  <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    1,4-Di-(2',4',6'       trimethyl)-phenylaminoanthrachinon-3',3'-di-          sulfonsäurechlorid    mit 2     Mol        2-Methylamino-          äthan-l-sulfonsätire    kondensiert.  



  Im nachfolgenden Beispiel bedeuten die  Teile Gewichtsteile.  



  <I>Beispiel:</I>       Man        verrührt        120        Teile        einer        30        %        igen     wässerigen Lösung aus     2-methylaminoäthan-l.-          sulfonsaurem    Natrium mit 318 Teilen einer  21     o/oigen    feuchten Paste des     1,4-Di-(2',4',-6'-          trimethyl)    -     pheny        laminoanthrachinon    - 3',     3'-di-          sulfonsäurechlorides,

      fügt der Suspension 80  Teile     Isopropylalkohol    und 20 Teile     Natrium-          bicarbonat    zu und rührt die Masse auf dem  Wasserbade 5 Stunden lang bei 50 . Man neu  tralisiert sie nun mit 6 Teilen konzentrierter       Chlorwasserstoffsäure    und destilliert davon,  nach Zugabe von 37 Teilen     Natriumehlorid,     den     Isopropylalkohol    ab.

   Bei 50  filtriert man  das Kondensationsprodukt aus der     zurückblei-          benden        Suspension        ab,        wäscht        es        mit.        5%iger          -_1        atriumehloridlösung    und trocknet es bei 110 .

      Das neue     Sulfonsäureamid    der     Anthra-          ehinonreihe    löst sich in Wasser mit blauer,  in     konzentrierter    Schwefelsäure mit grün  stichig blauer Farbe und färbt Wolle, Seide,       Tussah    und synthetische     Polyamidfasern    in  blauen Tönen von sehr     guter    Walk- und Licht  echtheit.



  <B> Additional patent </B> to main patent no. 297845. Process for the production of a sulfonic acid amide of the anthraquinone series. The present patent relates to a process for the preparation of a sulfonic acid amide of the anthraquinone series, which consists in that 1 mol of 1,4-di- (2 ', 4', 6 'trimethyl) -phenylaminoanthraquinone-3', 3'-di - Sulphonic acid chloride condensed with 2 moles of 2-methylamino ethane-l-sulphonic acid.



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



  <I> Example: </I> 120 parts of a 30% strength aqueous solution of 2-methylaminoethane-l-sulfonic acid sodium are stirred with 318 parts of a 21% moist paste of 1,4-di- (2 ', 4 ', - 6'-trimethyl) - phenylaminoanthraquinone - 3', 3'-disulfonic acid chlorides,

      80 parts of isopropyl alcohol and 20 parts of sodium bicarbonate are added to the suspension and the mass is stirred on the water bath at 50 for 5 hours. It is now neutralized with 6 parts of concentrated hydrochloric acid and, after adding 37 parts of sodium chloride, the isopropyl alcohol is distilled off.

   At 50, the condensation product is filtered off from the suspension that remains and it is washed with. 5% -_1 atrium chloride solution and dry it at 110.

      The new sulphonic acid amide of the anthraquinone series dissolves in water with a blue color, in concentrated sulfuric acid with a green, tinged blue color and dyes wool, silk, tussah and synthetic polyamide fibers in blue tones with very good fulling and lightfastness.
