Description

  

  Verfahren zur Darstellung eines     Küpenfarbstoffes    der     Anthrachinonreihe.       Es wurde     gefunden,    dass man einen neuen       Küpenfarbstoff    der     Anthrachinonreihe    erhält,       wein    man     5.5'-Dibenzoylamirro-1.1'-dianthri-          mid    mit konzentrierter Schwefelsäure behan  delt und das so erhaltene Zwischenprodukt  zum Farbstoff oxydiert.

      <I>Beispiel:</I>    Ein Gewichtsteil     5.5'-Dibenzoylarrrirro-1.1'-          dianthrimid    wird in 10 Gewichtsteilen Schwe  felsäure<B>660</B>     B6        suspensiert    und bei 30 bis       350    C so lange gerührt, bis die Masse eine  olive Farbe angenommen hat. Darauf wird  das so erhaltene Zwischenprodukt zum Bei  spiel mit 10 Gewichtsteilen von 40 >     igem          Oleum    zum     Farbstoff    oxydiert und die Reak  tionsmischung auf Eis     gegossen.-    Der Farb  stoff scheidet sich in Form gelber     Flocken     ab.

   Er wird     abfiltriert,    in Wasser gewaschen  und getrocknet. Der neue     Farbstoff    stellt ein  oranges Pulver dar, das in konzentrierter  Schwefelsäure mit blauer Farbe löslich ist  und sich in kochendem     Chinolin    mit gelber  Farbe schwer löst. Es bildet mit Alkali-         hydrosulfitlöaungen    eine rotgelbe     Küpe,    aus  der Baumwolle in leuchtenden,     gelborange-          nen,    licht- und waschechten Nuancen gefärbt  wird.



  Process for the preparation of a vat dye of the anthraquinone series. It was found that a new vat dye of the anthraquinone series is obtained when 5.5'-dibenzoylamirro-1.1'-dianthrimide is treated with concentrated sulfuric acid and the intermediate product thus obtained is oxidized to the dye.

      <I> Example: </I> One part by weight of 5.5'-dibenzoylarrirro-1.1'-dianthrimide is suspended in 10 parts by weight of sulfuric acid <B> 660 </B> B6 and stirred at 30 to 350 C until the mass has a has assumed olive color. The intermediate product thus obtained is then oxidized to the dye with 10 parts by weight of 40> oleum oleum, for example, and the reaction mixture is poured onto ice. The dye separates out in the form of yellow flakes.

   It is filtered off, washed in water and dried. The new dye is an orange powder that is soluble in concentrated sulfuric acid with a blue color and difficult to dissolve in boiling quinoline with a yellow color. Together with alkali hydrosulfite solutions, it forms a red-yellow vat from which cotton is dyed in bright, yellow-orange, lightfast and washfast shades.

PATENTANSPRUCH: Verfahren zur Darstellung eines neuen Küpenfarbstoffes der Anthrachinonreihe, da durch gekennzeichnet, dass man 5.5'-Diben- zoylamino-1.1'-dianthrimid 'mit konzentrierter .Schwefelsäure behandelt und das so erhält liche Zwischenprodukt zum Farbstoff oxydiert. PATENT CLAIM: Process for the preparation of a new vat dye of the anthraquinone series, characterized in that 5.5'-dibenzoylamino-1.1'-dianthrimide 'is treated with concentrated sulfuric acid and the intermediate product thus obtained is oxidized to the dye. Der neue Farbstoff stellt ein gelbes Pulver dar, das in konzentrierter Schwefelsäure mit blauer Farbe löslich ist, sich in siedendem Chinolin schwer mit gelber Farbe löst und mit Alkalihydr-osulfitlösungen eine rotgelbe Küpe gibt, aus der Baumwolle in leuchtenden, gelborangenen, licht- und waschechten Nuan cen gefärbt wird. The new dye is a yellow powder that is soluble in concentrated sulfuric acid with a blue color, is difficult to dissolve in boiling quinoline with a yellow color and with alkali hydride sulfite solutions gives a red-yellow vat, from which cotton comes in bright, yellow-orange, light- and washfast Nuan cen is colored.
