Description
Verfahren zur Darstellung eines neuen Farbstoffes der Anthrachinonreihe. Das vorliegende Patent betrifft ein Ver fahren zur Darstellung eines neuen Farb stoffes der Anthrachinonreihe und ist da durch gekennzeichnet, dass man ein Gemisch aus 1,4-Oxyamino-6-chloranthrachinon und Leuko-1,4-Oxyamino-6-chloranthrachinon mit Mesidin kondensiert und die erhaltene Base sulfiert.
<I>Beispiel:</I> 12 Teile 1,4-Oxyamino-6-chloranthrachi- non, 17 Teile Leuko-1,4-oxyamino-6-chlor- a.nthrachinon, 75 Teile Mesidin, 25 Teile Eis essig und 10 Teile Borsäure werden unter Luftabschluss oder in inerter Atmosphäre so lange bei 80-110' gerührt, bis die Konden sation beendet ist. Die Schmelze wird in 500 Teilen Wasser und 100 Teilen konzentrierter Salzsäure eingerührt. Es wird kurze Zeit auf <B>80-90'</B> erwärmt und filtriert.
Die erhaltene Rohbase wird durch Oxydation und Kri stallisation aus organischen Lösungsmitteln, wie z. B. Anilin, gereinigt. Durch Sulfierung mit schwachem Oleum erhält man einen Farbstoff, der Wolle und Seide in grün stichig blauen Tönen von sehr guten Echt- heiten anfärbt. Der neue Farbstoff löst sich in Schwefelsäure mit blauer Farbe und hat folgende Formel:

Process for the preparation of a new dye of the anthraquinone series. The present patent relates to a process for the presentation of a new dye of the anthraquinone series and is characterized by the fact that a mixture of 1,4-oxyamino-6-chloranthraquinone and leuco-1,4-oxyamino-6-chloranthraquinone is condensed with mesidine and the base obtained is sulfated.
<I> Example: </I> 12 parts of 1,4-oxyamino-6-chloranthraquinone, 17 parts of leuco-1,4-oxyamino-6-chloro-a.nthraquinone, 75 parts of mesidine, 25 parts of glacial acetic acid and 10 parts of boric acid are stirred in the absence of air or in an inert atmosphere at 80-110 'until the condensation has ended. The melt is stirred into 500 parts of water and 100 parts of concentrated hydrochloric acid. It is heated to <B> 80-90 '</B> for a short time and filtered.
The crude base obtained is by oxidation and crystallization from organic solvents such. B. aniline, purified. Sulphonation with weak oleum gives a dye which dyes wool and silk in green, pungent blue shades with very good fastness properties. The new dye dissolves in sulfuric acid with a blue color and has the following formula:
