Description

  

  <B>Zusatzpatent</B>     zum    Hauptpatent     Nr.189137.       Verfahren     zur    Herstellung eines     Anthrachinonderivates.       Es     wurde    gefunden, dass man     ein        Anthra-          chinonderivat        herstellen    kann, wenn man auf  1 -     Amno    - 5 -     halogenanthrachinon        Methyl-          hydrazin        einwirken    lässt.  



  Das erhaltene Produkt der Formel  
EMI0001.0015     
    bildet     orangegefärbte        Kristalle,        die        bei        2434          bis    235   schmelzen     und    sich in konzentrier  ter Schwefelsäure mit     oranger    Färbe lösen.  Das neue Produkt stellt     ein        wertvolles    Zwi  schenprodukt für die     Herstellung    von Farb  stoffen dar.  



  <I>Beispiel:</I>  1,3 Teile     1,5-Aminochloranthrachinon,    18  Teile etwa     30prozentige        wässerige        Methyl-          hydrazinlösung,    5 Teile .Soda und 150 Teile       Pyridin    werden 10 Stunden zum Sieden er-         hitzt.    Nach Erkalten wird     abfiltriert,    mit  heissem     Wasser        gewaschen    und ,getrocknet.



  <B> Additional patent </B> to main patent number 189137. Process for the production of an anthraquinone derivative. It has been found that an anthraquinone derivative can be produced if 1 - amno - 5 - halogenanthraquinone methylhydrazine is allowed to act.



  The product of the formula obtained
EMI0001.0015
    forms orange-colored crystals that melt at 2434 to 235 and dissolve in concentrated sulfuric acid with an orange color. The new product is a valuable intermediate product for the manufacture of dyes.



  <I> Example: </I> 1.3 parts of 1,5-aminochloranthraquinone, 18 parts of about 30 percent aqueous methylhydrazine solution, 5 parts of soda and 150 parts of pyridine are heated to the boil for 10 hours. After cooling, it is filtered off, washed with hot water and dried.
