Description

  

      Zusatzpatent    zum Hauptpatent Nr. 97059.    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       Anthrachinonreihe    erhält, wenn man 1     Mol.          Cyanurchlorid    mit 1     Mol.        4-Amino-2,1-an-          thrachinonakridon    und 1     Mol.        5-Amino-2,

  1-          anthrachinonakridon    umsetzt.    <I>Beispiel:</I>  9,3 Teile     Cyanurchlorid    und 17 Teile     4-          Amino-2,1-anthrachinonakridon    werden in  500 Teile     Nitrobenzol    eingetragen und die  Mischung einige Zeit bei     100-120'    gerührt.  Hierauf versetzt man mit 17 Teilen 5  Amino-2,1-anthrachinonakridon und kocht'  einige Zeit am     Rückflusskühler.    Die abge  kühlte     Reaktionsflüssigkeit    wird hierauf fil  triert, der Rückstand mit Nitrobenzol und  mit Alkohol gewaschen und getrocknet.

   Das  neue Kondensationsprodukt bildet ein dunkles  Pulver, es löst sich in konzentrierter Schwe  felsäure mit rotorangen Farbe und gibt mit         Hydrosulfit    und Natronlauge eine stumpf       rotviolette        Küpe,    aus welcher Baumwolle in  echten     violettgrauen    Tönen gefärbt wird.



      Additional patent to main patent No. 97059. 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 a dye and intermediate dye is obtained if 1 mole of cyanuric chloride is mixed with 1 mole of 4-amino-2,1-anthraquinone acridone and 1 mole of 5-amino-2 ,

  1- anthraquinone acridone converts. <I> Example: </I> 9.3 parts of cyanuric chloride and 17 parts of 4-amino-2,1-anthraquinone acridone are introduced into 500 parts of nitrobenzene and the mixture is stirred for some time at 100-120 '. 17 parts of 5-amino-2,1-anthraquinone acridone are then added and the mixture is boiled on a reflux condenser for some time. The cooled reaction liquid is then filtered, the residue washed with nitrobenzene and with alcohol and dried.

   The new condensation product forms a dark powder, it dissolves in concentrated sulfuric acid with a red-orange color and, with hydrosulfite and caustic soda, gives a dull red-violet vat from which cotton is dyed in real violet-gray tones.
