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
