Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 287563.    Verfahren zur Herstellung eines     sauren        Walkfarbstoffes    der     Anthrachinonreihe.            CTegenstand    des vorliegenden Patentes ist  ein Verfahren zur     Herstellung    eines sauren        Talldarbstoffes    der     Anthrachinonreihe,    wel  ches darin besteht, dass man     1-Amino-4-(5',6',     7'.     #S'    -     teti-ahydr        onaplithyl    -1'     );

  -a.minoanthraehi-          noti        '-'-stilfonsäure    durch Behandeln mit einem       1)i-oniierenden    Mittel in den     dibromierten        Ab-          könumling    überführt.

      <I>Beispiel:</I>       47,0    Teile     1-amiiio-l-(5',6',7',8-'tetrahydro-          napht        hyl-1')        -aminoanthrachinon    - 2 -     sulfonsau-          res        Natrium        werden        in        1500        Teilen        90        %        iger          Seliwefelsäure    gelöst.

   Man versetzt die Lösung       finit    26 Teilen Brom und rührt die Masse  6 Stunden lang bei Raumtemperatur und her  nach noch     0'    Stunden lang bei 60 .  



       Naeh    dem Aufarbeiten erhält man einen  Farbstoff, der sich in Wasser mit     rotstichig     blauer Farbe löst. In konzentrierter Schwefel  säure ist seine Lösungsfarbe klar blau; sie       schlägt    beim Zusatz von     Paraformaldehyd     nach grünblau um.  



  Der neue Farbstoff färbt Wolle und an  dere tierische Fasern sowie Nylon in klaren,       rotstieliig    blauen Tönen von hervorragender  Schweiss- und     Walkechtheit    und besitzt ferner  ein ausgezeichnetes     Neutralziehvermögen.  



  <B> Additional patent </B> to main patent no. 287563. Process for the production of an acidic fulled dyestuff of the anthraquinone series. The subject matter of the present patent is a process for the preparation of an acidic tall dari of the anthraquinone series, which consists in that 1-amino-4- (5 ', 6', 7 '. ;

  -a.minoanthraehi- noti '-'- stilfonic acid by treatment with a 1) i-oniating agent in the dibrominated Ab- transferred.

      <I> Example: </I> 47.0 parts of 1-amiiio-1- (5 ', 6', 7 ', 8-' tetrahydronaphthyl-1 ') -aminoanthraquinone - 2 - sulphonic acid sodium dissolved in 1500 parts of 90% strength seliulfuric acid.

   26 parts of bromine are added to the solution, and the mass is stirred for 6 hours at room temperature and after a further 0 'hours at 60.



       After working up, a dye is obtained which dissolves in water with a reddish blue color. In concentrated sulfuric acid, its solution color is clear blue; it changes to green-blue when paraformaldehyde is added.



  The new dye dyes wool and other animal fibers as well as nylon in clear, red-stemmed blue shades of excellent sweat and milled fastness and also has excellent neutral drawability.
