Description
Verfahren zur Darstellung eines grünen Wollfarbstoffes der Anthrachinonreihe. Es wurde gefunden; dass sich wertvolle Wollfarbstoffe der Anthrachinonreihe dadurch herstellen lassen, dass man Chinizarin-6-sulfo- säure mit p-Aminoformaryliden oder p-Amino- aeetaryliden bezw. Substitutionsprodukten dieser .Körper zur Umsetzung bringt.
Die Re aktion kann in der für den Ersatz von Ogy- gruppen durch Aminreste üblichen Weise, zum Beispiel durch Kondensation der Chini- zarin-6-sulfosäure mit den genannten Aryliden in Gegenwart oder Abwesenheit von geeig neten Lösungsmitteln, insbesondere Eisessig, durchgeführt werden. Man erhält auf diese Weise grüne Farbstoffe, deren Ausfärbungen auf Wolle sehr gute Echtheitseigenschaften aufweisen. Gegenüber ähnlich gebauten be kannten Farbstoffen haben die neuen Pro dukte den Vorteil, ein erheblich besseres Egalisierungsvermögen zu besitzen.
Gegenstand vorliegender Erfindung ist nun ein Verfahren zur Darstellung eines grünen Wollfarbstoffes der Anthrachinonreihe, da durch gekennzeichnet, dass man Chinizarin-6- sulfosäure mit p-Amidoacetanilid kondensiert. <I>Beispiel:</I> 10 Gewichtsteile Chinizarin-6-sulfosäure, 30 Gewichtsteile p-Amidoacetanilid, 10 Ge wichtsteile Borsäure und 1 Gewichtsteil Zinkstaub werden in 100 Gewichtsteilen Eis essig angerührt und auf 100-110 0 erwärmt. Nach ca. 3-4 Stunden ist die Umsetzung beendet.
Man giesst die Schmelze in 1000 Gewichtsteile Wasser, fügt unter gutem Rüh ren 200 -Gewichtsteile Natronlauge 30 0 B6 zu und filtriert die abgeschiedenen grünen Nadeln ab. Man wäscht mit kaltem Wasser bis zum klaren Ablauf. Den Farbstoff kann man aus 5 % igem Pyridinwasser umlösen. Er ist in Wasser gelbstickig grün löslich und färbt auf Wolle aus saurem Bade ein gut egalisierendes gelbstickiges Grün.
Process for the preparation of a green wool dye of the anthraquinone series. It was found; that valuable wool dyes of the anthraquinone series can be produced by quinizarine-6-sulfonic acid with p-aminoformarylides or p-amino aeetarylides or. Substitution products of this body to implement.
The reaction can be carried out in the manner customary for replacing Ogy groups with amine residues, for example by condensing quinizarin-6-sulfonic acid with the arylides mentioned in the presence or absence of suitable solvents, in particular glacial acetic acid. In this way, green dyes are obtained, the dyeings of which on wool have very good fastness properties. Compared to known dyes of similar construction, the new products have the advantage of having a considerably better leveling capacity.
The present invention now relates to a process for the preparation of a green wool dye of the anthraquinone series, characterized in that quinizarine-6-sulfonic acid is condensed with p-amidoacetanilide. <I> Example: </I> 10 parts by weight of quinizarine-6-sulfonic acid, 30 parts by weight of p-amidoacetanilide, 10 parts by weight of boric acid and 1 part by weight of zinc dust are mixed in 100 parts by weight of glacial acetic acid and heated to 100-110 °. The reaction has ended after about 3-4 hours.
The melt is poured into 1000 parts by weight of water, 200 parts by weight of sodium hydroxide solution 30 0 B6 are added with thorough stirring and the green needles that have separated out are filtered off. Wash with cold water until the drain is clear. The dye can be redissolved from 5% pyridine water. It is soluble in water to give a yellowish green solution and dyes wool from an acidic bath a well-equalizing yellowish green.
