Description

  

  Verfahren zur     Iferstellung    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     Diazover-          bindung    des     Aminoazokörpers        Paranitrobenzol-          azo-3-amino-4-äthoxy-1-methylbenzol    durch  Zusatz von Chlorzink ein festes Chlorzink  doppelsalz der Formel  
EMI0001.0010     
    abscheidet.

    Die so erhaltene feste     Diazoazoverbindung     ist ein     orangebraunes    Pulver, das sich in  Wasser mit bräunlicher Farbe löst.  <I>Beispiel:</I>  Eine aus 300 Teilen des     p-Aminoazo-          körpers        Paranitrobenzol-azo-3-amino-4-ätho-          xy-l-methylbenzol    hergestellte     Diazonium-          chloridlösung    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 the production of 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 paranitrobenzene-azo-3-amino-4-ethoxy-1-methylbenzene is converted from a solution of the diazo compound of the aminoazo body by adding chlorozinc a solid zinc chloride double salt of the formula
EMI0001.0010
    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 300 parts of the p-aminoazo body paranitrobenzene-azo-3-amino-4-ethoxy-1-methylbenzene is mixed with 100 parts of zinc chloride and a sufficient Plenty of cooking salt like. 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-3-amino-4-äthoxy-l-methylbenzol durch Zusatz von Chlorzink ein festes Ohlorzink- doppelsalz der Formel EMI0001.0028 abscheidet. Die so erhaltene feste Diazoazoverbindung ist beständig. Sie ist ein orangebraunes Pulver; das sich in Wasser mit bräunlicher Farbe löst. Claim: A process for the preparation of a solid diazoazo compound, characterized in that a solid oxyzinc double salt of the formula is obtained from a solution of the diazo compound of the aminoazo body paranitrobenzene-azo-3-amino-4-ethoxy-1-methylbenzene by adding chlorozinc EMI0001.0028 separates. The solid diazoazo compound thus obtained is stable. It is an orange-brown powder; which dissolves in water with a brownish color.
