Description

  

  <B>Zusatzpatent</B> zum     Hauptpatent    Nr. 194458.    Verfahren zur Herstellung eines     güpenfarbstoffes.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung eines     Küpenfarb-          stoffes,    dadurch gekennzeichnet, dass man       5,5'-Diamino-diphthaloylcarbazol    mit     Bzl-          Brombenzanthron    kondensiert und das Kon  densationsprodukt der Formel:  
EMI0001.0008     
    ein alkalisches Kondensationsmittel und ein       acetylierendes    Mittel     aufeinander    einwirken  lässt.  



  Der neue     güpenfarbstoff    löst sich in kon  zentrierter Schwefelsäure mit olivgrüner  Farbe und färbt die pflanzliche Faser aus  brauner     Küpe    in     Khakitönen    von guten Echt  heitseigenschaften. Nach dem     Umlösen    aus  Schwefelsäure färbt er die pflanzliche Faser  in ebenso echten, grünen Tönen.    <I>Beispiel 1:</I>    45 Teile     5,5'-Diaminodiphthaloylcarba-          zol    werden     mit    31 Teilen     Bzl-Brombenz-          anthron    kondensiert und dieses Kondensa  tionsprodukt mit alkoholischem     Kali    ver  schmolzen.

   (Das erhaltene Produkt löst sich  in konzentrierter Schwefelsäure mit oliv  grüner Farbe. Aus konzentrierter Schwefel  säure umgelöst, färbt es aus brauner     Küpe     Baumwolle in dunkelbraunen Tönen.)      68     Teile    dieses Produktes der     Formel:     
EMI0002.0003     
    werden in fein verteilter Form in 700 Teilen       Essigsäureanhydrid    mehrere Stunden unter       Rückfluss    gekocht.

   Der gebildete Farbstoff  wird abgesaugt, gewaschen und     getrocknet.          Beispiel   <I>2:</I>  45 Teile     5,5'-Diamino-diphthaloylcarbazol     werden mit 31     Teilen        Bzl-Brombenzanthron     kondensiert. Das erhaltene Kondensationspro  dukt wird in fein verteilter     Form    mehrere       Stunden    mit 700 Teilen     Essigsäureanhydrid          unter        Rückfluss    gekocht.  



  72 Teile des so erhaltenen     Anthrimids    der    Formel  
EMI0002.0017     
    werden bei etwa 140   C in eine     Lösung    von  250 Teilen     Natriumanilin    in etwa 800 Teilen  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.



  <B> Additional patent </B> to main patent no. 194458. Process for the production of a high quality dye. The present patent relates to a process for the production of a vat dye, characterized in that 5,5'-diamino-diphthaloylcarbazole is condensed with Bzl-bromobenzanthrone and the condensation product of the formula:
EMI0001.0008
    allowing an alkaline condensing agent and an acetylating agent to act on each other.



  The new güpen dye dissolves in concentrated sulfuric acid with an olive green color and colors the vegetable fiber from the brown vat in khaki tones with good fastness properties. After being dissolved in sulfuric acid, it dyes the vegetable fibers in equally genuine green tones. <I> Example 1: </I> 45 parts of 5,5'-diaminodiphthaloylcarbazole are condensed with 31 parts of Bzl-bromobenzanthrone and this condensation product is melted with alcoholic potash.

   (The product obtained dissolves in concentrated sulfuric acid with an olive green color. Dissolved from concentrated sulfuric acid, it dyes cotton in dark brown tones from a brown vat.) 68 parts of this product of the formula
EMI0002.0003
    are refluxed for several hours in finely divided form in 700 parts of acetic anhydride.

   The dye formed is filtered off with suction, 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 obtained is refluxed in finely divided form with 700 parts of acetic anhydride for several hours.



  72 parts of the anthrimide of the formula thus obtained
EMI0002.0017
    are added at about 140 C in a solution of 250 parts of sodium aniline in about 800 parts of anhydrous aniline. The reaction mass is kept at this temperature while passing nitrogen through it 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.
