Description
Zusatzpatent zum Hauptpatent; Nr. <B>206728-</B> Verfahren zur Herstellung eines Farbstoffes der Anthrachinonreihe. Vorliegende Erfindung betrifft ein Ver fahren zur Herstellung eines neuen Küpen- farbstoffes der Anthrachinonreihe.
Das Verfahren ist dadurch gekennzeich net, dass man das Umsetzungsprodukt aus <B>1</B> Mol 1.5-Dibeiizoylamino-3.7-dihalogenan- thrachinon und<B>1</B> Mol 1-Aminoanthrachinon mit<B>1</B> Mol 1-Amino-5-benzoylainii)o-anthra- chinon umsetzt. Die Umsetzung führt man vorteilhaft in Gegenwart einer alkalischen Substanz wie Natriumkarbonat und zweck mässig in Gegenwart eines Kupfersalzes sowie eines hochsiedenden Lösungsmittels wie Ni- trobenzol durch.
Der neue Farbstoff stellt ein dunkelrotes Pulver dar, das sich in kon zentrierter Schwefelsäure zuerst mit schmutzig grüner Farbe löst.<B>-</B> Die Farbe schlägt bald in blau um. Der Farbstoff färbt aus rotbrau ner Küpe Baumwolle in kupferroten Tönen an. Die Färbungen sind hervorragend chlor- und lichtecht.
<I>Beispiel:</I> <B>15</B> Gewichtsteile 1.5-Di-benzoylamiiio- 3.7-dichloranthrachinon werden mit<B>7.5</B> Ge wichtsteilen 1-Aminoanthraebinon, <B>10</B> Ge wichtsteilen Natriumkarbonat,<B>0,3</B> Gewichts teilen Kupferacetat und<B>100</B> Gewichtsteilen Nitrobenzol 12 Stunden lang unter Rühren zum Sieden erhitzt. Der gebildete Farbstoff enthält noch einen austauschfähigen Chlor- substituenten. Er wird bei<B>500</B> abgesaugt, mit Nitrobenzol und Alkohol gewaschen und mit Wasser ausgekocht.
<B>10</B> Gewichtsteile des so erhaltenen Pro duktes werden mit<B>10</B> Gewichtsteilen 1-Amino- 5 <B>-</B> benzoylaminoanthrachinon, <B>10</B> Gewichts teilen Natriumkarbonat, 0,2 Gewichtsteilen Kupferacetat und<B>150</B> Gewichtsteilen Nitro- benzol 20 Stunden lang unter Rühren zum Sieden erhitzt. Der ausgeschiedene Farbstoff wird bei<B>500</B> abgesaugt, mit Nitrobenzol und Alkohol gewaschen und mit Wasser ausge- kocht. Er stellt ein dunkelrotes Pulver dar, welches sich in konzentrierter Schwefelsäure zuerst mit schmutzig grüner Farbe löst.
Die Farbe schlägt bald in blau tun. Der Farb stoff färbt aus rotbrauner Küpe Baumwolle ir) kupferroten Tönen an. Die Färbung ist vorzüglich chlor- und lichtecht.
Additional patent to main patent; No. <B> 206728- </B> Process for the preparation of a dye of the anthraquinone series. The present invention relates to a process for the production of a new vat dye of the anthraquinone series.
The process is characterized in that the reaction product of <B> 1 </B> mol of 1,5-dibeiizoylamino-3.7-dihalogenanthraquinone and <B> 1 </B> mol of 1-aminoanthraquinone with <B> 1 </ B> Mol 1-amino-5-benzoylainii) o-anthraquinone converts. The reaction is advantageously carried out in the presence of an alkaline substance such as sodium carbonate and expediently in the presence of a copper salt and a high-boiling solvent such as nitrobenzene.
The new dye is a dark red powder that first dissolves in concentrated sulfuric acid with a dirty green color. <B> - </B> The color soon turns blue. The dye stains cotton from the red-brown vat in copper-red tones. The dyeings are excellent chlorine and lightfast.
<I> Example: </I> <B> 15 </B> parts by weight of 1.5-di-benzoylamiiio- 3.7-dichloroanthraquinone with <B> 7.5 </B> parts by weight of 1-aminoanthraebinone, <B> 10 </ B > Parts by weight of sodium carbonate, <B> 0.3 </B> parts by weight of copper acetate and <B> 100 </B> parts by weight of nitrobenzene are heated to the boil for 12 hours while stirring. The dye formed still contains an exchangeable chlorine substituent. It is suctioned off at <B> 500 </B>, washed with nitrobenzene and alcohol and boiled with water.
<B> 10 </B> parts by weight of the product thus obtained are divided with <B> 10 </B> parts by weight of 1-amino-5 <B> - </B> benzoylaminoanthraquinone <B> 10 </B> weight Sodium carbonate, 0.2 part by weight of copper acetate and 150 parts by weight of nitrobenzene were heated to the boil for 20 hours while stirring. The separated dye is suctioned off at <B> 500 </B>, washed with nitrobenzene and alcohol and boiled with water. It is a dark red powder that first dissolves in concentrated sulfuric acid with a dirty green color.
The color soon beats doing in blue. The dye stains cotton ir) copper-red tones from the reddish brown vat. The coloring is excellent chlorine and lightfast.
