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        2-Nitro-4-          methylbenzol-        azo-3-amino-4-        methoxy-1-me-          thylbenzol    durch Zusatz von Chlorzink     -ein     festes     Chlorzinkdoppelsalz    der Formel  
EMI0001.0015     
    abscheidet.  Die so erhaltene feste     Diazoazoverbindung     ist ein     orangebraunes    Pulver, das sich in  Wasser mit bräunlicher Farbe löst.

         Beispiel:     Eine aus 300 Teilen des     p-Aminoazo-          körpers        2-Nitro-4-methylbeiizol-azo-3-amino-4-          methoxy-l-methylbenzol    hergestellte     Diazoni-          umchloridlösung    wird mit Hilfe von 100 Teilen       Chlorzink    und einer genügenden Menge Koch  salz gefällt. Das abgeschiedene Chlorzink-         doppelsalz    wird getrocknet und     gleiehmässig     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 aminoazo body 2-nitro-4-methylbenzene-azo-3-amino-4-methoxy-1-methylbenzene by adding chlorozinc a solid chlorozinc double salt of the formula
EMI0001.0015
    separates. The solid diazoazo compound thus obtained is an orange-brown powder which dissolves in water with a brownish color.

         Example: A diazonium chloride solution prepared from 300 parts of the p-aminoazo body 2-nitro-4-methylbeiizole-azo-3-amino-4-methoxy-1-methylbenzene is mixed with 100 parts of zinc chloride and a sufficient amount of common salt like. The separated zinc chloride double salt is dried and uniformly mixed with suitable diluents.

PATENTANSPRUCH: Verfahren zur Herstellung einer festen Diazoazoverbindung, dadurch gekennzeiehnet, dass man aus einer Lösung der Diazoverbindung des Aminoazokörpers 2-Nitro-4-methylbenzol- azo-3-amino-4-methoxy-l-niethylbenzol durch Zusatz von Chlorzink ein festes Chlorzink doppelsalz der Formel EMI0001.0035 abscheidet. Die so erhaltene feste Diazoazoverbindung ist beständig. Sie ist ein orangebraunes Pulver, das sich im Wasser mit bräunlicher Farbe löst. Claim: A process for the production of a solid diazoazo compound, characterized in that a solid zinc chloride double salt is obtained from a solution of the diazo compound of the aminoazo body 2-nitro-4-methylbenzene-azo-3-amino-4-methoxy-1-diethylbenzene by adding zinc chloride the formula EMI0001.0035 separates. The solid diazoazo compound thus obtained is stable. It is an orange-brown powder that dissolves in water with a brownish color.
