Description

  

  Verfahren zur Darstellung eines     Aminoarylsulfonsäurederivates.       Gegenstand des vorliegenden Patentes ist  ein Verfahren zur Darstellung eines     Amino-          arylsulfonsäurederivates,    dadurch gekenn  zeichnet, dass man     2-Amino-4,4'-dicblor-1,1'-          diphenyläther-2'-sulfonsäure    mit Chloressig  säure-3,4-dichlorariilid umsetzt.  



  Die neue Verbindung der wahrscheinlichen  Formel  
EMI0001.0006     
    bildet als     Natriumsalz    ein helles, in heissem  Wasser lösliches Pulver und eignet sich als  Mottenschutzmittel.  



  <I>Beispiel:</I>  20 Teile     2-Amino-4,4'-dichlor-1,1'-diphenyl-          äther-2'-sulfonsäure    werden mit 12 Teilen         Chloressigsäure-3,4-dichloranilid    in 100     Vol.-          Teilen    heissem Alkohol gelöst und mit 5 Tei  len     calc.    Soda versetzt. Hierauf wird unter  Rühren<B>15</B> Stunden unter     Rückfluss    gekocht,  dann mit 300 Teilen Wasser verdünnt und  das ausgeschiedene Produkt     abgenutscht.    Es  wird in heissem Wasser aufgenommen, von  wenig Unlöslichem heiss     abfiltriert    und das  Filtrat gekühlt.

   Dabei scheidet sich das Kon  densationsprodukt aus; es wird im Vakuum  getrocknet und bildet dann ein helles, in  heissem Wasser lösliches Pulver.



  Process for the preparation of an aminoarylsulfonic acid derivative. The subject of the present patent is a process for the preparation of an amino arylsulfonic acid derivative, characterized in that 2-amino-4,4'-dicbloro-1,1'-diphenyl ether-2'-sulfonic acid with chloroacetic acid-3,4- dichlorariilid converts.



  The new compound of the probable formula
EMI0001.0006
    As a sodium salt, it forms a light-colored powder that is soluble in hot water and is suitable as a moth repellent.



  <I> Example: </I> 20 parts of 2-amino-4,4'-dichloro-1,1'-diphenyl-ether-2'-sulfonic acid are mixed with 12 parts of chloroacetic acid-3,4-dichloroanilide in 100 vol. - Dissolved parts of hot alcohol and calcined with 5 parts. Soda added. The mixture is then refluxed for <B> 15 </B> hours with stirring, then diluted with 300 parts of water and the product which has separated out is filtered off with suction. It is taken up in hot water, little insoluble matter is filtered off while hot and the filtrate is cooled.

   The condensation product separates out; it is dried in a vacuum and then forms a light-colored powder that is soluble in hot water.
