Description

  

  Verfahren zur Herstellung einer festen     Diazoazoverhindung.       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        Paranitroben-          zol-azo-2-amino-1.4-diäthoxybeiizol    durch Zu  satz von Chlorzink ein festes     Chlorzinkdoppel-          salz    der Formel:  
EMI0001.0011     
    abscheidet.

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



  <I>Beispiel:</I>  Eine aus 330 Teilen des     p-Aminoazokörpers          Pai-anitrobenzol-azo-2-amino-1.    4-     diäthoxyben-          zol    hergestellte     Diazoniumchloridlösung    wird  mit Hilfe von 100 Teilen     Chlorzicik    und einer  genügenden Menge Kochsalz gefällt. Das ab  geschiedene     Chlorzinkdoppelsalz    wird ge-    trocknet und gleichmässig mit geeigneten  Verdünnungsmitteln gemischt.



  Process for the preparation of 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 paranitrobenzene-azo-2-amino-1,4-diethoxybeiizole is added from a solution of the diazo compound of the aminoazo body by adding zinc chloride solid zinc chloride double salt of the formula:
EMI0001.0011
    separates.

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



  <I> Example: </I> One of 330 parts of the p-aminoazo body Pai-anitrobenzene-azo-2-amino-1. 4-diethoxybenzene-made diazonium chloride solution is precipitated with the help of 100 parts of Chlorzicik and a sufficient amount of common salt. 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 Aminoazokörpers Paranitrobenzol- azo-2-amino-1.4-diäthoxybenzol durch Zusatz von Chlorzink ein festes Chlorzinkdoppelsalz der Formel: EMI0001.0027 abscheidet. Die so erhaltene feste Diazoazoverbindung ist beständig. Sie ist ein rotbraunes Pulver, das sich in Wasser mit bräunlicher Farbe löst. PATENT CLAIM: 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-diethoxybenzene by adding zinc chloride. EMI0001.0027 separates. The solid diazoazo compound thus obtained is stable. It is a red-brown powder that dissolves in water with a brownish color.
