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.

PATENTANSPRUCH: Verfahren zur Darstellung eines als Farbstoff und Farbstoffzwischenprodukt ver wendbaren Kondensationsproduktes der An thrachinon.reihe, darin bestehend, dass@ man Cyanurchlorid und 1-Aminoanthrachinon mit einander umsetzt, und zwar unter Anwen dung von weniger als drei Molekülen des letzteren auf je ein Molekül des ersteren. PATENT CLAIM: Process for the preparation of a condensation product of the anthrachinone series that can be used as a dye and dye intermediate, consisting in that cyanuric chloride and 1-aminoanthraquinone are reacted with one another, using less than three molecules of the latter per molecule of the former. Das neue Kondensationsprodukt ist ein .gelbes Pulver, 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 ziemlich gut mit grünlichgelber Farbe, in kalter konzen trierter Schwefelsäure mit rötlichgelber Farbe löst und in üblicher Weise mit Hydrosulfit und Natronlauge verküpt eine rotbraune Küpe liefert, aus welcher Baumwolle oder ZVolle in rein gelben Tönen .angefärbt wird. The new condensation product is a yellow powder that is insoluble in water, but only differs in cold and hot alcohol: very little, in cold chlorobenzene heavy, hot moderate, in nitrobenzene cold little, hot pretty good with a greenish yellow color, in cold more concentrated Sulfuric acid dissolves with a reddish-yellow color and is vat in the usual way with hydrosulphite and caustic soda gives a red-brown vat, from which cotton or whole is dyed in pure yellow shades.
