Description

  

  Verfahren zur Herstellung einer wasserlöslichen     Diazoamidoverbindung.       Gegenstand des vorliegenden Patentes ist  ein Verfahren zur Herstellung einer wasser  löslichen     Diazoamidoverbindung.    Es ist da  durch gekennzeichnet, dass man     Piperidin-3-          sulfonsäure    auf dianotiertes     1-Amino-2-meth-          oxy-3-chlorberrzol    in Gegenwart eines säure  bindenden Mittels einwirken lässt.

      <I>Beispiel:</I>  In eine wässerige Lösung von 17     gr          piperidirr-3-srrlfonsaur#em        Natrium    und 20     gr     Soda lässt     rnan    bei<B>150</B> eine     Diazolösung    aus  11,4     gr-    1-     Amirro-    2     -methoxy-    5 -     chlor-berrzol     langsam zufliessen. Die Reaktion ist schnell  beendet. Aus der Lösung wird die gelblich  gefärbte     Diazoamidoverbindung    durch Zusatz    von Kochsalz ausgefällt. Sie ist in Wasser  löslich und ist ein wertvolles Produkt für       Färbereizwecke.  



  Process for producing a water-soluble diazoamido compound. The present patent relates to a process for the preparation of a water-soluble diazoamido compound. It is characterized in that piperidine-3-sulfonic acid is allowed to act on dianotated 1-amino-2-methoxy-3-chlorobenzene in the presence of an acid-binding agent.

      <I> Example: </I> In an aqueous solution of 17 grams of piperidir-3-sulfonic acid and 20 grams of soda, a diazo solution of 11.4 grams of amirro can be added at <B> 150 </B> - 2-methoxy- 5 - chloro-berrzol slowly flow in. The reaction ends quickly. The yellowish colored diazoamido compound is precipitated from the solution by adding sodium chloride. It is soluble in water and is a valuable product for dyeing purposes.
