Description
Verfahren zur Herstellung eines sauren Wollfarbstoffes. Vorliegendes Patent bezieht sich auf ein Verfahren zur Herstellung eines sauren Woll- farbstoffes, dadurch gekennzeichnet, dass man 1-Amino - 4 - bromanthrachinon - 2 -sulfonsäure mit m-Aminobenzyl-acetamid kondensiert und in dem erhaltenen Kondensationsprodukt die Acylgruppe durch Behandlung mit verseifen- den Mitteln abspaltet.
Der so erhaltene Farbstoff stellt ein dun kelblaues Pulver dar, das sich in konzentrier ter Schwefelsäure mit blaustichiggrüner Farbe löst, die auf Zusatz von Paraformaldehyd nach Gelbstichiggrün umschlägt, und färbt Wolle aus saurem Bade in klaren und sehr egalen rotstichig blauen Tönen von guter Lichtechtheit.
<I>Beispiel:</I> 40 Teile 1-Amino-4-bromanthrachinon-2- sulfonsäure werden in etwa 4000 Teilen Wasser gelöst und mit 50 Teilen des schwefel sauren Salzes des m-Amino-benzyl-acetamids, 84 Teilen Natriumbicarbonat und 4 Teilen Kupferchlorür versetzt. Die Lösung wird meh rere Stunden auf 90-95 C erhitzt. Ist die Farbstoff bildung beendet, so wird filtriert und der gebildete Farbstoff ausgesalzen.
Eine Suspension von 30 Teilen des obigen Farbstoffes und 800 Teilen Alkohol wird unter Einleiten von Ohlorwasserstoffgas etwa 8 Stunden zum Sieden erhitzt. Nachdem vor übergehend Lösung eingetreten ist, beginnt bald die Abscheidung des salzsauren Salzes des gebildeten neuen Farbstoffes, der keine Acylgruppe mehr enthält. Das Reaktionspro dukt wird heiss abgesaugt und mit Salzwasser von 15 B6 säurefrei gewaschen.
Es wird dann noch zweckmässig durch Aussahen aus sodaalkalischer wässeriger Lösung in das Natriumsalz übergeführt.
Process for the production of an acidic wool dye. The present patent relates to a process for the production of an acidic wool dye, characterized in that 1-amino-4-bromoanthraquinone-2-sulfonic acid is condensed with m-aminobenzyl-acetamide and the acyl group in the resulting condensation product is saponified splits off the means.
The dye thus obtained is a dark blue powder that dissolves in concentrated sulfuric acid with a bluish green color, which changes to yellowish green on addition of paraformaldehyde, and dyes wool from an acid bath in clear and very even reddish blue shades of good lightfastness.
<I> Example: </I> 40 parts of 1-amino-4-bromoanthraquinone-2-sulfonic acid are dissolved in about 4000 parts of water and mixed with 50 parts of the sulfuric acid salt of m-amino-benzyl-acetamide, 84 parts of sodium bicarbonate and 4 parts of copper chloride added. The solution is heated to 90-95 C for several hours. When the formation of the dye has ended, it is filtered and the dye formed is salted out.
A suspension of 30 parts of the above dye and 800 parts of alcohol is heated to boiling for about 8 hours while passing in hydrogen chloride gas. After a temporary solution has occurred, the deposition of the hydrochloric acid salt of the new dye that has formed, which no longer contains an acyl group, soon begins. The reaction product is filtered off with suction while hot and washed acid-free with salt water of 15 B6.
It is then expediently converted into the sodium salt by looking out from an aqueous solution of soda-alkali.
