. The mixture is heated to 50 for 2 hours and the solvent is then distilled off with steam. The residue is taken up in soda solution, treated with animal charcoal and filtered. The N- (cinnamoyl) -3,5-dichlorobenzenesulphonamide is precipitated from the eluate with acetic acid and purified by recrystallization from alcohol.

    



  Instead of using a fioning agent, the reaction can also be carried out in the presence of an acid-binding agent, such as. B. of pyridine or dimethylaniline, or in the presence of a catalyst, such as. B. of copper powder.



  Instead of a halide, the free cinnamic acid can also be used in the presence of a condensation agent such as phosphorus pentogide or phosphorus pentachloride.



       Example <I> 2: </I> 24.8 parts of cinnamic acid amide are dissolved in 200 parts of absolute xylene. 8 parts of sodium amide are then added and it is warmed until the evolution of ammonia ceases.

   After cooling, 49.1 parts of 3,5-dichlorobenzenesulfochloride in 100 parts of xylene are added and the mixture is refluxed for several hours. After the reaction has ended, the xylene is distilled off in vacuo. The residue is taken up in bicarbonate solution, treated with animal charcoal, filtered and precipitated by acidification.

    The N- (cinnamoyl) -3,5-, dichlorobenzenesulfonamide is recrystallized from dilute alcohol and thus obtained completely pure.
