Verfahren zur Darstellung von Küpenfarbstoffen.Process for the preparation of vat dyes.
Zusatz zum Patent 205377 vom τ7· Januar 1907.*)Addition to patent 205377 from τ 7 January 1907. *)
Patentiert im Deutschen Reiche vom 2. Mai 1911 ab. Längste Dauer: 16. Januar 1922.Patented in the German Empire on May 2, 1911. Longest duration: January 16, 1922.
Bei der weiteren Ausbildung des durch das Patent 205377 geschützten Verfahrens wurde gefunden, daß man durch Kondensation von Nitroaceanthrenchinon mit 3-Oxy(i)thionaphten und nachfolgende partielle Reduktion einen Farbstoff erhält, welcher ungeheizte Baumwolle aus der Küpe in vollen, echten, schokoladenbraunen Tönen anfärbt. Dieses Resultat war überraschend, weil einerseits der Farbstoff ausAceanthrenchinon und3-Oxy(i)thionaphten nur farbschwache und waschunechte Färbungen liefert (vgl. auch Berl. Berichte 44, S. 854). Andererseits ist das entsprechende Kondensationsprodukt aus Nitroacenaphtenchinon nicht chlorecht, während der nach vorliegendem Verfahren erhältliche Farbstoff Färbungen von vorzüglicher Chlorechtheit liefert.In the further development of the process protected by patent 205377 was found that by condensation of nitroaceanthrenchinon with 3-oxy (i) thionaphten and subsequent partial reduction to obtain a dye which unheated cotton colors from the vat in full, genuine, chocolate-brown tones. This result was surprising because, on the one hand, the dye consists of aceanthrenequinone and 3-oxy (i) thionaphthene only provides weak and non-washable stains (cf. also Berl. Reports 44, p. 854). On the other hand, the corresponding condensation product from nitroacenaphthenequinone is not chlorine-resistant, while the dye obtainable by the present process is colorations of excellent chlorine fastness.
Das zur Kondensation angewandte Nitroaceanthrenchinon wird aus dem in den Berliner Berichten 44, S. 209 beschriebenen Aceanthrenchinon durch Nitrieren in konzentrierter schwefelsaurer Lösung mit der für ein Mononitroderivat berechneten Menge Mischsäure in der üblichen Weise erhalten und das Produkt ev. durch Umkristallisieren aus Eisessig gereinigt. Es ist darin ziemlich schwer löslich, kristallisiert daraus in glasigen Krusten und hat keinen scharfen Schmelzpunkt, indem es lange vor der Verflüssigung sintert und sich bräunt.The nitroaceanthrenequinone used for condensation becomes from the aceanthrenchinon described in the Berlin reports 44, p. 209 by nitrating in concentrated sulfuric acid solution with the amount of mixed acid calculated for a mononitro derivative obtained in the usual way and the product possibly by recrystallization from glacial acetic acid cleaned. It is rather difficult to dissolve in it and crystallizes from it in glassy crusts and does not have a sharp melting point by sintering and long before liquefaction tans.
6 Teile dieses Nitrokörpers werden in 500 Volumteilen Eisessig kochend gelöst und mit der äquivalenten Menge technischer 3-Oxy(i)thionaphten-2-karbonsäure, ebenfalls in Eisessig gelöst, versetzt. Zu der kochenden Lösung läßt man nach und nach 50 Volumteile konzentrierte Salzsäure fließen, wobei sich der Farbstoff als orangefarbener, kristallinischer Niederschlag rasch abscheidet. Er wird abfiltriert, gewaschen, mit Sprit zu einem Brei verrieben und nach Zusatz von Schwefelnatrium in geringem Überschuß auf dem Dampfbad erwärmt. Hierbei schlägt die orangebraune Farbe der Suspension in ein dunkles Schokoladebraun um. Nach dem Absaugen und Waschen liegt der Farbstoff in unmittelbar küpbarer Form vor. In konzentrierter Schwefelsäure ist er mit grüner Farbe löslich, mit Natronlauge und Hydrosulfit gibt er eine grünliche Küpe. Die Reduktion des •Nitrofarbstoffs geht unter obigen Bedingungen im wesentlichen nur bis zum Aminokörper.6 parts of this nitro body are dissolved in 500 parts by volume of glacial acetic acid and at the boil with the equivalent amount of technical 3-oxy (i) thionaphthene-2-carboxylic acid, also dissolved in glacial acetic acid, added. Gradually 50 parts by volume are added to the boiling solution concentrated hydrochloric acid flow, whereby the dye turns out to be orange, crystalline Precipitation separates quickly. It is filtered off, washed, with fuel to one Triturated into a pulp and, after adding sodium sulphide in a slight excess, on the Steam bath heated. The orange-brown color of the suspension changes to a dark chocolate brown. After suction and washing, the dye is in an immediately kneadable form. In concentrated Sulfuric acid is soluble with green color, with caustic soda and hydrosulfite there he a greenish vat. The reduction of the • nitro dye takes place under the above conditions essentially only up to the amino body.
