Description

  

  Zusatzpatent zum Hauptpatent     Nr.   <B>153489.</B>    Verfahren zur Darstellung eines sauren     Farbstoffes    der     Anthrachinonreihe.       Gegenstand dieses Zusatzpatentes ist ein  Verfahren zur Darstellung eines sauren     Parb-          stoffes    der     Anthrachinonreihe,    welches da  durch gekennzeichnet ist,     dass    man 2'-Amino       4'-methyldiphenylmethan-2-earbonsäuremitl-          Amino-4-bromanthrachinon-2-sulionssä,ure    kon  densiert und den so erhaltenen Farbstoff mit  einem sauren, Schwefel enthaltenden Kon  densationsmittel weiter kondensiert.  



  <I>Beispiel:</I>  <B>50</B> Gewichtsteile     2'-amino-4'-methyldi-          phenylmethan-2-earbonsaures,    Natrium wer  den in<B>500</B> Teilen Wasser gelöst und mit  <B>53</B>     Gewiehtsteilen        1-amino-4-bromanthravhi-          non-2-suliosaurem    Natrium, 25 Gewichts  teilen     Natriumbiearbonat    und<B>2,5</B> Gewichts  teilen     Kupferehlorür    so lange bei<B>6.0</B> bis<B>65 ' C</B>  gerührt, bis die Kondensation zum Farbstoff  beendet ist.

   Nach der auf die übliche Weise  vorgenommenen Isolierung und Reinigung  des Reaktionsproduktes erhält man ein blaues       Farbstoffpulver,    welches die tierische Faser    in klaren, blauen Tönen     anfärbt    und folgende  Konstitutionsformel besitzt-  
EMI0001.0019     
    <B>5</B> Gewichtsteile derselben werden unter       R,ühren    in<B>50</B>     Gewichtsteile    konzentrierter  Schwefelsäure bei Zimmertemperatur ein  getragen und drei Stunden bei<B>25</B> bis<B>30 '</B>  gehalten. Dann wird die Mischung in Eis  wasser gegossen, der in braunen Flocken aus  geschiedene Farbstoff filtriert, gewaschen  und getrocknet.

   Das so erhaltene rotbraune  Pulver löst sich in Wasser mit     rotstichig         brauner Farbe und liefert auf Wolle und  Seide echte Brauntöne.



  Additional patent to main patent no. <B> 153489. </B> Process for the preparation of an acidic dye of the anthraquinone series. The subject of this additional patent is a process for the preparation of an acidic parbo- stoff of the anthraquinone series, which is characterized in that 2'-amino-4'-methyldiphenylmethane-2-carboxylic acid is condensed with amino-4-bromoanthraquinone-2-sulfonic acid and further condensing the dye thus obtained with an acidic, sulfur-containing condensing agent.



  <I> Example: </I> <B> 50 </B> parts by weight of 2'-amino-4'-methyldiphenylmethane-2-carboxylic acid, sodium are dissolved in <B> 500 </B> parts of water and with <B> 53 </B> parts by weight of 1-amino-4-bromanthravhinon-2-sulio acid sodium, 25 parts by weight of sodium carbonate and <B> 2.5 </B> parts by weight of copper chloride for as long as <B> 6.0 </B> to <B> 65 'C </B> until the condensation to the dye has ended.

   After the reaction product has been isolated and purified in the usual way, a blue dye powder is obtained which dyes the animal fiber in clear, blue tones and has the following constitutional formula-
EMI0001.0019
    <B> 5 </B> parts by weight of the same are entered under R, in <B> 50 </B> parts by weight of concentrated sulfuric acid at room temperature and three hours at <B> 25 </B> to <B> 30 '< / B> held. Then the mixture is poured into ice water, which is filtered into brown flakes of divorced dye, washed and dried.

   The red-brown powder obtained in this way dissolves in water with a reddish-tinged brown color and produces real brown tones on wool and silk.
