  Zusatzpatent zum Hauptpatent     Nr.   <B>156755.</B>    Verfahren zur Herstellung eines     Küpenfarbstoffes    der     Anthrachinonreihe.       Es wurde gefunden,     dass    man einen neuen       Küpenfarbstoff    der     Anthraebinonreihe    erhält,  wenn man auf<B>1</B>     Mol        1,3-Dihalogeriantbra-          chinon    2     Mol        Aminodibenzanthron,

      herge  stellt durch     Nitrierung    von     Dibenzanthron     und Reduktion des erhaltenen     Mononitro-          dibenzanthrons,    einwirken     lässt.     



  Der neue Farbstoff stellt ein dunkles  Pulver dar, das sieh in konzentrierter Schwe  felsäure mit rotvioletter Farbe löst und Baum  wolle in dunkelgrünen Tönen von sehr guter  Echtheit färbt.  



  <I>Beispiel:</I>  <B>3,6</B> Teile     1,3-Dibromanthrachinoti,    9,4 Teile       Aminoclibenzarithron    (erhalten durch     Nitrie-          rung    von     Dibenzanthron    in Nitrobenzol,     Um-          kristallisieren    aus konzentrierter     Schwefel-          8äure    und     Umküpen    unter gleichzeitiger Re  duktion),<B>5</B> Teile wasserfreies     Natriumacetat,

       <B>1</B> Teil Kupferacetat und<B>170</B> Teile     Nitro-          benzol    werden 22 Stunden am     Rückflusskühler     gekocht. Das schwer lösliche Umsetzungs  produkt wird bei<B>70</B>     ('    filtriert, mit     Nitro-          benzol,    dann mit Alkohol gewaschen und  hierauf mit Wasser ausgekocht.    Zu demselben Farbstoff gelangt man, wenn  statt     1,3-Dibromanthrachinon    das     1,3-Dichlor-          anthrachinon    oder das     1-Cblor-3-bromanthra-          chinon    verwendet wird.  



  Ebenso wird dasselbe Resultat erhalten,  wenn das     Natriumacetat    durch     Kaliumacetat     oder     kalzinierte        Alkalikarbonate    oder     Ma-          gnesiumoxyd    und das Kupferacetat durch  andere Kupferverbindungen oder metallisches  Kupfer ersetzt wird.



  Additional patent to main patent no. <B> 156755. </B> Process for the production of a vat dye of the anthraquinone series. It has been found that a new vat dye of the anthraebinone series is obtained if 2 moles of aminodibenzanthrone are added to <B> 1 </B> moles of 1,3-dihalogeriantbraquinone,

      produced by nitration of dibenzanthrone and reduction of the mononitro- dibenzanthrone obtained.



  The new dye is a dark powder that dissolves in concentrated sulfuric acid with a red-violet color and dyes cotton in dark green shades of very good fastness.



  <I> Example: </I> <B> 3.6 </B> parts of 1,3-dibromoanthraquinoti, 9.4 parts of aminoclibenzarithrone (obtained by nitration of dibenzanthrone in nitrobenzene, recrystallization from concentrated sulfuric acid and transferring with simultaneous reduction), <B> 5 </B> parts of anhydrous sodium acetate,

       <B> 1 </B> part of copper acetate and <B> 170 </B> parts of nitrobenzene are boiled in a reflux condenser for 22 hours. The poorly soluble reaction product is filtered at <B> 70 </B> (', washed with nitrobenzene, then with alcohol and then boiled with water. The same dye is obtained if the 1, instead of 1,3-dibromoanthraquinone 3-dichloro-anthraquinone or the 1-Cblor-3-bromoanthraquinone is used.



  The same result is also obtained if the sodium acetate is replaced by potassium acetate or calcined alkali metal carbonates or magnesium oxide and the copper acetate by other copper compounds or metallic copper.
