Description
Verfahren zur Darstellung eines sauren Farbstoffes der Anthr achinonr eihe. Gegenstand dieses Zusatzpatentes ist ein Verfahren zur Darstellung eines sauren Farb stoffes der Anthrachinonreihe, welches da durch gekennzeichnet ist, dass, man 1-amino- 4-bromanthrachinorr-2-sulfosaur,es Natrium mit 2-Aminotoluol-4-sulfonsäuremethylätha- nolamid kondensiert.
<I>Beispiel:</I> 40 Gewichtsteile 1-amino-4-brornarrthra- chinon-2-sulfosaures Natrium, 26 Gewichts teile 2-Amirrotoluol-4-sulfonsäuremethyl-ätha- nolamid, 20 C ewichtsteile Natriumbicarbonat, 3 Gewichtsteile gupferchlorür werden in 600 Gewichtsteilen Wasser bei<B>60-70'</B> C 24 Stunden gerührt. Nach Isolierung und Reinigung in der üblichen Weise wird ein Farbstoff erhalten, welcher auf Wolle und Seide ein klares Blau von sehr guter Egalität liefert.
Process for the preparation of an acidic dye of the anthracinone series. The subject of this additional patent is a process for the preparation of an acidic dye of the anthraquinone series, which is characterized in that 1-amino-4-bromoanthraquinor-2-sulfonic acid is condensed with sodium with 2-aminotoluene-4-sulfonic acid methylethanolamide.
<I> Example: </I> 40 parts by weight of 1-amino-4-brornarrthra- quinone-2-sulfonic acid sodium, 26 parts by weight of 2-amirrotoluene-4-sulfonic acid methyl-ethanolamide, 20 parts by weight of sodium bicarbonate, 3 parts by weight of gupferchlorur stirred in 600 parts by weight of water at 60-70 ° C. for 24 hours. After isolation and cleaning in the usual way, a dye is obtained which gives a clear blue of very good levelness on wool and silk.
