  Zusatzpatent zum Hauptpatent Nr. 266373.    Verfahren zur Herstellung eines neuen Farbstoffes der     Anthrachinonreihe.       Das vorliegende Patent betrifft, ein Ver  fahren zur Herstellung eines neuen     Anthra-          chinonfarbst.offes    und ist dadurch gekenn  zeichnet, dass man ein Gemisch von     Leuko-6-          chlorchinizarin    und     6-Chlorchinizarin    mit     4-          Amino-diphenylmethan    kondensiert und die  erhaltene Base sulfoniert.  



  <I>Beispiel:</I>  6 Teile     Leuko-6-chlorchinizarin,    6 Teile       6-Chlorchinizarin,    6 Teile Borsäure, 20 Teile       4-Aminodiphenylmethan    und 100 Teile     Amyl-          alkohol    werden bei 100-1200 gerührt, bis die  Kondensation beendet ist. Nach Oxydation  mit einem     Luftstrom,    gegebenenfalls bei Ge  genwart von etwas     Piperidin    und Kupfer-         acetat,    wird filtriert, mit Alkohol und schliess  lich mit, heissem Wasser gewaschen. Die erhal  tene Base kann durch Kristallisation aus orga  nischen     Lösungsmitteln    gereinigt werden.

   Sie  besteht aus dunkeln Kristallen, die sich in  organischen Lösungsmitteln     grün    lösen.  



  10 Teile der erhaltenen Base werden in der       4-10fachen        Menge        Schwefelsäure        95-100%     gelöst und gerührt, bis eine Probe in Wasser  leicht löslich geworden ist. Der Farbstoff wird  auf übliche Weise abgetrennt und färbt: Wolle  in gelbgrünen Tönen von ausgezeichneten       Echtheiten    an. Er stellt ein dunkles Pulver  dar, das "sich in Wasser mit grüner Farbe löst,  und besitzt die Formel  
EMI0001.0024     




  Additional patent to main patent No. 266373. Process for the production of a new dye of the anthraquinone series. The present patent relates to a process for the production of a new Anthraquinonfarbst.offes and is characterized in that a mixture of leuco-6-chloroquinizarin and 6-chloroquinizarin is condensed with 4-aminodiphenylmethane and the base obtained is sulfonated.



  <I> Example: </I> 6 parts of leuco-6-chloroquinizarin, 6 parts of 6-chloroquinizarin, 6 parts of boric acid, 20 parts of 4-aminodiphenylmethane and 100 parts of amyl alcohol are stirred at 100-1200 until the condensation has ended . After oxidation with a stream of air, if necessary in the presence of a little piperidine and copper acetate, it is filtered, washed with alcohol and finally with hot water. The base obtained can be purified by crystallization from organic solvents.

   It consists of dark crystals that dissolve green in organic solvents.



  10 parts of the base obtained are dissolved in 4-10 times the amount of 95-100% sulfuric acid and stirred until a sample has become readily soluble in water. The dye is separated off and dyed in the usual way: wool in yellow-green shades with excellent fastness properties. It is a dark powder that "dissolves in water with a green color, and has the formula
EMI0001.0024
