Description

  

      Verfahren    zur Darstellung eines     Aminoarylsulfonsäurederivates.       Gegenstand des vorliegenden Patentes ist  ein Verfahren zur Darstellung eines     Amino-          arylsulfonsäurederivates,dadurch    gekennzeich  net; dass man 2-Amino-4,4'-dichlor-1,1'-di-         phenyläther-2'-sulfonsäure    mit     Bernsteinsäure-          dichlorid    umsetzt.  



  Die neue Verbindung der Formel  
EMI0001.0008     
    bildet als     Natriumsalz    ein helles, in Wasser  lösliches Pulver und eignet sich als Motten  schutzmittel.  



  <I>Beispiel:</I>  35,6 Teile     2-Amino-4,4'-dichlor-1,1'-di-          phenyläther-2'-sulfonsäure    werden in<B>150</B> Vol.-    Teilen wasserfreiem     Pyridin    gelöst und unter  starkem Rühren bei 5-10   C 7,75 Teile       Bernsteinsäuredichlorid    in kleinen Portionen  zugegeben. Die Temperatur wird während  einer Stunde auf<B>5-10'</B> gehalten, dann eine  weitere Stunde auf 20-25   erwärmt und  hierauf mit Wasserdampf das     Pyridin    abge-      blasen. Die zurückbleibende Lösung wird  nun langsam mit Sole versetzt, wobei das  Kondensationsprodukt schön kristallin aus  fällt. Es wird     abgesaugt,    mit wenig Salz  wasser nachgewaschen und getrocknet.



      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 thereby; that 2-amino-4,4'-dichloro-1,1'-diphenyl ether-2'-sulfonic acid is reacted with succinic acid dichloride.



  The new compound of the formula
EMI0001.0008
    The sodium salt forms a light-colored powder that is soluble in water and is suitable as a moth repellent.



  <I> Example: </I> 35.6 parts of 2-amino-4,4'-dichloro-1,1'-diphenyl ether-2'-sulfonic acid are in <B> 150 </B> vol. Parts of anhydrous pyridine dissolved and 7.75 parts of succinic acid dichloride were added in small portions at 5-10 ° C. with vigorous stirring. The temperature is kept at 5-10 'for one hour, then heated to 20-25 for a further hour and the pyridine is then blown off with steam. The remaining solution is then slowly mixed with brine, the condensation product precipitating out in a nicely crystalline form. It is filtered off with suction, washed with a little salt water and dried.
