Das Verfahren beruht auf der Beobachtung, dafs Farbstoffe von werthvollen Eigenschaften entstehen, wenn Fuchsin und Methylviolett mit einer Mischung von Salpeter- und Schwefelsäure behandelt werden.The process rests on the observation that dyes have valuable properties arise when fuchsine and methyl violet with a mixture of nitric and sulfuric acids be treated.
Man verfährt folgendermafsen:Proceed as follows:
40,47 kg krystallisirtes Methyl violett werden in 200 bis 250 kg Schwefelsäure von 66° B. gelöst. Zu der auf o° erkalteten Lösung wird langsam ein gleichfalls abgekühltes Gemisch von 10 kg 36 procentiger Salpetersäure und 20 bis 30 kg concentrirter Schwefelsäure unter Umrühren hinzugefügt. Nach mehrstündigem Stehen wird mit Wasser auf 4000 1 verdünnt, die Säure mit Natron oder kohlensaurer Magnesia neutralisirt und die ausgeschiedene Base auf Filtern gesammelt und ausgewaschen.40.47 kg of crystallized methyl turn violet dissolved in 200 to 250 kg sulfuric acid of 66 ° B. To the solution cooled to o ° slowly a likewise cooled mixture of 10 kg of 36 percent nitric acid and Add 20 to 30 kg of concentrated sulfuric acid while stirring. After several hours Standing is diluted to 4000 l with water, the acid with sodium bicarbonate or carbonate Magnesia neutralized and the precipitated base collected on filters and washed out.
Das salzsaure Salz wird erhalten, wenn man die teigförmige Masse mit 116 oder 1 20 kg gewöhnlicher Salzsäure anrührt und dann trocknet. Der so erhaltene Farbstoff bildet ein bronzeglänzendes Pulver, das sich leicht in Wasser löst; derselbe färbt Wolle, Seide, sowie mit Gerbstoff gebeizte Baumwolle violettblau.The hydrochloric acid salt is obtained if the dough-like mass is 116 or 1 20 kg more common Stirring hydrochloric acid and then drying. The dye obtained in this way forms a shiny bronze Powder that easily dissolves in water; the same dyes wool, silk, as well as with Tannin-stained cotton violet blue.
Das krystallisirte Methylviolett kann in obigem Beispiel durch 39 kg gewöhnliches Methyl violett oder durch eine entsprechende Menge Benzylviolett ersetzt werden.The crystallized methyl violet can in the above example be made violet by 39 kg of ordinary methyl or replaced by an appropriate amount of benzyl violet.
Die entsprechenden Farbstoffe sind dem soeben beschriebenen ganz ähnlich.The corresponding dyes are very similar to the one just described.
33,75 kg Fuchsin oder 32 kg Rosanilin werden genau wie unter Beispiel I. angegeben behandelt. 33.75 kg of fuchsine or 32 kg of rosaniline are treated exactly as given in Example I.
Der nitrirte Farbstoff, der die Textilfaser granatroth färbt, wird am geeignetsten in Form von Paste verwendet.The nitrided dye, which dyes the textile fiber garnet-red, is most suitably shaped used by paste.
Beispiel III.Example III.
Wird in den angeführten Beispielen die Menge Salpetersäure verdoppelt, so entstehen weiter nitrirte Farbstoffe, die sämmtlich in Wasser schwerer löslich sind und deren Nuance etwas schwärzer ist. Im Ganzen besitzen diese höher nitrirten Farbstoffe ähnliche Eigenschaften wie die zuerst beschriebenen.If the amount of nitric acid is doubled in the examples given, more is produced nitrated dyes, all of which are less soluble in water, and their shade somewhat is blacker. On the whole, these more highly nitrated dyes have properties similar to the first described.
Ein besonderer Vorzug der sämmtlichen erwähnten Farbstoffe besteht darin, dafs dieselben die mit Gerbstoff gebeizte vegetabilische Faser nur an den gebeizten Stellen färben, nicht aber an den ungeheizten, so dafs die durch Aetzdruck (Enlevage) erzielten Zeichnungen schön weifs auf dem gefärbten Grunde erscheinen. Die erhaltenen Färbungen sind ebenso echt gegen Licht und Seife, wie die der nicht nitrirten Farbstoffe.A particular advantage of all the dyes mentioned is that they are dye the vegetable fibers stained with tannin only in the stained areas, but not on the unheated ones, so that the drawings obtained by etching (Enlevage) are beautiful white appear on the colored ground. The dyeings obtained are also fast against Light and soap, like those of the non-nitrided dyes.
