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.
