Verfahren zur Darstellung eines rotbraunen Küpenfarbstoffs.Process for the preparation of a red-brown vat dye.
Zusatz zum Patent 244705.Addendum to patent 244705.
Patentiert im Deutschen Reiche vom 2. April 1912 ab. Längste Dauer: 6. Februar 1926.Patented in the German Empire on April 2, 1912. Longest duration: February 6, 1926.
Es wurde gefunden, daß man durch die Einwirkung von Metallchloriden oder Ätzalkali auf i-Anthrachinonyl-5-aminoanthrachinoni · 2 - thioxanthon, welches durch Umsetzung von 5-Aminoanthrachinon-i · 2-thioxanthon mit i-Chloranthrachinon erhältlich ist, einen wertvollen rotbraunen Küpenfarbstoff erhält.It has been found that by the action of metal chlorides or caustic alkali to i-anthraquinonyl-5-aminoanthraquinoni · 2 - thioxanthone, which by reacting 5-aminoanthraquinone-i · 2-thioxanthone with i-Chloranthraquinone is a valuable one receives red-brown vat dye.
I. 5 Teile i-Anthrachinonyl-5-aminoanthrachinon -1 · 2 - thioxanthon (siehe Patentschrift 231854) und 25 Teile Aluminiumchlorid werden im Laufe einer halben Stunde auf i8o° erhitzt. Die flüssig werdende Masse wird unter Rühren noch 15 Minuten auf 180 bis 1900 erhitzt und nach dem Erkalten mit verdünnter Salzsäure ausgezogen. Der so gewonnene Farbstoff stellt ein braunes Pulver dar, das sich aus a - Chlornaphtalin Umkristallisieren läßt. Er löst sich in konzentrierter Schwefelsäure mit rotvioletter Farbe und gibt mit alkalischem Hydrosulfit eine braune Küpe, aus der Baumwolle nach dem Verhängen tait klarer brauner Farbe von hervorragender Echtheit angefärbt wird.I. 5 parts of i-anthraquinonyl-5-aminoanthraquinone -1 · 2-thioxanthone (see patent specification 231854) and 25 parts of aluminum chloride are heated to 180 ° over the course of half an hour. The becomes liquid mass is heated with stirring for another 15 minutes at 180 to 190 0 and extracted after cooling with dilute hydrochloric acid. The dye thus obtained is a brown powder, which consists of a - can chloronaphthalene recrystallization. It dissolves in concentrated sulfuric acid with a red-violet color and, with alkaline hydrosulphite, gives a brown vat from which cotton is dyed with a clear brown color of excellent fastness after hanging.
II. 150 Teile Ätzkali werden bei 170 bis 180° geschmolzen und im Laufe von etwa 10 Minuten 15 Teile »Thioxanthon« eingerührt. Dann wird noch kurze Zeit auf 200 ° erhitzt, wobei sich das Reaktionsprodukt zusammenballt und auf dem Ätzkali schwimmt. Es wird abgetrennt, in Wasser nach dem Erkalten gelöst und durch Einleiten von Luft der braune Farbstoff zur Ausscheidung gebracht.II. 150 parts of caustic potash are at 170 to Melted at 180 ° and stirred in 15 parts of “thioxanthone” in the course of about 10 minutes. The mixture is then heated to 200 ° for a short time, during which the reaction product agglomerates and floats on the caustic potash. It is separated off, dissolved in water after cooling and by introducing air of the brown dye brought to excretion.
