Description

  

      Zusatzpatent    zum Hauptpatent Nr. 189647.    Verfahren zur Darstellung eines neuen     Anthr        achinonfarbstoffes.       Das vorliegende Verfahren betrifft die  Herstellung eines neuen     Arithrachinonfarb-          stoffes    und ist dadurch gekennzeichnet, dass  man     1-Amino-4(2',        6'-dimethylanilido-)        anthra-          chinorr-2-sulfonsäur-e    in Gegenwart von Ätz  natron mit     Glycerin    kondensiert und die er  haltene Verbindung mit Schwefelsäure be  handelt.  



  <I>Beispiel:</I>  Man löst in 100 Teilen Glycerin 10 Teile       Ätznatron    und fügt zur warmen Lösung 10  Teile des     Farbstoffes    der Formel  
EMI0001.0013     
    Nach einstündigem Rühren bei 120   lässt  man auf 80<B>0</B> abkühlen und verdünnt mit    Alkohol, worauf die Base kristallisiert aus  fällt. Sie wird gewaschen, getrocknet und  hierauf in der 5fachen Menge konzentrierter  Schwefelsäure bei<B>150</B> C gelöst. Nach kurzem  Rühren ist eine Probe vollständig wasser  löslich. Man giesst auf     Eis-Salzwassermischung,     saugt den Farbstoff ab, stellt ihn in Wasser  neutral und salzt mit Kochsalz aus.  



  Der erhaltene Farbstoff besitzt die Formel  
EMI0001.0015     
    und färbt Wolle in lebhaften rotvioletten  Tönen an.



      Additional patent to main patent no. 189647. Process for the preparation of a new anthracinone dye. The present process relates to the preparation of a new arithraquinone dye and is characterized in that 1-amino-4 (2 ', 6'-dimethylanilido) anthraquinor-2-sulfonic acid is condensed with glycerol in the presence of caustic soda and the compound he retained is treated with sulfuric acid.



  <I> Example: </I> 10 parts of caustic soda are dissolved in 100 parts of glycerine and 10 parts of the dye of the formula are added to the warm solution
EMI0001.0013
    After stirring for one hour at 120, the mixture is allowed to cool to 80 <B> 0 </B> and diluted with alcohol, whereupon the base crystallizes out. It is washed, dried and then dissolved in 5 times the amount of concentrated sulfuric acid at 150 C. A sample is completely water-soluble after brief stirring. It is poured onto a mixture of ice and salt water, the dye is suctioned off, made neutral in water and salted out with table salt.



  The dye obtained has the formula
EMI0001.0015
    and dyes wool in vivid red-violet tones.
