Description
Verfahren zur Darstellung eines als Farbstoff und Farbstoffzwischenprodukt verwendbaren Kondensationsproduktes der Anthrachinonreihe. Es wurde gefunden, dass man ein neues, als Farbstoff und Farbstoffzwischenprodukt verwendbares Kondensationsprodukt der An- thrachinonreihe erhält, wenn man Cyanur- clilorid und 1-Aininoanthrachinon miteinan der umsetzt, und zwar unter Anwendung von weniger .als drei, vorzugsweise zwei Mole külen des letzteren auf je ein Molekül .des ersteren.
<I>Beispiel:</I> 92.2 Teile Cyanurchlorid werden in zirka, 2000 Teilen Nitrobenzol gelöst und mit 223 Teilen 1-Aminoauthrachinon, vorteilhaft un ter Rühren, während einer halben Stunde auf 190 bis 1.95 erhitzt. Das unter Salzsäure- entwicl@liing entsi:ehende neue Kondensations produkt wird durch Abfiltrieren des Nitro benzols gewonnen und wenn nötig noch ge reinigt.
Getrocknet stellt es ein chlorhaltiges gelbes Pulver dar, das in Wasser unlöslich ist, sich in kaltem und heissem Alkohol nur ganz wenig, in Chlorbenzol kalt schwer, heiss mässig, in Nitrobenzol kalt wenig, heiss ziem lich gut mit griinlich.gelber Farbe, in kalter konzentrierter Schwefelsäure mit rötlichgel- ber Farbe löst und in üblicher Weise mit Ilydrosulfit und Natronlauge verküpt eine rotbraune Küpe liefert, aus welcher Baum wolle oder Wolle in rein gelben Tönen ange färbt wird.
Process 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 anthraquinone series which can be used as a dye and dye intermediate is obtained if cyanuric chloride and 1-aininoanthraquinone are reacted with one another using less than three, preferably two, molecules of the latter on one molecule each of the former.
<I> Example: </I> 92.2 parts of cyanuric chloride are dissolved in approximately 2000 parts of nitrobenzene and heated with 223 parts of 1-aminoauthraquinone, advantageously with stirring, to 190 to 1.95 for half an hour. The new condensation product resulting from the development of hydrochloric acid is obtained by filtering off the nitrobenzene and, if necessary, purified.
When dried, it is a yellow powder containing chlorine, which is insoluble in water, differs very little in cold and hot alcohol, heavy in cold chlorobenzene, moderate in hot, little in cold nitrobenzene, fairly good in hot with a greenish yellow color, in cold concentrated sulfuric acid dissolves with a reddish yellow color and, in the customary manner, vat with ilydrosulfite and sodium hydroxide solution delivers a red-brown vat from which cotton or wool is dyed in pure yellow tones.
