Description
Zusatzpatent zum Hauptpatent Nr. 185420. Verfahren zur Darstellung eines Kondensationsproduktes der Anthraehinonreihe. Das vorliegende Verfahren betrifft die Darstellung eines Anthrachinonfarbstoffes und ist dadurch gekennzeichnet, dass man 1-Amino- 4-bromanthr#achinon-2-sulfonsäure mit 1-Me- thyl-4-aminobenzol-2-sulfomethyl-ätharrolamid kondensiert.
<I>Beispiel:</I> 10 Teile 1-amino-4-bromanthrachinon-2- sulfonsaures Natrium, 8 Teile 1-Methyl-4- aminobenzol-2-sulfomethyläthanolamid, 10 Teile Natriumbikarbonat, 0,4 Teile Kupfer pulver und 250 Teile Wasser werden in C02 Atmosphäre so lange bei 60 gerührt, bis die Umsetzung beendet ist.
Der erhaltene Farbstoff besitzt die Formel
EMI0001.0016
und färbt Wolle in blauen Tönen an.
Additional patent to the main patent No. 185420. Process for the preparation of a condensation product of the anthraehinone series. The present process relates to the preparation of an anthraquinone dye and is characterized in that 1-amino-4-bromanthralphinone-2-sulfonic acid is condensed with 1-methyl-4-aminobenzene-2-sulfomethyl-etharrolamide.
<I> Example: </I> 10 parts of 1-amino-4-bromoanthraquinone-2-sulfonic acid sodium, 8 parts of 1-methyl-4-aminobenzene-2-sulfomethylethanolamide, 10 parts of sodium bicarbonate, 0.4 part of copper powder and 250 Parts of water are stirred in a CO 2 atmosphere at 60 until the reaction has ended.
The dye obtained has the formula
EMI0001.0016
and dyes wool in blue tones.
