Description

  

      Verfahren    zur Darstellung eines als     Farbstoff    und     Farbstoffzwischenprodukt     verwendbaren     Kondensationsproduktes    der     Anthrachinonreihe.       Es wurde befunden, dass man ein neues,  als Farbstoff und     F.arbstoffzwischenprodukt     verwendbares Kondensationsprodukt der An  thrachinonreihe erhält, wenn man     Cyanur-          chlorid        und        l.-Amino-4-Methoxy-Anthrachino.n          miteinander    umsetzt.  



  <I>Beispiel:</I>  253 Teile     1--##@mino-4-Methoxy-Anthrachi-          non    werden mit 61,5 Teilen     Cyanurchlorid    in  Nitrobenzol erwärmt und während 10 Stun  den bei zirka. 100   gerührt.     Hierauf        wird        ent-          yvässertes        Natriumacetat    (200 Teile) zugege  ben und nach einer weitern Stunde die Tem  peratur auf 115 bis 120' gesteigert. Bei     :die-          ser    wird zirka     2.1    Stunden gehalten.

   Nach  dem     Erkalten    wird das ausgeschiedene Re  aktionsprodukt     abfiltriert    und mit     Nitroben-          zol    und darauf mit Alkohol gewaschen, bis  letzterer nicht mehr blaurot gefärbt erscheint.  Man erhält einen     ziegelfarbenen    Körper mit  je nach der Reaktionsdauer, sowie auch dem  angewandten Mengenverhältnis der Aus  gangsmaterialien     schwankendem    -Prozentsatz    an' Chlor.

   In trockenem Zustand stellt     das     neue Kondensationsprodukt ein     ziegelfar.-          benes    Pulver dar, das in Wasser unlöslich ist,  sich in kaltem und heissem Alkohol wenig mit  oranger Farbe, in heissem Chlorbenzol mässig,  noch etwas besser in heissem Nitrobenzol mit       rotoranger    Farbe, in kalter konzentrierter       Schwefelsäure    mit blutroter Farbe löst und,  aus der     bräunlichorangen        Küpe    auf Baum  wolle gefärbt, rotorange bis gelbrote Töne  liefert.



      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 anthrachinone series which can be used as dye and intermediate dye is obtained when cyanuric chloride and l-amino-4-methoxy-anthraquinone are reacted with one another.



  <I> Example: </I> 253 parts 1 - ## @ mino-4-methoxy-anthraquinone are heated with 61.5 parts of cyanuric chloride in nitrobenzene and heated for 10 hours at approx. 100 stirred. Dehydrated sodium acetate (200 parts) is then added and, after a further hour, the temperature is increased to 115 to 120 °. At: this is held for about 2.1 hours.

   After cooling, the precipitated reaction product is filtered off and washed with nitrobenzene and then with alcohol until the latter no longer appears blue-red. A brick-colored body is obtained with a percentage of 'chlorine which fluctuates depending on the duration of the reaction, as well as the ratio of the starting materials used.

   When dry, the new condensation product is a brick-colored powder that is insoluble in water, has a little orange color in cold and hot alcohol, moderately in hot chlorobenzene, even better in hot nitrobenzene with a red-orange color, in cold it is more concentrated Sulfuric acid dissolves with blood-red color and, dyed from the brownish-orange vat on cotton, delivers red-orange to yellow-red tones.
