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    mit     2-Amino-anthrachinon    und     4-          Amino-2.        1-anthrachinonal-.ridon    umsetzt.  



  <I>Beispiel:</I>  <B>18,5</B> Teile in etwa 230 Teilen Nitrobenzol  gelösten     Cyanurchlorids    werden mit<B>23</B> Teilen       2-Amino-aiithrachinon,    vorzugsweise unter  Rühren, während einer halben Stunde auf  ungefähr 2000 erwärmt. Nach     Wiederab-          kühlen    wird filtriert und das auf dem Filter  zurückbleibende feste Produkt mit etwa<B>300</B>  Teilen frischem     Nitrobeijzol    vermischt. Die  Mischung wird mit 34 Teilen     4-Amiiio-2.1-          anthrachinonakridon    versetzt und darauf unter  Rühren während rund drei Stunden bei schwa  chem Sieden des Nitrobenzols gehalten.

   Nach  Erkalten wird das ausgeschiedene neue Kon  densationsprodukt     abfiltriert,    gewaschen und  getrocknet. Es stellt ein blaues Pulver dar,  ist unlöslich in kaltem und siedendem Wasser,  sowie Alkohol, sehr schwer löslich in kaltem    Chlorbenzol und Nitrobenzol, schwer löslich  in siedendem Chlorbenzol     und    Nitrobenzol mit  grünblauer Farbe. Seine Lösung in konzen  trierter Schwefelsäure ist braun. Es liefert  eine braunrote     Küpe,    aus der Baumwolle in  blaugrünen Tönen angefärbt wird.



  Process for the preparation of a condensation product of the anthraquinone series which can be used as a dye and intermediate dye. It has been found that a new condensation product of the anthraquinone series which can be used as dye and dye intermediate is obtained if cyanuric chloride is used with 2-amino-anthraquinone and 4-amino-2. 1-anthraquinonal .ridone converts.



  <I> Example: </I> <B> 18.5 </B> parts of cyanuric chloride dissolved in about 230 parts of nitrobenzene are mixed with <B> 23 </B> parts of 2-amino-aiithraquinone, preferably with stirring, during one Heated to about 2000 for half an hour. After cooling again, it is filtered and the solid product remaining on the filter is mixed with about 300 parts of fresh nitrobeijzene. 34 parts of 4-amino-2,1-anthraquinone acridone are added to the mixture and the nitrobenzene is then kept under stirring for about three hours.

   After cooling, the new condensation product which has separated out is filtered off, washed and dried. It is a blue powder, is insoluble in cold and boiling water and alcohol, very sparingly soluble in cold chlorobenzene and nitrobenzene, sparingly soluble in boiling chlorobenzene and nitrobenzene with a green-blue color. Its solution in concentrated sulfuric acid is brown. It delivers a brown-red vat from which cotton is dyed in blue-green tones.
