Description

  

  Verfahren zur Herstellung eines     Farbstoffes    der     Anthrachinonreihe.       Gegenstand dieses     Zusatzpatentes        ist    ein  Verfahren zur     Herstellung    eines     Farbstoffes     der     Anthrachinonreihe,    welches dadurch ge  kennzeichnet ist, dass man     1-jodanthrachinon-          2-sulfosaures    Kalium mit     1,2-Diamino-4,5-          dichlorbenzol    kondensiert.

      <I>Beispiel:</I>    14     Gewichtsteile        1-jodanthrachinon-2-          sulfosaures    Kalium, 7 Gewichtsteile     1,2-          Diamino-4,5.dichlorbenzol,    4     Gewichtsteile          Soda.,    0,5     Gewichtsteile        Kupferchlorür    wer  den in einer     Mischung    aus 120 Gewichtstei  len Wasser und 25     Gewichtsteilen    Holzgeist  1 Stunde auf 55 bis<B>60'</B>     unter    Rühren er  wärmt, wobei das     Umsetzungsprodukt    in       roten    Nadeln ausfällt.

   Nach dem Erkalten  saugt man ab und wäscht mit verdünnter  Kochsalzlösung aus. Das Produkt     kann,    ge  gebenenfalls durch     Lösen    in Wasser und       Aussalzen    mit Kochsalz gereinigt     werden.       Der Farbstoff zieht auf Wolle und Seide in  echten braunen Tönen.



  Process for the preparation of a dye of the anthraquinone series. The subject of this additional patent is a process for the production of a dye of the anthraquinone series, which is characterized in that 1-iodanthraquinone-2-sulfonic acid potassium is condensed with 1,2-diamino-4,5-dichlorobenzene.

      <I> Example: </I> 14 parts by weight of 1-iodanthraquinone-2-sulphonic acid potassium, 7 parts by weight of 1,2-diamino-4,5.dichlorobenzene, 4 parts by weight of soda., 0.5 parts by weight of copper chloride in a mixture of 120 parts by weight of water and 25 parts by weight of wood spirit are heated to 55 to 60 'for 1 hour while stirring, the reaction product precipitating in red needles.

   After cooling, it is suctioned off and washed with dilute saline solution. The product can, if necessary, be cleaned by dissolving it in water and salting out with common salt. The dye pulls on wool and silk in real brown tones.
