Description

  

  Zusatzpatent zum Hauptpatent Nr. 297845.         Gegenstand    des vorliegenden Patentes ist  ein Verfahren zur     Herstellung    eines     Sulfon-          sä.ureamides    der     Anthrachinonreihe,    welches  darin besteht, dass man 1     Mol    des nach der  Schweizer Patentschrift Nr.

   295893     erhältli-          ehen        1,4-Di    -     (2',6'-dimethyl)    -     phenyla,mino-          6,        7-diehloranthrachinondisulfonsäurechlorides     mit 2 --Hol     2-Aminoäthan-l-sulfonsäure    kon  densiert.  



  Im nachfolgenden Beispiel bedeuten die  Teile     Gewichtsteile.     



  <I>Beispiel:</I>  Man verrührt eine feuchte Paste des nach       (len    Angaben der Schweizer Patentschrift       Nr.295893    aus<B>51,5</B> Teilen     1,4-Di-(2',6'-dime-          tliyl)-phenylamino-6,7-dichloranthra.chinon    er  hältlichen     Disulfonsäurechlorides    mit 180 Tei  len einer     200/eigen    Lösung aus     2-aminoät.han-          1-sulfonsaurem    Natrium.

   Nach Zugabe von 20  Teilen     Natriumbicarbonat    und     1.00    Teilen       80o/oigem        Isopropylalkohol    rührt man die       Kondensationsmasse    3 Stunden lang bei 50 .  Dabei wird das Reaktionsgemisch wasserlös  lich. Nun rührt man die     :Masse    noch 2 Stun  den lang bei 80  am     Rückfluss,    versetzt sie mit  SO Teilen     Natriumehlorid    und     rührt    sie kalt.

    Man filtriert das gebildete Kondensationspro-         dukt    ab, wäscht es mit     10o/oiger        Natriumchlo-          ridlösung    neutral und trocknet es.  



  Das neue     Sulfonsäureamid    der     Anthrachi-          nonreihe    löst sich in Wasser und in konzen  trierter Schwefelsäure mit blauer Farbe und  färbt Wolle, Seide,     Tussah    und     synthetische          Polyamidfasern    in blauen Tönen von sehr  guter Walk- und Lichtechtheit.



  Additional patent to the main patent no. 297845. The subject of the present patent is a process for the preparation of a sulfonic acidic acid amide of the anthraquinone series, which consists in adding 1 mol of the substance described in Swiss patent no.

   295893 obtainable 1,4-di- (2 ', 6'-dimethyl) - phenyla, mino- 6, 7-diehloranthraquinone disulfonic acid chlorides condensed with 2 -Hol 2-aminoethane-1-sulfonic acid.



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



  <I> Example: </I> A moist paste of the (len information of Swiss patent specification No. 295893 from <B> 51.5 </B> parts of 1,4-di- (2 ', 6'- Dimethyl) phenylamino-6,7-dichloranthraquinone available disulfonic acid chlorides with 180 parts of a 200 / own solution of 2-aminoät.han- 1-sulfonic acid sodium.

   After addition of 20 parts of sodium bicarbonate and 1.00 part of 80% isopropyl alcohol, the condensation mass is stirred for 3 hours at 50. The reaction mixture becomes water-soluble. The mass is now stirred for 2 hours at 80 reflux, 50 parts of sodium chloride are added to it and it is stirred cold.

    The condensation product formed is filtered off, washed neutral with 10% sodium chloride solution and dried.



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