Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 221928.    Verfahren zur Herstellung eines     Nüpenfarbstoffes.       Gegenstand dieses     Patentes    ist ein Ver  fahren zur Herstellung eines neuen     Küpen-          farbatoffes    der     Anthrachinonreihe.    Das Ver  fahren ist dadurch gekennzeichnet, dass man  das     Carbazol    aus 1-     Amino    - 5 - (p -     Chlor-          phenyl)-aminoanthrachinon    der nachstehen  den     Formel     
EMI0001.0011     
    mit     o-Chlorbenzoylchlorid    umsetzt.  



  Der Farbstoff löst sich in konzentrierter  Schwefelsäure mit     tiefblauar,    in     heissem          Pyridin    mit     orangegelber    Farbe. Er färbt    Baumwolle aus seiner klaren braunorangen       Küpe    in klaren gelbbraunen Tönen.  



  <I>Beispiel:</I>  Teile.     3--Chlor-3'-amino-7,8-phthaloyl-          carbazol    der     nachstehenden    Formel  
EMI0001.0021     
    werden in 60 Teilen Nitrobenzol bei 150  ver  rührt und in etwa 20     Minuten    eine Lösung  von 3 Teilen     -o-Chlorbenzoylchlorid    in 10  Teilen Nitrobenzol eingerührt. Man     steigert     die Temperatur nach     1/2        Stunde    kurz auf 180       und lässt erkalten. Man erhält nach dem Ab  saugen, Auswaschen und Trocknen 6,3 Teile  eines gut     kristallisierten    Farbstoffes.

   In     kon-          zentrierter    Schwefelsäure löst er sich mit tief  blauer Farbe. Aus dieser Lösung fallen mit       Wasser        orangegelbe    Flocken.  



       In        Pyridin        löst        er        sich        ebenfalls     Er     liefert    mit Natronlauge und     Hydro-          sulfiteine    braunorange     Küpe,    aus der Baum  wolle in klaren und echten gelbbraunen  Tönen     gefärbt    wird.



  <B> Additional patent </B> to main patent no. 221928. Process for the production of a pebble dye. The subject of this patent is a process for the production of a new vat colorant of the anthraquinone series. The process is characterized in that the carbazole from 1-amino-5 - (p-chlorophenyl) -aminoanthraquinone of the formula below
EMI0001.0011
    reacts with o-chlorobenzoyl chloride.



  The dye dissolves in concentrated sulfuric acid with a deep blue color, in hot pyridine with an orange-yellow color. He dyes cotton from his clear brown-orange vat in clear yellow-brown tones.



  <I> Example: </I> parts. 3 - chloro-3'-amino-7,8-phthaloyl-carbazole of the formula below
EMI0001.0021
    are stirred in 60 parts of nitrobenzene at 150 and stirred in a solution of 3 parts -o-chlorobenzoyl chloride in 10 parts of nitrobenzene in about 20 minutes. The temperature is raised briefly to 180 after 1/2 hour and allowed to cool. After sucking off, washing out and drying, 6.3 parts of a well-crystallized dye are obtained.

   In concentrated sulfuric acid it dissolves with a deep blue color. Orange-yellow flakes fall from this solution with water.



       It also dissolves in pyridine. With caustic soda and hydrosulfite, it delivers a brown-orange vat from which cotton is dyed in clear, genuine yellow-brown tones.
