Description

  

  Verfahren zur Herstellung eines     Nitrofarbstoffes.            (egcnstand    des vorliegenden Zusatzpaten  tes ist ein Verfahren zur Herstellung eines       Nitrofarbstoffes,    welches dadurch gekenn  zeichnet ist, dass man     4,4'-Dichlor-3,3'-dinitro-          benzophenon    mit     1-Amino-4-methoxybenzol-3-          sulfonsäure    kondensiert.  



  <I>Beispiel:</I>  20 Gewichtsteile     4,4'-Dichlor-3,3'-dinitro-          benzophenon    und 60     Gewiehtsteile    des Na  triumsalzes der     1-Amino-4-methoxybenzol-3-          sulfonsäure    werden in Gegenwart von Glykol  mehrere Stunden bei 1.20  gerührt. Die       Schmelze    wird in Wasser gegossen und aus  gesalzen.  



  Das so erhaltene Produkt stellt ein orange  farbenes Pulver dar, das sieh in Wasser mit.    gelber Farbe löst und Wolle in egalen gelben  Tönen färbt, die sich durch sehr     gute    Licht  echtheit auszeichnen.



  Process for the preparation of a nitro dye. (The object of the present additional patent is a process for the production of a nitro dye, which is characterized in that 4,4'-dichloro-3,3'-dinitrobenzophenone is condensed with 1-amino-4-methoxybenzene-3-sulfonic acid .



  <I> Example: </I> 20 parts by weight 4,4'-dichloro-3,3'-dinitrobenzophenone and 60 parts by weight of the sodium salt of 1-amino-4-methoxybenzene-3-sulfonic acid are several in the presence of glycol Stirred at 1:20 hours. The melt is poured into water and salted out.



  The product obtained in this way is an orange-colored powder that can be seen in water. dissolves yellow color and dyes wool in even yellow tones, which are characterized by very good lightfastness.
