Description

  

  Verfahren zur Herstellung einer festen     Diazoazorerbindung.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung einer festen     Di-          azoazoverbindung,    das dadurch gekennzeichnet  ist, dass man aus einer Lösung der     Diazo-          verbindung    des     Aminoazokörpers        Metanitro-          benzol-azo-3-amino-4-methoxy-l-methylberrzol     durch Zusatz von Chlorzink ein festes Chlor  zinkdoppelsalz der Formel  
EMI0001.0009     
    abscheidet.  Die so erhaltene feste     Diazoazoverbindung     ist ein gelbbraunes Pulver, das sich in Was  ser mit bräunlicher Farbe löst.

      <I>Beispiel:</I>  Eine aus 286 Teilen des     p-Amirroazokör-          pers        Metanitrobenzol-azo-3-amino-4-methoxy-          1-methylbenzol    hergestellte     Diazoniumchlorid-          lösung    wird mit Hilfe von 100 Teilen Chlor  zink und einer genügenden Menge Kochsalz    gefällt. Das abgeschiedene     Chlorzinkdoppel-          salz    wird getrocknet und gleichmässig mit  geeigneten Verdünnungsmitteln gemischt.



  Method of making a solid diazoazor compound. The present patent relates to a process for the preparation of a solid diazoazo compound, which is characterized in that metanitrobenzene-azo-3-amino-4-methoxy-1-methylberrzene is converted from a solution of the diazo compound of the aminoazo body by adding of chlorine zinc a solid chlorine zinc double salt of the formula
EMI0001.0009
    separates. The solid diazoazo compound thus obtained is a yellow-brown powder which dissolves in water with a brownish color.

      <I> Example: </I> A diazonium chloride solution prepared from 286 parts of the p-amirroazo body metanitrobenzene-azo-3-amino-4-methoxy-1-methylbenzene is made into zinc with the aid of 100 parts of chlorine and a sufficient amount Table 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 Metanitrobenzol- azo-3-amino-4-methoxy-l-methylbenzol durch Zusatz von Chlorzink ein festes Chlorzink doppelsalz der Formel EMI0001.0026 abscheidet. Die so erhaltene feste Diazoazoverbindung ist beständig. Sie ist ein gelbbraunes Pulver, das sich im 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 metanitrobenzene-azo-3-amino-4-methoxy-1-methylbenzene by adding zinc chloride EMI0001.0026 separates. The solid diazoazo compound thus obtained is stable. It is a yellow-brown powder that dissolves in water with a brownish color.
