Description

  

  Verfahren zur Darstellung eines     güpenfarbstofPes    der     Anthrachinonreibe.       Gegenstand des vorliegenden Zusatz  patentes ist ein Verfahren zur Darstellung  eines     Küpenfarbstoffes    der     Anthrachinon-          reihe,    welches dadurch gekennzeichnet ist,  dass man     4-Amino-2.l-anthrachinon-6'-chlor-          benzacridon    mit     p-co-Trifluormethylbenzoyl-          fluorid    umsetzt.  



       Beispiel:     50 Gewichtsteile     4-Amino-2.        1-anthrachi-          non-6'-chlorbenzacridon    von der Formel  
EMI0001.0014     
    erhältlich durch Kondensation von 1-Brom-         4-aminoanthrachinon-2-sulfonsäure    mit     6-          Chloranthranilsäure,    werden in 600 Gewichts  teilen     Nitrobenzol    mit 100 Gewichtsteilen       p-a)-Trifluormethylbenzoylfluorid    und     etwa          1/2    Gewichtsteil     Pyridin    bei 190 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 393   C in rei  ner kristallisierter Form. Er löst sich in  Schwefelsäure mit oranger Farbe und färbt  aus kräftiger violetter     Küpe    ein sehr schö  nes klares Blau von guten Echtheitseigen  schaften.



  Process for the preparation of a quality dye of the anthraquinone grater. 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.l-anthraquinone-6'-chlorobenzacridone is reacted with p-co-trifluoromethylbenzoyl fluoride.



       Example: 50 parts by weight of 4-amino-2. 1-anthraquinone-6'-chlorobenzacridone of the formula
EMI0001.0014
    obtainable by condensation of 1-bromo-4-aminoanthraquinone-2-sulfonic acid with 6-chloranthranilic acid, in 600 parts by weight of nitrobenzene with 100 parts by weight of pa) trifluoromethylbenzoyl fluoride and about 1/2 part by weight of pyridine at 190 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 with suction, the shiny purple dye with a melting point of 393 ° 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.

PATENTANSPRUCH: Verfahren zur Darstellung eines Küpen- farbstoffes der Anthrachinonreihe, dadurch gekennzeichnet, dass man 4-Amino-2.1-an- thrachinon-6'-chlorbenzacridon mit p-co-Tri- fluormethylbenzoylfluorid umsetzt. Der so erhaltene Farbstoff bildet; violette Kristalle vom Schmelzpunkt 393 " C und färbt aus violetter Iiürpe ein schönes klares Blau von guten Echtheitseigenschaften. Claim: Process for the preparation of a vat dye of the anthraquinone series, characterized in that 4-amino-2.1-anthraquinone-6'-chlorobenzacridone is reacted with p-co-trifluoromethylbenzoyl fluoride. The dye thus obtained forms; violet crystals with a melting point of 393 "C and turns violet Iiürpe into a beautiful clear blue with good fastness properties. UNTERANSPRUCH: Verfahren nach Patentanspruch, dadurch gekennzeichnet, dass man die Reaktionskom- ponenten in Gegenwart von Nitrobenzol und etwas Pyridin erhitzt, bis kein Fluorwasser- stoff mehr entweicht. SUBSTANTIAL CLAIM: Process according to patent claim, characterized in that the reaction components are heated in the presence of nitrobenzene and a little pyridine until no more hydrogen fluoride escapes.
