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-          chlorid    und 1 -     5-Diamino-4.        8-Dioxyanthra-          chinon    miteinander umsetzt.  



       Beispiel:     30 Teile 1 .     5-Diainiilo-4                 8-Dioxy        anthra-          chinon,    18 Teile     Cyanurchlorid    werden unter       Zusatz    von etwas     Kupferchloriir        während     ca.     \?4    Stunden in     Nitrobenzol    auf 130 bis  <I>140</I>   erhitzt.

       Mjenn    die     Salzsäureentwick-          lung    nachgelassen hat, wird abkühlen gelas  sen und das ausgeschiedene Kondensations  produkt von der     Nitrobenzolmutterlauge    ge  trennt. Nach Reinigen und Trocknen stellt es       (ein    blauschwarzes Pulver dar, das unlöslich  in Wasser, wenig löslich in kaltem und hei  ssem Alkohol, mässig löslich in kaltem und  ziemlich gut löslich in heissem     Nitrobenzol     mit blauroter Farbe ist. Seine Lösung in kal  ter     konzentrierter        Schwefelsäure    ist violett,    seine     Küpe    bräunlich gefärbt; auf Baumwolle  lassen sich mit ihm blaue Töne erzielen.



  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 type which can be used as a dye and dye intermediate can be obtained. thrachinone series is obtained when cyanuric chloride and 1-5-diamino-4. 8-Dioxyanthraquinone reacts with one another.



       Example: 30 parts 1. 5-Diainiilo-4 8-Dioxy anthraquinone, 18 parts of cyanuric chloride are heated to 130 to 140 in nitrobenzene for about 4 hours with the addition of a little copper chloride.

       When the development of hydrochloric acid has subsided, it is allowed to cool and the precipitated condensation product is separated from the nitrobenzene mother liquor. After cleaning and drying, it is a blue-black powder that is insoluble in water, slightly soluble in cold and hot alcohol, moderately soluble in cold and fairly soluble in hot nitrobenzene with a bluish-red color. Its solution is in cold, concentrated sulfuric acid violet, its vat brownish in color; blue tones can be achieved with cotton
