PATENTAMTPATENT OFFICE
. Im Patent 174905 ist ein Verfahren zur Darstellung von o-Oxymonoazofarbstoffen beschrieben, darin bestehend, daß man die Diazoverbindungen halogensubstituierter o-Aminophenole in Gegenwart von Kalkhydrat mit ι i'8-Chlornaphtolsulfosäuren kombiniert.. Patent 174905 describes a process for the preparation of o-oxymonoazo dyes, consisting of the diazo compounds of halogen-substituted o-aminophenols combined in the presence of hydrated lime with ι i'8-Chlornaphtolsulfoäuren.
Es wurde nun gefunden, daß man mit gleichem Erfolge die Kombination in Gegenwart von Barythydrat, Strontiumoxydhydrat, Zinkoxydhydrat ausführen kann. Die so erhältlichen Farbstoffe sind identisch mit denen des Hauptpatentes.It has now been found that the combination in the present can be used with the same success of barythydrate, strontium oxide hydrate, zinc oxide hydrate. The so available Dyes are identical to those of the main patent.
In folgender Weise kann man die Farbstoffe gewinnen:The dyes can be obtained in the following way:
Beispiel I. 17,8 kg o-p-Dichlor-o-aminophenol werden mit 30 kg Salzsäure von etwa 2O° Be. und 6,9 kg Nitrit diazotiert und eingetragen in eine Lösung von 39 kg des Dinatriumsalzes der 1 · 8-Chlornaphtol-4 · 6-disulfosäure, die mit 30 kg Barythydrat versetzt ist. Nach ungefähr 8 stündigem Rühren filtriert man ab, macht die Lösung sauer und fällt den Farbstoff durch Kochsalz aus.Example I. 17.8 kg of o-p-dichloro-o-aminophenol are with 30 kg hydrochloric acid of about 20 ° Be. and 6.9 kg of nitrite diazotized and registered in a solution of 39 kg of the disodium salt of 1x8-chloronaphthol-4x6-disulfonic acid, which is mixed with 30 kg of baryta hydrate. After about 8 hours of stirring, the solution is filtered off, made acidic and the dye precipitates from table salt.
Der Farbstoff ist identisch mit dem nach dem Hauptpatent mit Kalkhydrat hergestellten.The dye is identical to that made with hydrated lime according to the main patent.

Nach Beendigung der Farbstoffbildung filtriert man und fällt aus der Lösung den Farbstoff durch Zugabe von Salzsäure und Kochsalz aus. Der Farbstoff ist identisch mit dem nach dem Verfahren des Hauptpatentes in Gegenwart von Kalkhydrat hergestellten.2O ° Be. and 6.9 kg of nitrite diazotized and registered in a solution of 39 kg of the disodium salt of 1 · 8-chloronaphthol-3 · 6-disulfonic acid, in which one has stirred about 30 kg of zinc oxide hydrate. After the formation of the dye has ended, it is filtered and the dye is precipitated from the solution by adding hydrochloric acid and common salt. The dye is identical to that produced by the process of the main patent in the presence of hydrated lime.
