Description

  

      Verfahren    zur Darstellung eines     Küpenfarbstoües    der     Anthraehinonreihe.       Gegenstand des vorliegenden Zusatz  patentes ist ein Verfahren zur Darstellung  eines     Küpenfarbstoffes    der     Anthrachinon-          reihe,    welches dadurch gekennzeichnet ist,  dass man     4-Amino-2.1-anthrachinon-6'-chlor-          benzacridon    mit     m-co-Trifluormethylbenzoyl-          fluorid    umsetzt.  



  <I>Beispiel:</I>  50 Gewichtsteile     4-Amino-2.1-anthrachi-          non-6'-chlorbenzacridon    von der Formel:  
EMI0001.0013     
    erhältlich durch Kondensation von     1-Brom-          4    -     aminoanthrachinon    - 2 -     sulf        onsäure        mit    6-         Chloranthranilsäure,    werden in 600 Gewichts  teilen Nitrobenzol mit 100 Gewichtsteilen       m-w-Trifluormethylbenzoylfluorid    und etwa  1/2 Gewichtsteil     Pyridin    bei 198 bis 200   C  etwa 11/2 bis 2     Stunden    erhitzt,

   wobei die  grünblaue Lösung des     Aminoacridons    nach  Violett umschlägt. Nach dem Erkalten und  Absaugen erhält man den violett glänzenden  Farbstoff vom Schmelzpunkt 318   C     in    rei  ner kristallisierter Form. Er löst sich in  Schwefelsäure mit oranger Farbe und färbt  aus kräftiger violetter     Küpe    ein sehr schönes  klares Blau von guten Echtheitseigenschaften.



      Process for the preparation of a vat color of the anthraehinone series. The subject of the present additional patent is a process for the preparation of a vat dye of the anthraquinone series, which is characterized in that 4-amino-2,1-anthraquinone-6'-chlorobenzacridone is reacted with m-co-trifluoromethylbenzoyl fluoride.



  <I> Example: </I> 50 parts by weight of 4-amino-2.1-anthraquinone-6'-chlorobenzacridone of the formula:
EMI0001.0013
    obtainable by condensation of 1-bromo-4-aminoanthraquinone-2-sulfonic acid with 6-chloroanthranilic acid, are in 600 parts by weight of nitrobenzene with 100 parts by weight of mw trifluoromethylbenzoyl fluoride and about 1/2 part by weight of pyridine at 198 to 200 C about 11/2 to Heated for 2 hours,

   whereby the green-blue solution of the aminoacridone turns purple. After cooling and filtering off with suction, the shiny purple dye with a melting point of 318 ° C. is obtained in pure crystallized form. It dissolves in sulfuric acid with an orange color and turns a strong violet vat into a very beautiful clear blue with good fastness properties.
