Description

  

  Verfahren zur Herstellung einer festen     Diazoazoverbindung.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung einer festen     Diazo-          azoverbindung,    das dadurch gekennzeichnet  ist, dass man aus einer Lösung der     Diazo-          verbindung    des     Aminoazokörpers        4-Nitro-2-          methylbenzol-azo    -3 -     amino-    4-     methoxy-1-me-          thylbenzol    durch Zusatz von Chlorzink ein  festes     Chlorzinkdoppelsalz    der Formel  
EMI0001.0013     
    abscheidet.

    Die so erhaltene feste     Diazoazoverbindung     ist ein     orangebraunes    Pulver, das sich in  Wasser mit bräunlicher Farbe löst.  <I>Beispiel:</I>  Eine aus 300 Teilen des     p-Aminoazo-          körpers        4-Nitro-2-methylbenzol-azo-3-amino-4-          metho$y-l-methylbenzol    hergestellte     Diazoni-          umchloridlösung    wird mit Hilfe von 100 Teilen  Chlorzink und einer genügenden Menge Koch  salz gefällt. Das abgeschiedene Chlorzirik-         doppelsalz    wird getrocknet und gleichmässig  mit geeigneten Verdünnungsmitteln gemischt.



  Process for producing a solid diazoazo compound. The present patent relates to a process for the preparation of a solid diazo-azo compound, which is characterized in that from a solution of the diazo compound of the amino-azo body, 4-nitro-2-methylbenzene-azo -3-amino-4-methoxy-1 -Methylbenzene by adding zinc chloride a solid zinc chloride double salt of the formula
EMI0001.0013
    separates.

    The solid diazoazo compound thus obtained is an orange-brown powder which dissolves in water with a brownish color. <I> Example: </I> A diazonium chloride solution prepared from 300 parts of the p-aminoazo body 4-nitro-2-methylbenzene-azo-3-amino-4-metho $ yl-methylbenzene is added with the aid of 100 parts Zinc chloride and a sufficient amount of cooking salt are precipitated. The separated chlorine double salt is dried and evenly mixed with suitable diluents.

PATENTANSPRUCH: Verfahren zur Herstellung einer festen Diazoazoverbindung, dadurch gekennzeichnet, dass man aus einer Lösung der Diazover- bindung des Aminoazokörpers 4-Nitro-2-me- thylbenzol - a zo - 3 -amino-4-methogy-l-methyl- benzol durch Zusatz von Chlorzink ein festes Chlorzinkdoppelsalz der Formel EMI0001.0034 abscheidet. Die so erhaltene feste Diazoazoverbindung ist beständig. Claim: Process for the production of a solid diazoazo compound, characterized in that from a solution of the diazo compound of the aminoazo body 4-nitro-2-methylbenzene - a zo - 3-amino-4-methogy-l-methylbenzene through Addition of zinc chloride a solid zinc chloride double salt of the formula EMI0001.0034 separates. The solid diazoazo compound thus obtained is stable. Sie ist ein orangebraunes Pulver, das sich im Wasser mit bräunlicher Farbe löst. It is an orange-brown powder that dissolves in water with a brownish color.
