Description
Verfahren zur Darstellung eines sauren Wollfarbstoffes der Anthrachinonreihe. Gegenstand vorliegenden Zusatzpatentes ist ein Verfahren zur Darstellung eines sauren Wollfarbstoffes der Anthrachinon- reihe, das .darin besteht, dass, man 1 Mol Chinizarin mit 2 Mol 1-Amino-4-cyclohexyl- berrzol zur Umsetzung bringt und den so er haltenen Stoff sulfiert. <I>Beispiel:
</I> 10 Gewichtsteile Leukochinizarin, 20 Gewichtsteile Chinizarin und 15 Gewichts teile Borsäure werden mit 200 Gewichts teilen 1- Amino - 4 - cyclohexylbenzol unter Rühren auf 120 bis 130 erhitzt, bis die Schmelze eine klare grünstickig blaue Farbe angenommen hat. Darauf wird Luft eingelei tet und bei 7 0 mit 150 Gewichtsteilen Alko hol verdünnt. Das kristallin abgeschiedene Kondensationsprodukt wird abgesaugt, ge trocknet und aus Benzol umkristallisiert. Man erhält ein Produkt vom Schmelzpunkt <B>181</B> . Die Lösungsfarbe in konzentrierter Schwefelsäure ist rotstickig blau.
Der Farb stoff gibt nach der Sulfierung mit 5%igem Oleum bei Zimmertemperatur eine Disulfo- säure und färbt Wolle aus saurem Bade in grünen Tönen. Die Färbungen besitzen eine sehr gute Walk- und Waschechtheit. Das in dieser Reaktion verwendete Leukochinizarin dient dazu die Reaktion einzuleiten, und die verwendete Luft oxydiert etwa gebildete Leukoverbindungen.
Process for the preparation of an acidic wool dye of the anthraquinone series. The subject of the present additional patent is a process for the preparation of an acidic wool dye of the anthraquinone series, which consists in that 1 mole of quinizarine is reacted with 2 moles of 1-amino-4-cyclohexylberrzene and the substance thus obtained is sulfated. <I> example:
10 parts by weight of leucoquinizarine, 20 parts by weight of quinizarine and 15 parts by weight of boric acid are heated with 200 parts by weight of 1 - amino - 4 - cyclohexylbenzene to 120 to 130 while stirring until the melt has taken on a clear greenish blue color. Then air is introduced and diluted at 7 0 with 150 parts by weight of alcohol. The condensation product, which has separated out in crystalline form, is filtered off with suction, dried and recrystallized from benzene. A product with a melting point of <B> 181 </B> is obtained. The color of the solution in concentrated sulfuric acid is red and blue.
After sulphonation with 5% oleum, the dye gives a disulphonic acid at room temperature and dyes wool from an acid bath in green tones. The dyeings have very good mill and wash fastness. The leucoquinizarin used in this reaction is used to initiate the reaction, and the air used oxidizes any leuco compounds formed.
