BADISCHE ANILIN- UND SODA-FABRIK in LUDWIGSHAFEN a. Rh.BADISCHE ANILINE AND SODA FACTORY in LUDWIGSHAFEN a. Rh.
Patentirt im Deutschen Reiche vom 15. August 1899 ab.Patented in the German Empire on August 15, 1899.
Es wurde gefunden, dafs man blaugrüne, vermuthlich der Oxazinklasse angehörige Farbstoffe erhält, wenn man die salzsauren Nitrosoalkyl-m-amidophenole in wässeriger, verdünnt salzsaurer oder verdünnt essigsaurer Lösung bei Gegenwart gewisser Reductionsmittel erhitzt. Die Farbstoffbildung geht sehr rasch (in circa ι Stunde) mit guter Ausbeute vor sich, und die erhaltenen Producte sind von grofser Reinheit.It has been found that blue-green dyes, presumably belonging to the oxazine class, are found obtained when the hydrochloric acid nitrosoalkyl-m-amidophenols heated in aqueous, diluted hydrochloric acid or diluted acetic acid solution in the presence of certain reducing agents. The dye formation goes very quickly (in about 1 hour) with good yield, and the the products obtained are of great purity.
Als Reductionsmittel kann man Zinnchlorür oder Eisenoxydulsalze benutzen; die besten Resultate wurden bisher unter Verwendung des ersteren erhalten.Tin chloride or iron oxide salts can be used as reducing agents; the best Results have so far been obtained using the former.
Die so entstehenden Farbstoffe unterscheiden sich von allen ähnlichen bisher bekannten, und besonders von den aus dem Amidoalkyl-mamidophenol nach Möhlau (Berichte 25, 1066) entstehenden, durch ihr charakteristisches Verhalten gegen Mineralsäuren, wobei sie mit leuchtend grüner Farbe gelöst bezw. als lebhaft grüne Niederschläge gefällt werden.The resulting dyes differ from all similar previously known, and especially from the amidoalkyl-mamidophenol according to Möhlau (Reports 25, 1066) resulting from their characteristic behavior towards mineral acids, whereby they are with bright green color solved respectively. when vivid green rainfall is precipitated.
Des weiteren besitzen sie die Fähigkeit, mit Metallbeizen sehr beständige Lacke zu bilden; sie färben chromgebeizte Wolle und Seide in hervorragend walk- und lichtechten Tönen an. Die Färbungen können auch auf ungeheizter Wolle mit Chromsalzen nachbehandelt werden. Auch zum Färben von chromgebeizter Baumwolle und zum Baumwolldruck können sie, mit Chromsalzen gemischt, benutzt werden.Furthermore, they have the ability to form very stable lacquers with metal stains; they dye chrome-stained wool and silk in excellent mill-fast and lightfast shades. The dyeings can also be treated with chromium salts on unheated wool. They can also be used for dyeing chrome-stained cotton and for cotton printing, mixed with chromium salts, can be used.
Brauchbare Farbstoffe wurden bisher unter Anwendung von:Useful dyes have so far been made using:
Nitrosodimethyl-m-amidophenol,
Nitrosodiäthyl-m-amidophenol und
Nitrosomonoäthyl-m-amidophenol
erhalten.Nitrosodimethyl-m-amidophenol,
Nitrosodiethyl-m-amidophenol and
Nitrosomonoethyl-m-amidophenol
obtain.
12 Theile salzsaures Nitrosodiäthyl-m-amidophenol werden mit 80 Theilen Wasser übergössen, 5 Theile krystallisirtes Zinnchlorür hinzugefügt und unter Rühren circa 1 Stunde in kochendem Wasserbade erhitzt.12 parts of hydrochloric acid nitrosodiethyl-m-amidophenol are poured over with 80 parts of water, 5 parts of crystallized tin chloride are added and, while stirring, for about 1 hour heated in a boiling water bath.
Zur Isolirung des Farbstoffs wird die grüngefärbte Mischung mit verdünnter Salzsäure versetzt und die erhaltene Fällung abfiltrirt. Diese wird dann mit verdünnter kalter Sodalösung angerührt, wobei sie mit tiefblauer Farbe in Lösung geht; aus der filtrirten Lösung wird der Farbstoff durch Zusatz von Kochsalzlösung abgeschieden.To isolate the dye, the green-colored mixture is mixed with dilute hydrochloric acid added and the precipitate obtained is filtered off. This is then diluted with cold soda solution mixed, whereby it goes into solution with deep blue color; from the filtered solution the dye is deposited by adding saline solution.
In ganz ähnlicher Weise verfährt man bei Anwendung des Dimethyl- und des Monoäthylderivates an Stelle des im Beispiel benutzten Nitrosodiäthyl-m-amidophenols; der Farbstoff scheidet sich in ersterem Falle, wenn das Aussalzen warm vorgenommen wird, in grünglänzenden Nädelchen aus.A very similar procedure is followed when using the dimethyl and monoethyl derivatives instead of the nitrosodiethyl-m-amidophenol used in the example; the dye In the first case, if the salting out is carried out warm, it becomes green and shiny Needle off.
