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     Diazover-          binduug    des     Aminoazokörpers    3-Nitro-6-meth       oxybenzol-azo-3-amino-4-äthoxy-l-methylben-          zot    durch Zusatz von Chlorzink ein festes       Chlorzinkdoppelsalz    der Formel  
EMI0001.0011     
    abscheidet.

    Die so erhaltene feste     Diazoazoverbindung     ist ein rotbraunes Pulver, das sieh in Wasser  mit bräunlicher Farbe löst.         Beispiel       Eine aus 330 Teilen des     p-Aminoazokör-          pers        3-Nitro-6-methoxybenzol-azo-3-amino-4-          äthoxy-l-methylbenzol    hergestellte     Diazonium-          chloridlösung    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 3-nitro-6-methoxybenzene-azo-3-amino-4-ethoxy-3-amino-4-ethoxy is obtained from a solution of the diazo-compound of the aminoazo l-methylbenzot a solid zinc chloride double salt of the formula by adding zinc chloride
EMI0001.0011
    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 prepared from 330 parts of the p-aminoazo body 3-nitro-6-methoxybenzene-azo-3-amino-4-ethoxy-1-methylbenzene is converted into zinc chloride with the aid of 100 parts and a sufficient amount of cooking 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 3-Nitro-6-methoxy- benzol- azo - 3-amino-4-äthoxy-l-methyl benzol durch Zusatz von Chlorzink ein festes Chlor zinkdoppelsalz der Formel EMI0001.0030 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 3-nitro-6-methoxy-benzene-azo - 3-amino-4-ethoxy-l-methyl benzene is obtained from a solution of the diazo compound of the aminoazo body by adding Chlorzinc a solid chlorine zinc double salt of the formula EMI0001.0030 separates. The solid diazoazo compound thus obtained is stable. It is a red-brown powder that dissolves in water with a brownish color.
