Description
Zusatzpatent zum Hauptpatent Nr. 208546. Verfahren zur Herstellung eines Antbrachinonderivates. Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung eines neuen Wollfarbstoffes der Anthrachinonreihe, wel ches dadurch gekennzeichnet ist, dass man 4-p-Anisidino-4'-methylamino-l. l'-dianthra- chinonylamin mit 30 %igem Oleum bei einer Temperatur von 550 bis<B>600</B> ungefähr eine halbe Stunde behandelt.
Die so erhaltene Sulfosäure färbt Wolle in grüngrauen Tönen an. Der Farbstoff zeichnet sich durch ein gutes Egalisierungsvermögen aus.
<I>Beispiel:</I> <B>8</B> Gewichtsteile 4-p-Anisidino-4#-methyl- amino <B>- 1. l'-</B> dianthrachinonylamin (erhältlich aus 1-Methylamino-4-bromanthrachinon und 1-Amino-4-p-anisidinoantbrachinon durch An- thrimidschmelze) werden in der zehnfachen Gewichtsmenge 30"/oigem Oleums gelöst und bei<B>50</B> bis<B>60 0 0</B> 1/2 Stunde verrührt. Die Sulfonsäure färbt Wolle in grüngrauen Tönen an. Der Farbstoff zeichnet sich durch ein gutes Egalisierungsvermögen aus.
Additional patent to main patent no. 208546. Process for the production of an antbrachinone derivative. The present patent is a process for the preparation of a new wool dye of the anthraquinone series, wel Ches is characterized in that one 4-p-anisidino-4'-methylamino-l. Treated l'-dianthraquinonylamine with 30% oleum at a temperature of 550 to <B> 600 </B> for about half an hour.
The sulfonic acid obtained in this way stains wool in green-gray tones. The dye is distinguished by its good leveling capacity.
<I> Example: </I> <B> 8 </B> parts by weight of 4-p-anisidino-4 # -methyl- amino <B> - 1. l'- </B> dianthraquinonylamine (obtainable from 1-methylamino -4-bromoanthraquinone and 1-amino-4-p-anisidinoantbrachinone by anthrimide melt) are dissolved in ten times the amount by weight of 30% oleum and at <B> 50 </B> to <B> 60 0 0 </ B Stirred for> 1/2 hour. The sulfonic acid dyes wool in green-gray tones. The dye is characterized by good leveling properties.
