Description

  

  Verfahren zur Herstellung einer festen     Diazoazoverbindnng.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung einer festen     Diazo-          azoverbindung,    das dadurch gekennzeichnet  ist, dass man aus einer Lösung der     Diazover-          bindung    des     Aminoazokörpers        4-Nitro-2-meth-          oxybenzol    -     azo    - 3 -     amino-4-methoxy-l-methyl-          benzol    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 316 Teilen des     p-Aminoazokör-          pers        4-Nitro-2-metboxybenzol-azo-3-amino-4-          methoxy-l-methylbenzol    hergestellte     Diazo-          niumchloridlösung    wird mit Hilfe von 100  Teilen Chlorzink und einer genügenden Menge  Kochsalz gefällt. Das abgeschiedene Chlor-         zinkdoppelsalz    wird getrocknet und gleich  mässig mit geeigneten Verdünnungsmitteln  gemischt.



  Method of making a solid diazoazo compound. The present patent relates to a process for the production of a solid diazo-azo compound, which is characterized in that 4-nitro-2-methoxybenzene-azo-3-amino-4-methoxy is obtained from a solution of the diazo compound of the amino-azo body -l-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 316 parts of the p-aminoazo body 4-nitro-2-metboxybenzene-azo-3-amino-4-methoxy-1-methylbenzene is made with the aid of 100 parts Zinc chloride and a sufficient amount of table salt are precipitated. The separated zinc chloride double salt is dried and mixed evenly with suitable thinners.

PATENTANSPRUCH: Verfahren zur Herstellung einer festen Diazoazoverbindung, dadurch gekennzeichnet, dass man aus einer Lösung der Diazoverbin- dung des Aminoazokörpers 4-Nitro-2-methoxy- benzol-azo-3-amino-4-methoxy-l-methylbenzol durch Zusatz von Chlorzink ein festes Chlor zinkdoppelsalz der Formel EMI0001.0030 abscheidet. Die so erhaltene feste Diazoazoverbindung ist beständig. Sie ist ein orangebraunes Pul ver, das sich im Wasser mit bräunlicher Farbe löst. - Claim: A process for the production of a solid diazoazo compound, characterized in that 4-nitro-2-methoxy-benzene-azo-3-amino-4-methoxy-1-methylbenzene is converted from a solution of the diazo compound of the aminoazo body by adding zinc chloride a solid chlorine zinc double salt of the formula EMI0001.0030 separates. The solid diazoazo compound thus obtained is stable. It is an orange-brown powder that dissolves in water with a brownish color. -
