Description

  

      Verfahren    zur Herstellung einer wasserlöslichen     Diazoamidoverbindung.       Gegenstand des vorliegenden Patentes  ist ein Verfahren<I>zur</I> Herstellung einer was  serlöslichen     Diazoamidoverbindung.    Es ist  dadurch gekennzeichnet, dass man     Prolin    auf  dianotiertes     1,4-1)iätlioxy-2-aniido-5-berizoyl-          amidobenzol    in     C-xegeriwart    eines säurebin  denden Mittels einwirken lässt.  



  <I>Beispiel:</I>  In eine     sodaalkalische    Lösung aus 9     gi-          Prolin    und 25     gr    Soda lässt man bei<B>15'</B>  eine     Diazolösung    aus 22     gr        1,4-Diäthoxy-2-          amido-5-benzoylamidobenzol    laufen.     DieKupp-          lung    ist bald beendet. Die     Diazoamidoverbin-          dung,    die sich zum Teil von selbst abscheidet,  wird durch Zusatz von Kochsalz ausgefällt.

      Sie stellt getrocknet ein schwach angefärbtes,  wasserlösliches Pulver dar und ist ein wert  volles Produkt für     Färbereizwecke.  



      Process for producing a water-soluble diazoamido compound. The subject of the present patent is a process for the preparation of a water-soluble diazoamido compound. It is characterized in that proline is allowed to act on dianotated 1,4-1) iätlioxy-2-aniido-5-berizoyl-amidobenzene in the presence of an acid-binding agent.



  <I> Example: </I> A diazo solution of 22 g 1,4-diethoxy-2-amido-5 is added to a soda-alkaline solution of 9 gi-proline and 25 g soda at <B> 15 '</B> -benzoylamidobenzene run. The coupling will soon be over. The diazoamido compound, some of which separates out by itself, is precipitated by adding table salt.

      When dried, it is a weakly colored, water-soluble powder and is a valuable product for dyeing purposes.
