Description

  

  Verfahren zur Darstellung eines     Ogazins    der     Anthrachinonreihe.       Gegenstand des vorliegenden Zusatz  patentes ist ein Verfahren zur     Darstellung     eines     Ogazins    der     Anthrachinonreihe,    welches  dadurch gekennzeichnet ist, dass man     1-jod-          anthrachinon-2-sulfosaures        Kalium    mit     3-          Amino    -4     -hydrogy-1-methylbenzol    - 5 -     sulf    o  säure in Gegenwart eines     säurebindenden     Mittels kondensiert.  



  <I>Beispiel:</I>  22,5 Gewichtsteile     1-jodanthrachinon-2-          sulfosaures        Kalium,    15 Gewichtsteile 3  Amino -4     -hydrogy-1-        methylbenzol    - 5 -     sulfo-          säure,    15 . Gewichtsteile Soda     calciniert,     15     Gewichtsteile        Natriumbicarbonat,    1 Ge  wichtsteil     Kupferchlorür        und    300 Gewichts  teile Wasser werden 10 Stunden bei 50 bis  <B>60'</B> C gerührt.

   Nach Erkalten wird die aus  geschiedene     Anthrachinonogazin-methylsulfo-          säure        abfiltriert    und mit 5     %iger    Kochsalz  lösung ausgewaschen. Danach wird mit 3     %-          iger    Salzsäure gewaschen, abgesaugt und der  Farbstoff in sehr verdünnter Salzsäure gelöst    und geklärt. Aus der Lösung isoliert man  den Farbstoff durch Zugabe von konzentrier  ter Salzsäure und Erwärmen. Man erhält so  ein blaues Pulver, welches in Wasser mit  blauvioletter Farbe löslich ist und Wolle     aus     saurem Bade in     violetten    Tönen färbt.



  Process for the preparation of an ogazine of the anthraquinone series. The subject of the present additional patent is a process for the preparation of an ogazine of the anthraquinone series, which is characterized in that 1-iodo-anthraquinone-2-sulfonic acid potassium with 3-amino -4 -hydrogy-1-methylbenzene-5-sulfo acid condensed in the presence of an acid-binding agent.



  <I> Example: </I> 22.5 parts by weight of 1-iodanthraquinone-2-sulfonic acid potassium, 15 parts by weight of 3 amino -4 -hydrogy-1-methylbenzene-5-sulfonic acid, 15 Parts by weight of soda ash, 15 parts by weight of sodium bicarbonate, 1 part by weight of copper chloride and 300 parts by weight of water are stirred at 50 to 60 ° C. for 10 hours.

   After cooling, the separated anthraquinonogazine methylsulfonic acid is filtered off and washed out with 5% sodium chloride solution. Then it is washed with 3% hydrochloric acid, filtered off with suction and the dye is dissolved and clarified in very dilute hydrochloric acid. The dye is isolated from the solution by adding concentrated hydrochloric acid and heating. The result is a blue powder which is soluble in water with a blue-violet color and which dyes wool from an acid bath in violet shades.
