Description
Verfahren zur Herstellung eines Wollfarbstoffes. Vorliegendes Patent bezieht sich auf ein Verfahren zur Herstellung eines Wollfarb- stoffes, dadurch gekennzeichnet, dass man 1-Amino-4-bromanthrachinon-2-sulfonsäure in wässeriger Lösung in Gegenwart von säure bindenden Mitteln und eines Katalysators mit 4.9'-Diamino-diphenylamin-2-sulfosäure kondensiert.
Der Farbstoff löst sich auch ohne Zusatz von Alkalien sehr leicht in Wasser und färbt aus saurem (am besten essigsaurem) Bade Wolle in graublauen Tönen an, die ausge zeichnete Echtheiten besitzen. Die Lösung in konzentrierter Schwefelsäure ist schwach blau gefärbt, nach Zusatz von Paraformal= dehyd wird sie grün. Durch Behandlung mit alkalischen Reduktionsmitteln lässt sich die Sulfosäuregruppe des Anthrachinonkerns ab spalten.
<I>Beispiel:</I> 50 kg 1-amino-4-brom-anthrachinon-2-sul- fosaures Natrium werden mit 50 kg 4. 4'-dia- mino-diphenylamin-2-sulfosaurem Natrium bei Gegenwart von 50 kg Soda und 5 kg Kupfer vitriol in 3000 Liter Wasser durch mehr stündiges Rühren bei 70-800 kondensiert. Die gefärbte Lösung wird ausgesalzen und das ausgeschiedene Reaktionsprodukt noch mals in 3000 Liter Wasser angeschlämmt beziehungsweise gelöst. Der reine Farbstoff lässt sich durch Zusatz von 20 kg konzentrierter Salzsäure vollständig ausfällen und init Wasser auswaschen.
Process for the preparation of a wool dye. The present patent relates to a process for the production of a wool dye, characterized in that 1-amino-4-bromoanthraquinone-2-sulfonic acid in aqueous solution in the presence of acid-binding agents and a catalyst with 4.9'-diamino-diphenylamine 2-sulfonic acid condensed.
The dye dissolves very easily in water, even without the addition of alkalis, and stains acidic (preferably acetic acid) bath wool in gray-blue shades that have excellent fastness properties. The solution in concentrated sulfuric acid is pale blue in color; after adding paraformaldehyde, it turns green. The sulfonic acid group of the anthraquinone nucleus can be split off by treatment with alkaline reducing agents.
<I> Example: </I> 50 kg of 1-amino-4-bromo-anthraquinone-2-sulphate of sodium are mixed with 50 kg of 4'-diamino-diphenylamine-2-sulphonic acid in the presence of 50 kg of soda and 5 kg of copper vitriol condensed in 3000 liters of water by stirring for more hours at 70-800. The colored solution is salted out and the precipitated reaction product is slurried or dissolved again in 3000 liters of water. The pure dye can be completely precipitated by adding 20 kg of concentrated hydrochloric acid and washed out with water.
