Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 221928.         Yerfabren    zur Herstellung eines     Küpenfarbstoffs.       Gegenstand dieses Patentes ist     ein    Ver  fahren zur Herstellung eines neuen     Küpen-          farbstoffes    der     Anthrachinonreihe.    Das Ver  fahren ist dadurch     gekennzeichnet,        dass    man  das     Carbazol    aus     1-Amino-4-ss-naphthyl-          aminoanthrachinon    mit     o-Brombenzoylchlorid     umsetzt.

    werden in 300 Gewichtsteilen Nitrobenzol bei  160-170  unter Rühren so lange mit  kleinen Anteilen     @o-Brombenz.oylchlorid    ver  setzt, bis das Ausgangsmaterial verbraucht         Schwefelsäure    mit     grasgrüner,    in heissem       Pyridin    mit     oranger    Farbe. Er färbt Baum  wolle aus einer     orange    gefärbten     Küpe    in  etwas gedeckten rotorange Tönen.  



  <I>Beispiel:</I>  36     Gewichtsteile        3,4-Benzo-6-amino-7,8-          phthaloylearbazol    der     Formel       ist, wozu     etwa    22,5 Gewichtsteile dieses  Chlorids benötigt werden.

   Man     lässt        erkalten     und     gewinnt,den    Farbstoff in     dunkelbraunen     grossen Kristallen und in vorzüglicher Aus,           beute.    In geeigneter     Weise    (zum Beispiel aus       Chinolin    und verdünnter Salzsäure)     in.        Pa,sten-          form    .gebracht, lässt er sich     leicht    mit oranger  Farbe     verkiipen    und färbt aus dieser Lösung  Baumwolle in gedeckten rotorange Tönen von  sehr guten     Echtheiten    an.



  <B> Additional patent </B> to main patent no. 221928. Yerfabren for the production of a vat dye. The subject of this patent is a process for the production of a new vat dye of the anthraquinone series. The process is characterized in that the carbazole from 1-amino-4-ss-naphthylaminoanthraquinone is reacted with o-bromobenzoyl chloride.



  The dye dissolves in concentrated
EMI0001.0013
    are in 300 parts by weight of nitrobenzene at 160-170 with stirring with small proportions of @ o-bromobenz.oylchloride ver sets until the starting material consumes sulfuric acid with grass green, in hot pyridine with orange color. He dyes cotton from an orange vat in slightly muted red-orange tones.



  <I> Example: </I> 36 parts by weight of 3,4-benzo-6-amino-7,8-phthaloylearbazole of the formula, for which about 22.5 parts by weight of this chloride are required.

   It is allowed to cool and the dye is obtained in large, dark brown crystals and in excellent prey. In a suitable manner (for example from quinoline and dilute hydrochloric acid) in. Pa, stenform. Brought, it can easily be wrapped in orange and dyes cotton from this solution in muted red-orange shades of very good fastness properties.
