  Zusatzpatent     zum    Hauptpatent Nr. 208542.    Verfahren zur Herstellung eines     Phenanthrenderivates.       Es wurde gefunden, dass ein     Phenanthren-          derivat    hergestellt werden kann, wenn man       Di-    (5'     -benzoylamino-1'-        anthrachinonyl)    -     di-          amino-l-methyl-7-isopropylphenanthren,

      das  durch     Dibromieren    von     Reten    und Umsetzun  gen des     Dibromretens    mit 2     Mol        1-Amino-5-          benzoy        laminoanthrachinon    erhältlich ist, mit  kondensierenden Mitteln behandelt.  



  Das neue     Phenanthrenderivat    stellt ein  schwarzes Pulver dar, das Baumwolle aus  rotbrauner     $üpe    in rotbraunen Tönen färbt.  



  Für die Behandlung mit kondensierenden  Mitteln     kommen    insbesondere saure konden  sierende Mittel, z. B. konzentrierte Schwefel  säure und     Chlorsulfonsäure    in Betracht. Die  Behandlung kann bei tiefer, mittlerer oder  erhöhter Temperatur vorgenommen werden.  Es ist von Vorteil, der Behandlung mit kon  densierenden Mitteln eine oxydierende Be  handlung folgen zu lassen, beispielsweise mit       Natriumnitrit,        -perborat    oder     -hypochlorit    in  saurem Medium. Das erhaltene Produkt kann    weiterhin durch Umfällen,     Umküpen    oder       Umkristallisieren    gereinigt werden.  



  Das als Ausgangsmaterial verwendete Di       (5'-benzoylamino-1'-anthrachinonyl)-diamino-          1-methyl-7-isopropylphenanthren    kann     wie     folgt hergestellt werden:  Zu einer kalten Lösung von 117 Teilen       Reten        (1-Methyl-7-isopropylphenanthren)    in  480 Teilen     Tetrachlorkohlenstoff    gibt man  0,5 Teile     Ferrichlorid    und lässt hierauf im  Dunkeln 168 Teile Brom langsam     zutropfen.     Nachdem die     Bromwasserstoffentwicklung     beendigt ist, wird das Lösungsmittel ab  destilliert und der Rückstand, eine zähflüs  sige, klebrige Masse,

   aus Eisessig oder Al  kohol wiederholt     umkristallisiert.    Man erhält  so feine, farblose     Nädelchen,    die bei 122         schmelzen.    Auf Grund der Analyse liegt     ein          Dibrom    -1 -     methyl    - 7 -     isopropylphenanthren     vor     (gef.        Br.    40,6%,     ber.        Br.    40,8%).

  Additional patent to main patent no. 208542. Process for the production of a phenanthrene derivative. It has been found that a phenanthrene derivative can be produced if di- (5 '-benzoylamino-1'-anthraquinonyl) - di-amino-1-methyl-7-isopropylphenanthrene,

      which is obtainable by dibrominating Reten and Umsetzun gene of Dibromretens with 2 mol of 1-amino-5-benzoy laminoanthraquinone, treated with condensing agents.



  The new phenanthrene derivative is a black powder that dyes cotton from red-brown oil in red-brown tones.



  For treatment with condensing agents, in particular, acidic condensing agents such. B. concentrated sulfuric acid and chlorosulfonic acid into consideration. The treatment can be carried out at low, medium or elevated temperatures. It is advantageous to allow the treatment with condensing agents to be followed by an oxidizing treatment, for example with sodium nitrite, perborate or hypochlorite in an acidic medium. The product obtained can furthermore be purified by reprecipitation, recirculation or recrystallization.



  The di (5'-benzoylamino-1'-anthraquinonyl) -diamino-1-methyl-7-isopropylphenanthrene used as starting material can be prepared as follows: To a cold solution of 117 parts of retene (1-methyl-7-isopropylphenanthrene) in 480 parts of carbon tetrachloride are added to 0.5 part of ferric chloride and 168 parts of bromine are slowly added dropwise in the dark. After the evolution of hydrogen bromide is over, the solvent is distilled off and the residue, a viscous, sticky mass,

   repeatedly recrystallized from glacial acetic acid or alcohol. This gives fine, colorless needles which melt at 122. On the basis of the analysis, a dibromo -1-methyl-7-isopropylphenanthrene is present (found Br. 40.6%, calculated Br. 40.8%).



  19.6 parts of the resulting di-bromo-1-methyl-7-isopropylphenanthrene with a melting point of 122 ', 84.2 parts of 1-amino-5-benzoylaminoanthraquinone, 15 parts of anhydrous sodium carbonate, 15 parts of dehydrated sodium acetate and 1 5 parts of Is.upferchloriir are boiled in 400 parts of dry nitrobenzene for 16 hours with stirring. The precipitated product is sucked off hot, washed with nitrobenzene and alcohol and boiled with dilute hydrochloric acid. A brown powder is obtained.

    that at 400., under. Decomposition melts and dissolves in concentrated sulfuric acid with a grass green color.



  <I> Example: </I> 1 part of di- (5'-benzoyla, mino-1'-anthraquinonyl) -diamino-1-methyl-7-isopropylphenanthene is converted into 18 parts of 96% sulfuric acid entered and stirred for 5 hours at <B> 290 '</B>. The solution is put on ice. add 0.3 parts sodium triimnitrite and stir for 16 hours at 0 to 5.
