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        Metanitro-          benzol-azo-2-amino-1.4-ditnethoxybenzol    durch  Zusatz von Chlorzink ein festes Chlorzink  doppelsalz der Formel:  
EMI0001.0009     
    abscheidet.

    Die so erhaltene feste     Diazoazoverbindung     ist ein rotbraunes Pulver, das sich in     Wasser     mit bräunlicher Farbe löst.  



       Beispiel:     Eine aus 302 Teilen des     p-Aminoazo-          körpers    :     14Zetariitrobenzol-azo-2-amino-1.4-          dimethoxybenzol    hergestellte     Diazoniumchlo-          ridlösung    wird mit Hilfe von 100 Teilen  Chlorzink und einer genügenden Menge Koch-    salz gefällt: Das abgeschiedene Chlorzink  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 production of a solid diazo-azo compound, which is characterized in that a solid metanitrobenzene-azo-2-amino-1,4-di-methoxybenzene is obtained from a solution of the diazo compound of the aminoazo body by adding zinc chloride Chlorine zinc double salt of the formula:
EMI0001.0009
    separates.

    The solid diazoazo compound thus obtained is a red-brown powder which dissolves in water with a brownish color.



       Example: A diazonium chloride solution made from 302 parts of the p-aminoazo body: 14zetariitrobenzene-azo-2-amino-1,4-dimethoxybenzene is precipitated with the help of 100 parts of zinc chloride and a sufficient amount of common salt: The precipitated 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 '' etanitrobenzol- azo-2-amino-1. 4-dimethoxy benzol durch Zu satz von Chlorzink ein festes Chlorzink doppelsalz der Formel: EMI0001.0030 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 '' etanitrobenzene-azo-2-amino-1. 4-dimethoxy benzene by adding zinc chloride a solid zinc chloride double salt of the formula: EMI0001.0030 separates. The solid diazoazo compound thus obtained is stable. Sie ist ein rotbraunes Pulver, das sich im Wasser mit bräunlicher Farbe löst. It is a red-brown powder that dissolves in water with a brownish color.
