  Z<B>usatzpatent</B> zum Hauptpatent Nr. 97059.    Verführen zur Darstellung eines als     Farbstoff    und     Farbstoffzwischenprodukt    verwend  baren Kondensationsproduktes der     Anthrachinonreihe.       Es wurde gefunden, dass man ein neues,  als Farbstoff und     Farhstoffzwischenproclulct     verwendbares     Kondensationsprodukt        der        An-          thraehinonreihe    erhält, wenn man     Cyanur-          chlorid    und     5-Amino-2,1-anthrachinonakridon     miteinander umsetzt, und zwar unter An  wendung von weniger als drei, vorzugsweise  zwei,

   Molekülen des letzteren auf je ein Mo  lekül des ersteren.  



  <I>Beispiel</I>  34 Teile     5-Amino-2,1-anthracliinonakridoii     werden in 800 Teile Nitrobenzol     eingetragen     und mit 9,3 Teilen     Cyanurchlorid    versetzt.  Hierauf wird unter Rühren allmählich auf  <B>190</B> bis 200   erwärmt und einige Stunden  hei dieser Temperatur weitergerührt. Die  abgekühlte     Reaktionsflüssigkeit    wird fil  triert, der Rückstand mit     Nitrobenzol    und  mit Alkohol gewaschen und getrocknet.

    Das neue Kondensationsprodukt bildet ein  dunkelviolettes Pulver, löst sich in konzen  trierter Schwefelsäure mit rotorangen Farbe    und gibt mit     Hydrosulfit    und Natronlauge eine       violettbraune        Küpe,    aus welcher Baumwolle  hervorragend licht-, wasch- und chlorecht       hraunstichig    Kordeaux gefärbt     wird.  



  Z <B> additional patent </B> to main patent no. 97059. Seduction to present a condensation product of the anthraquinone series that can be used as a dye and dye intermediate. It has been found that a new condensation product of the anthraehinone series which can be used as a dye and intermediate dye is obtained if cyanuric chloride and 5-amino-2,1-anthraquinone acridone are reacted with one another, using fewer than three, preferably two,

   Molecules of the latter on each one Molecule of the former.



  <I> Example </I> 34 parts of 5-amino-2,1-anthracliinonakridoii are introduced into 800 parts of nitrobenzene, and 9.3 parts of cyanuric chloride are added. The mixture is then gradually heated to 190 to 200 while stirring and stirring is continued at this temperature for a few hours. The cooled reaction liquid is filtered off, the residue is washed with nitrobenzene and with alcohol and dried.

    The new condensation product forms a dark violet powder, dissolves in concentrated sulfuric acid with a red-orange color and, with hydrosulfite and sodium hydroxide solution, gives a violet-brown vat from which cotton is dyed with an excellent light, wash and chlorine-resistant corduroy.

PATENT ANSPRUCH: Verfahren zur Darstellung eines als Farb stoff und Farhstoffzwischenprodukt verwend- baren Kondensationsproduktes der Anthra- chinonreihe, dadurch gekennzeichnet, dass man Cyanurchlorid und 5-Amino-2,1-anthrachinon- akridon miteinander umsetzt, und zwar unter Anwendung von weniger als drei Molekülen des letzteren auf je ein Molekül des ersteren. PATENT CLAIM: Process for the preparation of a condensation product of the anthrachinone series which can be used as a dye and dye intermediate, characterized in that cyanuric chloride and 5-amino-2,1-anthraquinone acridone are reacted with one another using fewer than three Molecules of the latter to one molecule of the former. Das neue Kondensationsprodukt bildet ein dunkelviolettes Pulver, löst sich in konzen trierter Schwefelsäure mit rotorangen Farbe und gibt mit Hydrosulfit und Natronlauge eine violettbraune Küpe, aus welcher Baumwolle hervorragend licht-, wasch- und chlorecht hraunstichig Kordeaux gefärbt wird.
