PATENTAMT.PATENT OFFICE.
Beim Erhitzen von p-Amidophenol mit salzsaurem p-Amidophenol entsteht neben p-Dioxydiphenylamin eine gefärbte Verbindung. Es wurde nun die Beobachtung gemacht, dafs unter gewissen Umständen ein drittes Product gebildet wird, welches in hervorragender Weise zur Darstellung schwefelhaltiger Baumwollfarbstoffe geeignet ist. Zur Herstellung dieses Körpers ist es vortheilhaft, auf 1 Molecül salzsaures p-Amidophenol mehr als 1 Molecül p-Amidophenol zu nehmen. Man erhitzt z. B. eine Mischung von 33 kg p-Amidophenol mit 15 kg salzsaurem p-Amidophenol 10 Stunden auf 160 bis i8o°. Die erkaltete Masse wirdWhen p-amidophenol is heated with hydrochloric acid p-amidophenol, p-dioxydiphenylamine is formed in addition to it a colored compound. It has now been observed that under certain circumstances a third product is formed, which is an excellent way to represent sulfur-containing cotton dyes suitable is. For the preparation of this body it is advantageous to add hydrochloric acid to 1 molecule Taking p-amidophenol more than 1 molecule of p-amidophenol. One heated z. B. a mixture of 33 kg of p-amidophenol with 15 kg of hydrochloric acid p-amidophenol for 10 hours to 160 to 180 °. The cooled mass will
mit verdünnter Salzsäure ausgekocht und filtrirt. Das Filtrat wird mit einer Lösung von Natriumacetat versetzt, bis kein Niederschlag mehr entsteht, dann aufgekocht und rasch filtrirt. Auf dem Filter bleibt die neue Verbindung zurück, während das nebenbei gebildete p-Dioxydiphenylamin im Filtrat enthalten ist, aus dem es sich beim Erkalten in schönen Krystallen ausscheidet.Boiled with dilute hydrochloric acid and filtered. The filtrate is made with a solution of sodium acetate added until no more precipitate forms, then boiled and quickly filtered. The new compound remains on the filter, while the p-dioxydiphenylamine formed in the process is contained in the filtrate, from which it turns into beautiful crystals when it cools ruled out.
In der folgenden Tabelle sind einige Eigenschaften der bisher durch Erhitzen von Mischungen des p-Amidophenols mit seinem salzsauren Salze erhaltenen Körper zusammengestellt. In the following table are some properties of the so far obtained by heating Mixtures of p-amidophenol with its hydrochloric acid salts obtained body compiled.
