  <B>Zusatzpatent</B>     zum    Hauptpatent Nr. 297845.    Verfahren     zur        Herstellung    eines     Sulfonsäureamides    der     Anthrachinonreihe.            Gegenstand    des vorliegenden Patentes ist  ein Verfahren zur Herstellung eines     Sulfon-          säureamides    der     Anthrachinonreihe,    welches  darin besteht, dass man 1     Mol.    des nach der  Schweizer Patentschrift     Nr.295891    erhältli  chen     1,4-Di    -     (2',6'-dimethyl)

      -     phenyla.mino-          anthraehinondisulfonsärarechlorides    mit 2     Mol          1.-Arnino-),4-dimethylbenzol-5-siilfonsäure    kon  clensiert.  



  Im nachfolgenden Beispiel bedeuten die  Teile     Gewichtsteile.     



       Beispiel:     In eine Suspension     vors    26,5 Teilen     1-amino-          2,4-dimethylbenzol-5-sulfonsaurem    Natrium,  12 Teilen     Natriumbicarbonat    und 12 Teilen       Natriumehlorid    in 100 Teilen Wasser trägt  man innerhalb von einer Stunde bei 55 bis 60        eine    feuchte Paste des nach den Angaben der       S'ehweizer    Patentschrift     Nr.295891    aus 22,3  Teilen     1,4-Di-(2',6'-dimethyl)

  -phenylamino-          anthraehinon    erhältlichen     Disulfonsäureehlo-          rides    in kleinen Portionen ein und rührt die       Masse    36 Stunden lang weiter. Nach Ablauf  dieser Zeit löst sich eine Probe der Masse in  1     o/oif-er        Natriumearbonatlösung-    mit blauer  Farbe. Man fällt nun das Kondensationspro  dukt durch     Zugabe    von weiteren 12 Teilen       Natriumchlorid    zur     Kondensationsmasse    aus,  filtriert es, wäscht es und trocknet, es.  



  Der neue Farbstoff der     Anthraeliinonreilie     ist ein Gemisch aus Mono- und Dikondensa-         tionsprodukt;    er löst sich in Wasser mit  blauer, in konzentrierter Schwefelsäure mit  rotblauer Farbe und färbt Wolle, Seide,     Tus-          sah    und synthetische     Polyamidfasern    in leb  haften blauen Tönen von guter Walk-     und     Lichtechtheit.



  <B> Additional patent </B> to main patent no. 297845. Process for the production of a sulfonic acid amide of the anthraquinone series. The subject of the present patent is a process for the preparation of a sulfonic acid amide of the anthraquinone series, which consists in adding 1 mol of the 1,4-di- (2 ', 6'-dimethyl) obtainable according to Swiss patent specification No. 295891

      - phenyla.mino- anthraehinondisulfonsärarechlorides with 2 mol 1.-Amino-), 4-dimethylbenzene-5-siilfonsäure kon clensed.



  In the following example, the parts are parts by weight.



       Example: In a suspension of 26.5 parts of 1-amino-2,4-dimethylbenzene-5-sulfonic acid sodium, 12 parts of sodium bicarbonate and 12 parts of sodium chloride in 100 parts of water, a moist paste is carried over the course of one hour at 55-60 according to the information in Swiss patent specification 295891 from 22.3 parts of 1,4-di- (2 ', 6'-dimethyl)

  -phenylamino-anthraehinon available disulfonic acid halides in small portions and stir the mass for 36 hours. After this time has elapsed, a sample of the mass dissolves in 10% sodium carbonate solution with a blue color. The condensation product is now precipitated by adding a further 12 parts of sodium chloride to the condensation mass, it is filtered, washed and dried.



  The new dye of the Anthraeliinonreilie is a mixture of mono- and dicondensation product; it dissolves in water with a blue color, in concentrated sulfuric acid with a red-blue color and dyes wool, silk, tusks and synthetic polyamide fibers in vivid blue shades of good fullness and lightfastness.
