Description

  

  Verfahren zur Darstellung eines Schwefel- und     stickstoffhaltigen        Anthrachinon-          derivates.       Gegenstand vorliegenden Zusatzpatentes  ist ein Verfahren zur Darstellung eines     schwefel-          und    stickstoffhaltigen     Anthrachinonderivates,     das darin besteht, dass man das     Anthrachinon-          derivat    folgender Formel:  
EMI0001.0009     
    mit     p-Toluidin    zur Umsetzung bringt und die  so erhaltene Farbbase     sulfiert.     



  <I>Beispiel:</I>  50 Gewichtsteile des     Anthrachinonderi-          vates    von folgender Konstitution  
EMI0001.0014     
    werden mit 250 Gewichtsteilen     p-Toluidin     und 14 Gewichtsteilen wasserfreiem Natrium  acetat unter Rühren mehrere Stunden auf       185o    C erhitzt. Darauf wird die etwas er  kaltete Schmelze in Alkohol eingerührt und  das Reaktionsprodukt in üblicher Weise iso  liert. Man erhält so einen Farbstoff, der aus  Chlorbenzol in rotstickig dunkelblauen Nadeln  vom Schmelzpunkt 287-288 o C kristallisiert.  



  8 Gewichtsteile der so erhaltenen     Farb-          base    werden in 140     Clewichtsteilen        Monohydrat         und 20 Gewichtsteilen 20     o/oigetn        Oleum    so  lange verrührt, bis eine Probe völlig wasser  löslich geworden ist. Durch Eingiessen in  Wasser und Abscheiden mit Kochsalz erhält  man einen     Farbstoff,    der auf Wolle klare,     grün-          stichigblaueFärbungen    liefert     endwahrschein-          lich    folgende Konstitution besitzt:  
EMI0002.0008     




  Process for the preparation of a sulfur- and nitrogen-containing anthraquinone derivative. The subject of the present additional patent is a process for the preparation of a sulfur- and nitrogen-containing anthraquinone derivative, which consists in using the anthraquinone derivative of the following formula:
EMI0001.0009
    reacts with p-toluidine and sulfates the resulting color base.



  <I> Example: </I> 50 parts by weight of the anthraquinone derivative of the following constitution
EMI0001.0014
    are heated with 250 parts by weight of p-toluidine and 14 parts by weight of anhydrous sodium acetate with stirring at 185o C for several hours. The slightly cold melt is then stirred into alcohol and the reaction product is isolated in the usual way. In this way a dye is obtained which crystallizes from chlorobenzene in red, dark blue needles with a melting point of 287-288 ° C.



  8 parts by weight of the color base obtained in this way are stirred in 140 parts by weight of monohydrate and 20 parts by weight of 20% oleum until a sample has become completely water-soluble. By pouring it into water and separating it with common salt, a dye is obtained which, on wool, produces clear, greenish-tinged blue dyeings and has the following constitution:
EMI0002.0008
