  Zusatzpatent zum Hauptpatent Nr. 194458.    Verfahren zur Herstellung eines     güpenfarbstoifes.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung eines     Küpenfarb-          stoffes,    dadurch     gekennzeichnet,    dass man         5,5'-Diamino-diphthaloylcarbazol        mit        Bz1-          Brombenzanthron    kondensiert und das Kon  densationsprodukt der Formel:

      ein alkalisches Kondensationsmittel und     An-          thrachinon-2-carlionsäurechlorid    aufeinander  einwirken lässt.  



  Der neue     Küpenfarbstoff    löst sich in kon  zentrierter Schwefelsäure mit     blaustichig-          grüner    Farbe und färbt die pflanzliche Faser  aus brauner     Küpe    in sehr echten     Khakitönen.       <I>Beispiel 1:</I>  45 Teile     5,5'-Diamino-diphthaloylearbazol     werden mit 31 Teilen     Bzl-Brombenzanthron     kondensiert und dieses Kondensationsprodukt  mit alkoholischem Kali verschmolzen. (Das  erhaltene Produkt löst sich in konzentrierter  Schwefelsäure mit olivgrüner Farbe.

   Aus  konzentrierter     Schwefelsäure    umgelöst; färbt  es aus brauner     Küpe    Baumwolle in dunkel  braunen Tönen.)  68 Teile dieses Produktes der Formel-

    werden in fein verteilter Form in 1000     Teilen          o-Dichlorbenzol    mit 30 Teilen     Anthrachinon-          2-carbonsäurechlorid    durch mehrstündiges  Kochen kondensiert. Der gebildete Farbstoff  wird noch heiss abgesaugt, gewaschen und ge  trocknet.  



       Beispiel   <I>2:</I>  45 Teile     5,5'-Diamino-diphthaloylcarbazol     werden mit 31 Teilen     Bzl-Brombenzanthron       kondensiert. Das so erhaltene Kondensations  produkt wird     in    fein verteilter Form in  1000 Teilen     o-Dichlorbenzol    durch mehrstün  diges Kochen mit 30 Teilen     Anthrachinon=2-          carbonsäurechlorid    kondensiert.  



  91 Teile des so erhaltenen     Anthrimids     der Formel:

    werden bei etwa 140   C in eine Lösung von  250 Teilen     Natriumanilin    in etwa 800 Tei  len wasserfreiem Anilin eingetragen. Unter  Durchleiten von Stickstoff hält man die Re  aktionsmasse bei dieser Temperatur, bis kein  unverändertes Ausgangsmaterial mehr vor  handen ist: Die erkaltete Schmelze wird auf  überschüssige verdünnte Salzsäure gegossen,  der Niederschlag abgesaugt, gewaschen und  getrocknet.



  Additional patent to main patent No. 194458. Process for the production of a güpenfarbstoifes. The present patent relates to a process for the production of a vat dye, characterized in that 5,5'-diamino-diphthaloylcarbazole is condensed with Bz1-bromobenzanthrone and the condensation product of the formula:
EMI0001.0009
      an alkaline condensing agent and anthraquinone-2-carlionic acid chloride can act on one another.



  The new vat dye dissolves in concentrated sulfuric acid with a bluish green color and colors the vegetable fibers from the brown vat in very real khaki tones. <I> Example 1: </I> 45 parts of 5,5'-diamino-diphthaloylearbazole are condensed with 31 parts of Bzl-bromobenzanthrone and this condensation product is fused with alcoholic potash. (The product obtained dissolves in concentrated sulfuric acid with an olive green color.

   Dissolved from concentrated sulfuric acid; dyes it from brown cotton vat in dark brown shades.) 68 parts of this product of the formula
EMI0002.0012
    are condensed in finely divided form in 1000 parts of o-dichlorobenzene with 30 parts of anthraquinone-2-carboxylic acid chloride by boiling for several hours. The dye formed is filtered off with suction while hot, washed and dried.



       Example <I> 2: </I> 45 parts of 5,5'-diamino-diphthaloylcarbazole are condensed with 31 parts of Bzl-bromobenzanthrone. The condensation product thus obtained is condensed in finely divided form in 1000 parts of o-dichlorobenzene by boiling for several hours with 30 parts of anthraquinone = 2-carboxylic acid chloride.



  91 parts of the anthrimide thus obtained of the formula:
EMI0002.0025
    are entered at about 140 C in a solution of 250 parts of sodium aniline in about 800 parts of anhydrous aniline. While passing nitrogen through, the reaction mass is kept at this temperature until there is no longer any unchanged starting material: the cooled melt is poured onto excess dilute hydrochloric acid, and the precipitate is filtered off with suction, washed and dried.
