Description

  

  Verfahren zur Darstellung eines     Ogazins    der     Anthraehinonreihe.       Gegenstand des vorliegenden Zusatz  patentes ist ein Verfahren zur Darstellung  eines     Ogazins    der     Anthrachinonreihe,    welches  dadurch gekennzeichnet ist, dass man     1-brom-          anthrachinon-2-sulfosaures        Natrium    mit     2-          Amino-4-nitrophenol-6-sulfosaurem    Natrium  in Gegenwart eines     säurebindenden    Mittels  kondensiert.  



  <I>Beispiel:</I>  50 Gewichtsteile     1-bromanthrachinon-2-          sulfosaures    Natrium, 50     Gewichtsteile    2  amino-4-nitrophenol-6-sulfosaures     Natrium     (65%ig),<B>30</B> Gewichtsteile Soda, 10 Ge  wichtsteile     Natriumbicarbonat;    2 Gewichts  teile     Kupferchlorür    und 600     Gewichtsteile     Wasser werden 10     Stunden    unter Rühren auf  50 bis 60   C erwärmt. Nach dem Erkalten  wird abgesaugt und der Rückstand auf dem  Filter mit verdünnter     -Kochsalzlösung    ge  waschen.

   Zur weiteren     Reinigung        wird    das  Rohprodukt     in        heissem    Wasser gelöst, die Lö  sung filtriert und der Farbstoff durch Zu-         gabe    von Salzsäure ausgeschieden. Man er  hält     ein        dunkelviolettes        Pulver,    welches aus  saurem Bade Wolle in violetten Tönen färbt.



  Process for the preparation of an ogazin of the anthraehinone 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-bromo-anthraquinone-2-sulfonic acid sodium with 2-amino-4-nitrophenol-6-sulfonic acid sodium in the presence of an acid-binding agent condensed.



  <I> Example: </I> 50 parts by weight of 1-bromoanthraquinone-2-sulfonic acid sodium, 50 parts by weight of 2 amino-4-nitrophenol-6-sulfonic acid sodium (65%), <B> 30 </B> parts by weight of soda, 10 parts by weight of sodium bicarbonate; 2 parts by weight of copper chloride and 600 parts by weight of water are heated to 50 to 60 ° C. for 10 hours while stirring. After cooling, it is suctioned off and the residue is washed on the filter with dilute sodium chloride solution.

   For further purification, the crude product is dissolved in hot water, the solution is filtered and the dye is eliminated by adding hydrochloric acid. He holds a dark violet powder which dyes wool in violet tones from acidic bath.
