Description

  

  Verfahren zur Herstellung eines     Anthrachinonderivates.       Es wurde gefunden, dass man ein     Anthra-          chinonderivat    herstellen kann, wenn man auf       1-Halogenanthrachinon        Methylhydrazin    ein  wirken lässt.    Das erhaltene Produkt der Formel  
EMI0001.0006     
    bildet gelbe Nadeln, die bei 188 bis 189    schmelzen. Es löst sich in     konzentrierter     Schwefelsäure mit oranger Farbe; beim Aus  tragen der     Schwefelsäurelösung    erhält man  gelbe Flocken. In Alkohol ist das Produkt  mit gelber Farbe und intensiv grüner Fluor  eszenz etwas löslich.

   Es stellt ein wertvolles  Zwischenprodukt für die Herstellung von       Farbstoffen    dar.    <I>Beispiel:</I>  24 Teile 1     Chloranthrachinon,    18 Teile  einer wässerigen     Methylhydrazinlösung,    die  etwa     30%        Methylhydrazin    enthält, 10 Teile  Soda und 150 Teile     Pyridin    werden     12,Stun-          den    zum     :Sieden    erhitzt. Das Reaktionspro  dukt wird kalt     abfiltriert        und    von anorgani  schen Bestandteilen durch Auskochen mit  Wasser befreit.



  Process for the production of an anthraquinone derivative. It has been found that an anthraquinone derivative can be produced if methylhydrazine is allowed to act on 1-haloanthraquinone. The product of the formula obtained
EMI0001.0006
    forms yellow needles that melt at 188 to 189. It dissolves in concentrated sulfuric acid with an orange color; when wearing the sulfuric acid solution, yellow flakes are obtained. The product, with its yellow color and intense green fluorescence, is somewhat soluble in alcohol.

   It is a valuable intermediate product for the production of dyes. <I> Example: </I> 24 parts of 1 chloranthraquinone, 18 parts of an aqueous methylhydrazine solution containing about 30% methylhydrazine, 10 parts of soda and 150 parts of pyridine become 12, Stun - heated to: boiling. The reaction product is filtered off cold and freed from inorganic constituents by boiling with water.
