Description
Verfahren zur Darstellung von Farbstoffen der Anthrachinonreihe. Behandelt man die z. B. nach dem Verfahren des Patents 329246 aus ß-Arylaminoanthrachinonen und aromatischen Aminoverbindungen darstellbaren azinartigen Kondensationsprodukte mit sulfierenden Mitteln, so erhält man neue Verbindungen, die der verschiedensten Verwendung fähig und z. B. wertvolle Wollfarbstoffe sind. Je nach den angewandten Bedingungen, ob man z. B. bei An-oder Abwesenheit von Borsäure, mit wasserhaltiger oder konzentrierter Schwefelsäure, mit Oleum oder ChIorsulfonsäure arbeitet, kann man verschiedenartige Produkte erhalten.Process for the preparation of dyes of the anthraquinone series. Treated one the z. B. by the method of the patent 329246 from ß-arylaminoanthraquinones and aromatic amino compounds, azin-like condensation products can be prepared with sulphurizing agents, new compounds of the most varied are obtained Usable and z. B. are valuable wool dyes. Depending on the applied Conditions, whether one z. B. in the presence or absence of boric acid, with aqueous or concentrated sulfuric acid, works with oleum or chlorosulfonic acid different kinds of products can be obtained.
Beispiel i.Example i.
2 Teile des Kondensationsproduktes aus 2-Phenylaminoanthrachinon und Anilin werden in 2o Teilen Oleum 23prozentig eingetragen. Man rührt ungefähr 22 Stunden bei etwa 8o°, gießt sodann in kaltes Wasser, behandelt in der Kälte mit einer wässerigen- Lösung von Ferrosulfat einige Zeit und salzt durch Zusatz von Kochsalzlösung den Farbstoff aus.2 parts of the condensation product of 2-phenylaminoanthraquinone and 23 percent of aniline is entered in 20 parts of oleum. It stirs about 22 Hours at about 80 °, then pour into cold water, treated in the cold with an aqueous solution of ferrous sulfate for some time and salted by the addition of Saline solution removes the dye.
Das neue Produkt färbt Wolle aus saurem Bade in blaugrünen Tönen von hervorragender Lichtechtheit an. Analog verfährt man bei Verwendung anderer Kondensationsprodukte der eingangs gekennzeichneten Art.The new product dyes wool from an acid bath in blue-green shades of excellent lightfastness. The same procedure is used when using other condensation products of the type identified at the beginning.
Beispiel e.Example e.
2 Teile des Kondensationsproduktes aus 2-Phenylaminoanthrachinon und Anilin werden in ein Gemisch von 4 Teilen entwässerter Borsäure und 2o Teilen Oleum 23 prozentig eingetragen, worauf das Gemisch ungefähr goStunden .bei etwa go ° gehalten wird. Nach dem Abkühlen wird in Wasser eingerührt und der Farbstoff in geeigneter Weise aufgearbeitet. Er färbt Wolle in echten reinblauen Tönen an.2 parts of the condensation product of 2-phenylaminoanthraquinone and Aniline is dissolved in a mixture of 4 parts of dehydrated boric acid and 2o parts of oleum 23 percent entered, whereupon the mixture was held at about go ° for about go hours will. After cooling, the mixture is stirred into water and the dye in a suitable manner Way worked up. He dyes wool in real pure blue tones.
Der fertige Farbstoff kann gegebenenfalls einer weiteren Behandlung mit sulfierenden Mitteln unterworfen werden.The finished dye can optionally undergo further treatment be subjected to sulphurizing agents.
