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     Aminoazokörpei,s        Paranitro-          benzol-azo-2-amino-1.4-dimethoxybenzol    durch  Zusatz von Chlorzink ein festes     Chlorzink-          doppelsalz    der Formel:  
EMI0001.0012     
    abscheidet.

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



  <I>Beispiel:</I>  Eine aus<B>302</B> Teilen des     p-Aminoazo-          körpers:        Paranitrobenzol-azo-2-amino-1.4-          dimethoxybenzol    hergestellte     Diazoniumehlo-          ridlösung    wird mit Hilfe von<B>100</B> 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 preparation of a solid diazo-azo compound, which is characterized in that from a solution of the diazo compound of the aminoazo body, paranitrobenzene-azo-2-amino-1,4-dimethoxybenzene is added by adding zinc chloride a solid zinc chloride double salt of the formula:
EMI0001.0012
    separates.

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



  <I> Example: </I> A diazonium chloride solution produced from <B> 302 </B> parts of the p-aminoazo body: Paranitrobenzene-azo-2-amino-1,4-dimethoxybenzene is converted with the aid of <B> 100 </B> Parts of zinc chloride and a sufficient amount of table salt are precipitated. The separated zinc chloride double salt is dried and evenly mixed with suitable thinners

PATENTANSPRUCH: Verfahren zur Herstellung einer festen Diazoazoverbindung, dadurch gekennzeichnet, dass man aus einer Lösung der Diazoverbin- dung des Amiiioazokörpers Paranitrobenzol- azo-2-amino-1.4-diinethoxybenzol durch Zu satz von Chlorzink ein festes Chlorzink- doppelsalz der Formel- EMI0001.0033 abscheidet. Die so erhaltene feste Diazoazoverbindung ist beständig. Sie ist ein rotbraunes Pulver, das sich in 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 of the formula is obtained from a solution of the diazo compound of the aminoazo body paranitrobenzene-azo-2-amino-1,4-diinethoxybenzene by adding zinc chloride. EMI0001.0033 separates. The solid diazoazo compound thus obtained is stable. It is a red-brown powder that dissolves in water with a brownish color.
