Description
Verfahren. zur Darstellung eines als Farbstoff und Farbstofizwischenprodukt verwendbaren Kondensationsproduktes der Anthrachinonreihe. Es wurde gefunden, dass man ein neues, als Farbstoff und Farbstoffzwischenprodukt verwendbares Kondensationsprodukt der An thra,chinonreihe erhält, wenn man Cyanur- chlorid und 1-Aminoanthra.chinon-6-sulfo- säure miteinander umsetzt.
<I>Beispiel:</I> 2 Teile 1-Aminoa_nthrachinon-6-sulfosäure werden unter Zusatz von 0,9 Teilen Natrium acetat in Form einer 10-prozentigen Lösung in 200 Teilen Wasser gelöst. Zu dieser Lö sung wird bei gewöhnlicher Temperatur unter Rühren eine Lösung von 1,4 Teilen Cy anur- chlorid in etwa 20 Teilen Aceton zugegeben. Darauf wird so lange weitergerührt, bis die rote Farbe der Aminosulfosäure verschwun den ist.
Alsdann werden weitere 2 Teile 1- Aminoanthr.achinon-6-sulfosäure und 0,9Teile Natriuma.cetat zugesetzt und die Lösung im Verlauf von mehreren Stunden bis zum be ginnenden Sieden erhitzt. Am S.chluss wird das Kondensationsprodukt durch Aussalzen in Form kleiner filziger, gelbgefärbter Nädel- chen gewonnen. Nach dem Trocknen stellt es ein orangegelbes Pulver dar, das sich in Wasser, verdünnter Natronlauge und ver dünnter Schwefelsäure mit gelber Farbe löst und Wolle aus saurem Bade in gelben Tönen anfärbt.
Procedure. for the preparation of a condensation product of the anthraquinone series which can be used as dye and dye intermediate. It has been found that a new condensation product of the anthracinone series which can be used as dye and dye intermediate is obtained if cyanuric chloride and 1-aminoanthraquinone-6-sulfonic acid are reacted with one another.
<I> Example: </I> 2 parts of 1-Aminoa_nthraquinone-6-sulfonic acid are dissolved in 200 parts of water with the addition of 0.9 parts of sodium acetate in the form of a 10 percent solution. A solution of 1.4 parts of cyanuric chloride in about 20 parts of acetone is added to this solution at ordinary temperature while stirring. Stirring is continued until the red color of the aminosulfonic acid has disappeared.
Then another 2 parts of 1-aminoanthr.achinone-6-sulfonic acid and 0.9 parts of sodium acetate are added and the solution is heated over the course of several hours to the start of boiling. At the end the condensation product is obtained by salting out in the form of small, felty, yellow-colored needles. After drying, it turns into an orange-yellow powder that dissolves in water, dilute sodium hydroxide solution and dilute sulfuric acid with a yellow color and dyes wool from an acid bath in yellow tones.
