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     1-Amino-4-methoxy-anthrachinon     und     4-Amino-2.1-Anthrachinonakridon    um  setzt.  



       Beispiel:     Eine Lösung von 18,5 Teilen     Cyanur-          chlorid    in etwa 300 Teilen     Nitrobenzol    wird  mit 34 Teilen 4     Amino-2.1-Anthrachinonakri-          don    während einer halben Stunde bei schwa  chem Sieden des     Nitrobenzols    erhalten, dar  nach wird erkalten gelassen und filtriert.  Das so erhaltene feste Produkt wird in etwa  300 Teilen, vorteilhaft etwa     0,8"/o        Diäthyl-          anilin    enthaltenden, Nitrobenzol aufgenommen.

    Nach Zusatz von 25,3 Teilen     1-Amino-4-          methoxy-anthrachinoi:    --     \,#lischung    wird diese  während 10 Stunden auf 100 , sodann nach  Zugabe von 20 Teilen     calcinierter    Soda wäh  rend dreissig Stunden auf     120-12511    erwärmt,  zweckmässig unter Rühren. Nach Erkalten    wird das ausgeschiedene neue Kondensations  produkt     abfiltriert,    gewaschen und getrocknet.  Es stellt ein blauschwarzes Pulver dar, ist  unlöslich in kaltem und heissem Wasser, sowie  Alkohol, sehr schwer löslich in kaltem Chlor  benzol und Nitrobenzol, schwer löslich in  siedendem Chlorbenzol, ziemlich löslich in  siedendem Nitrobenzol mit marineblauer Farbe.

    Seine Lösung in konzentrierter Schwefelsäure  ist braunrot. Es -liefert eine rote     Küpe,    aus  der Baumwolle in grauen Tönen angefärbt 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 dye and dye intermediate is obtained if cyanuric chloride is reacted with 1-amino-4-methoxy-anthraquinone and 4-amino-2,1-anthraquinone acridone.



       Example: A solution of 18.5 parts of cyanuric chloride in about 300 parts of nitrobenzene is obtained with 34 parts of 4-amino-2,1-anthraquinone acridone over half an hour with the nitrobenzene boiling gently, after which it is allowed to cool and filtered. The solid product thus obtained is taken up in about 300 parts, advantageously about 0.8 "/ o diethylaniline-containing nitrobenzene.

    After adding 25.3 parts of 1-amino-4-methoxy-anthraquinone: - \, # mixture this is heated to 100 for 10 hours, then after the addition of 20 parts of calcined soda for thirty hours to 120-12511, appropriate while stirring. After cooling, the precipitated new condensation product is filtered off, washed and dried. It is a blue-black powder, is insoluble in cold and hot water, as well as alcohol, very sparingly soluble in cold chlorobenzene and nitrobenzene, sparingly soluble in boiling chlorobenzene, fairly soluble in boiling nitrobenzene with a navy blue color.

    Its solution in concentrated sulfuric acid is brownish red. It delivers a red vat from which cotton is dyed in gray tones.
