Zusatz zum Patente 198025 vom 23. Juni 1907.Addendum to the 198025 patent dated June 23, 1907.
Patentiert im Deutschen Reiche vom 21. September 1907 ab. Längste Dauer: 22. Juni 1922.Patented in the German Empire on September 21, 1907. Longest duration: June 22, 1922.
In dem Patent 198025 ist u. a. gezeigt worden, daß das aus Dinitrodianthraehinonylamin durch Reduktion erhältliche Diaminodianthrachinonylamin bei der Behandlung mit S Essigsäureanhydrid oder Eisessig in Gegenwart von konzentrierter oder rauchender Schwefelsäure einen Farbstoff liefert, welcher Baumwolle in der Hydrosulfitküpe in klaren blauen Tönen anfärbt.In the 198025 patent, inter alia. has been shown to be derived from dinitrodianthraehinonylamine Diaminodianthraquinonylamine obtainable by reduction on treatment with S acetic anhydride or glacial acetic acid in the presence of concentrated or fuming sulfuric acid provides a dye which Dyes cotton in the hydrosulfite vat in clear blue tones.
Es wurde nun gefunden, daß man an Stelle der genannten Diamino- auch die Dinitroverbindung verwenden kann, indem man sie mit rauchender Schwefelsäure und Schwefel in Gegenwart von Eisessig oder Essigsäureanhydrid behandelt.It has now been found that the dinitro compound can also be used instead of the diamino compound mentioned can use by treating them with fuming sulfuric acid and sulfur treated in the presence of glacial acetic acid or acetic anhydride.
10 Teile des im Patent 186465 beschriebenen Dinitrodianthrachinonylamins werden bei 20 bis 25 ° in eine Lösung von 2 Teilen Schwefel in 100 Teilen rauchender Schwefelsäure von 23 Prozent S O3- Gehalt eingetragen. Hierauf läßt man unter Rühren bei 20 bis 25 ° 10 Teile Essigsäureanhydrid zutropfen und hält die Temperatur während 8 bis 10 Stunden auf etwa 300. Die Schmelze wird in Wasser gegossen, der Farbstoff abfiltriert und neutral gewaschen.10 parts of the dinitrodianthraquinonylamine described in patent 186465 are introduced at 20 to 25 ° into a solution of 2 parts of sulfur in 100 parts of fuming sulfuric acid with a 23 percent SO 3 content. Thereto is allowed under stirring at 20 to 25 ° 10 parts of acetic anhydride are added dropwise, keeping the temperature for 8 to 10 hours to about 30 0th The melt is poured into water, the dye is filtered off and washed neutral.
. IO Teile Dinitrodianthrachinonylamin (Patent 186465) werden in eine Lösung von 2 Teilen Schwefel in 100 Teilen rauchender Schwefelsäure von 45 Prozent 5 O3-Gehalt eingetragen und hierauf mit 10 Teilen Eisessig bei 25 bis 300 bis zur vollendeten Farbstoffbildung behandelt. Die weitere Aufarbeitung des Reaktionsgemisches ist dieselbe wie in Beispiel 1.. IO parts Dinitrodianthrachinonylamin (Patent 186465) are added to a solution of 2 parts of sulfur in 100 parts of fuming sulfuric acid of 45 percent 5 O 3 content and then treated with 10 parts of glacial acetic acid at 25 to 30 0 to the completed dye formation. The further work-up of the reaction mixture is the same as in Example 1.
Der Farbstoff zeigt die gleichen Reaktionen wie das in Beispiel 1 des Patentes 198025 beschriebene Produkt.The dye shows the same reactions as that in Example 1 of the 198025 patent described product.
