  Zusatzpatent zum Hauptpatent     Nr.    153492.         Verfalu-en    zur Darstellung eines stickstoffhaltigen     Anthrachinonderivates.       Es wurde gefunden,     dass    man einen wert  vollen, grünblauen     Acetatseidefarbstoff    erhält,  wenn man das durch Kondensation von     p-          Diaminoanthrarufin-    oder     p-Diaminochrysaziii-          sulfosäuren    mit     Methylamin    in Gegenwart  von     Hydrosulfit    erhältliche Kondensations  produkt unter Zusatz von Borsäure in orga  nischen Lösungsmitteln mit Anilin konden  siert,

   wobei sehr wahrscheinlich<B>1</B> Hol Anilin  mit einem Hol des Ausgangsmaterials reagiert.  Das Kondensationsprodukt löst sich in orga  nischen Lösungsmitteln mit grünblauer Farbe  und färbt     Acetatseide    nach geeigneter     Ver-          pastung    in reinen, grünblauen Tönen von  vorzüglicher Echtheit.  



  <I>Beispiel:</I>  <B>60</B> Teile der     Leukoverbindung    des am  Stickstoff     monomethylierten        1-Oxy-4,5,8-tri-          aminoantrachinons    (dargestellt nach dem fran  zösischen Zusatzpatent     Nr.   <B>39699</B> der     An-          melderin    vom<B>30.</B> Januar<B>1931)</B> werden in  <B>300</B> Teilen Alkohol mit<B>60</B> Teilen Anilin und  <B>30</B> Teilen Borsäure etwa<B>6</B> Stunden zum    Kochen erhitzt, bis eine Probe, in Alkohol  gelöst, keine weitere     Versebiebung    der grün  blauen Farbe nach Grün aufweist. Man<B>fil-</B>  triert kalt, wäscht den Rückstand mit Was  ser aus.



  Additional patent to main patent No. 153492. Procedure for the preparation of a nitrogen-containing anthraquinone derivative. It has been found that a valuable, green-blue acetate silk dye is obtained if the condensation product obtained by condensation of p-diaminoanthrarufinic or p-diaminochrysaziiisulfonic acids with methylamine in the presence of hydrosulfite is condensed with aniline by adding boric acid in organic solvents sated,

   where very likely <B> 1 </B> Hol aniline reacts with a Hol of the starting material. The condensation product dissolves in organic solvents with a green-blue color and, after suitable pasting, dyes acetate silk in pure, green-blue shades of excellent fastness.



  <I> Example: </I> <B> 60 </B> parts of the leuco compound of 1-oxy-4,5,8-tri-aminoanthraquinone monomethylated on the nitrogen (shown according to the French additional patent no. 39699 </B> by the applicant on <B> 30th </B> January <B> 1931) </B> <B> 300 </B> parts of alcohol are <B> 60 </B> parts Aniline and <B> 30 </B> parts of boric acid are heated to the boil for about <B> 6 </B> hours until a sample, dissolved in alcohol, does not show any further shift from the green-blue color to green. You <B> filter </B> cold, wash the residue with water.

PATENTANSPRUCH: Verfahren zur Darstellung eines Fafb- stoffes der Anthrachinotireihe, dad(irch ge kennzeichnet, dass man das durch Konden sation von p-DiaminoanthrarLifin- oder p-Di- aminochrysazinsulfosäuren mit Methylamin in Gegenwart von HydrosLilfit erhältliche Kon densationsprodukt in organischen Lösungs mitteln in Gegenwart von Borsäure mit Ani lin kondensiert. PATENT CLAIM: Process for the preparation of a dye of the anthraquinoty series, dad (irch denotes that the condensation product obtained by condensation of p-diaminoanthrarifinic or p-diaminochrysazine sulfonic acids with methylamine in the presence of HydrosLilfit is in the presence of organic solvents of boric acid condensed with aniline. Der erhaltene Farbstoff löst sich in orga nischen Lösungsmitteln mit grünblauer Farbe und färbt Acetatseide nach geeigneter Ver- pastung in grünblauen Tönen von vorzüglicher Echtheit. The dye obtained dissolves in organic solvents with a green-blue color and, after suitable pasting, dyes acetate silk in green-blue shades of excellent fastness.
