Description

  

      Zusatzpatent    zum Hauptpatent Nr. 153489.    Verfahren zur Darstellung eines sauren     Farbstoffes    der     Anthraeliinonreihe.       Gegenstand dieses Zusatzpatentes ist ein.  Zierfahren zur Darstellung eines sauren Farb  stoffes der     Anthrachinonreihe,    welches da  durch gekennzeichnet ist, dass man     3'-Amino-          4'-äthogydiphen.ylmethan-2-earbonsäure        mitl        -          Amino-4-bromanthraehinon-2-sulfonsäure    kon  densiert und den so erhaltenen Farbstoff mit  einem sauren, Schwefel enthaltenden Kon  densationsmittel weiter kondensiert.  



  <I>Beispiel:</I>  32 Gewichtsteile     3'-Amino-4'-äthogydiphe-          nylmethan-2-carbonsäure    werden in 400 Tei  len Wasser und 7 Gewichtsteilen Soda gelöst.  Nach Zusatz von 40 Gewichtsteilen     1-amino-          4-bromanthrachinon-2-sulfosaurem    Natrium,       ?0    Gewichtsteilen     Natriumbikarbonat    und  2 Gewichtsteilen     Kupferchlorür    wird das Ge  misch so lange bei 60 bis 70   gerührt, bis  die     Farbstoffbildung    beendigt ist.

   Man er  hält nach der üblichen Reinigung durch Aus  fällen mit Säure und     Umlösen    aus Soda  lösung das Kondensationsprodukt als dunkles    kristallinisches Pulver, welches Wolle und  Seide in     grünstichig    blauen Tönen färbt. Es  besitzt folgende Konstitutionsformel:  
EMI0001.0020     
    10 Gewichtsteile des so erhaltenen Pro  duktes werden unter Rühren in 100 Ge  wichtsteile     Chlorsulfonsäure,    welche auf       -I-    5   C abgekühlt ist, langsam eingetragen.  Nach einstündigem Rühren, wobei die Tem  peratur nicht über     +    25   C ansteigen soll,  wird die Schmelze auf Eis zersetzt, der aus  geschiedene Farbstoff filtriert, gewaschen  und getrocknet.

   Man erhält so ein dunkles           kristallinisches    Pulver, welches auf Wolle  und Seide     grüne    Töne von ausgezeichneter  Wasch- und     Walkechtheit    ergibt.



      Additional patent to main patent No. 153489. Process for the preparation of an acidic dye of the anthraeliinone series. The subject of this additional patent is a. Zierfahren for the representation of an acidic dye of the anthraquinone series, which is characterized by the fact that 3'-amino-4'-ethogydiphen.ylmethane-2-carboxylic acid mitl - amino-4-bromanthraehinone-2-sulfonic acid condenses and the so obtained Dye further condensed with an acidic, sulfur-containing condensing agent.



  <I> Example: </I> 32 parts by weight of 3'-amino-4'-ethogydiphenylmethane-2-carboxylic acid are dissolved in 400 parts of water and 7 parts by weight of soda. After the addition of 40 parts by weight of 1-amino-4-bromoanthraquinone-2-sulfonic acid sodium,? 0 parts by weight of sodium bicarbonate and 2 parts by weight of copper chloride, the mixture is stirred at 60 to 70 until the dye formation is complete.

   After the usual cleaning by precipitating with acid and dissolving from soda solution, he keeps the condensation product as a dark crystalline powder, which dyes wool and silk in greenish blue tones. It has the following constitutional formula:
EMI0001.0020
    10 parts by weight of the product thus obtained are slowly introduced into 100 parts by weight of chlorosulfonic acid, which has cooled to -I- 5 C, with stirring. After stirring for one hour, during which the temperature should not rise above + 25 ° C., the melt is decomposed on ice, and the dyestuff which has separated out is filtered off, washed and dried.

   This gives a dark crystalline powder which, on wool and silk, gives green shades of excellent fastness to washing and boiling.
