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.
