Description
<B>Zusatzpatent</B> zum Hauptpatent Nr. 209166. Verfahren zur Herstellung eines sauren Wollfarbstoffes der Anthrachinonreihe. Gegenstand dieses Zusatzpatentes ist ein Verfahren zur Herstellung eines sauren Woll- farbstoffes 'der Anthrachinonreihe, welches darin besteht,
dass man auf das Konden sationsprodukt aus 1-Amino-4-bromanthra- chinon-2-sulfonsäuT.e und. 3'-Amino-4'-me- thyl-o-benzoyl-benzoesäure Methogybenzo@l in Gegenwart von Schwefelsäure einwirken lässt.
Die Umsetzung wird zweckmässig so durchgeführt, dass,die Reaktionskomponenten in Gegenwart von konzentrierter Schwefel säure während einiger Stunden bei einer Temperatur von etwa 0 C bis<B>25'C</B> verrührt werden.
Der so erhaltene neue Farbstoff dient zum Färben der tierischen Faser. Er wird in Form eines dunkelblauen, wasserlöslichen Pulvers erhalten und färbt Wolle in grün stiehig blauen Tönen.
<I>Beispiel:</I> 10 Gewichtsteile des nach dem Verfah ren der Schweizer Patentschrift Nr. 153201 erhältlichen Kondensationsproduktes aus 1-Amino -4 - brom-anthrachinon-2-sulfonsäure und 3'-Amino-4'-methyl-o-benzoylbenzoe- siure werden in. 100 Gewichtsteilen konzen trierter Schwefelsäure gelöst und bei 20' C mit 10 Gewichtsteilen Methogybenzol eine Stunde verrührt. Das Reaktionsgemisch
wird aus Eis gegeben; der in dunkelblauen Flocken ausgeschiedene Farbstoff wird ab gesaugt. Zur Reinigung löst man ihn in ver dünntem Ammoniak, filtriert und fällt ihn mit verdünnter Salzsäure aus. Er wird in Form eines dunkelblauen, wasserlöslichen Pulvere erhalten. Der Farbstoff färbt Wolle in grünstichig blauen Tönen, .die sehr wasser-, wasch- und lichtbeständig sind.
<B> Additional patent </B> to main patent no. 209166. Process for the production of an acidic wool dye of the anthraquinone series. The subject of this additional patent is a process for the production of an acidic wool dye of the anthraquinone series, which consists in
that on the condensation product of 1-amino-4-bromanthraquinone-2-sulfonsäuT.e and. 3'-Amino-4'-methyl-o-benzoyl-benzoic acid Methogybenzo @ l can act in the presence of sulfuric acid.
The reaction is expediently carried out in such a way that the reaction components are stirred in the presence of concentrated sulfuric acid for a few hours at a temperature of about 0 ° C. to 25 ° C.
The new dye thus obtained is used to dye the animal fiber. It is obtained in the form of a dark blue, water-soluble powder and dyes wool in green, deep blue tones.
<I> Example: </I> 10 parts by weight of the condensation product of 1-amino -4-bromo-anthraquinone-2-sulfonic acid and 3'-amino-4'-methyl-o, obtainable by the method of Swiss patent specification No. 153201 Benzoylbenzoic acid are dissolved in 100 parts by weight of concentrated sulfuric acid and stirred at 20 ° C. with 10 parts by weight of methogybenzene for one hour. The reaction mixture
is given from ice; the dye separated in dark blue flakes is sucked off. To clean it, it is dissolved in dilute ammonia, filtered and precipitated with dilute hydrochloric acid. It is obtained in the form of a dark blue, water-soluble powder. The dye dyes wool in greenish blue tones, which are very water, wash and lightfast.
