Description

  

      Zusatzpatent    zum     Hauptpatent    Nr. 200368.    Verfahren zur Herstellung eines neuen     Farbstoffes.       Es wurde gefunden, dass man einen lös  lichen Farbstoff erhält, wenn man auf     1.4-          Di-(p-amiriophenyl)-aminoanthraohinon    in Ge  genwart von     Pyridin    2     Mol        Benzoesäure-3-          sulfochlorid    einwirken lässt. Das neue Pro  dukt bildet ein dunkles Pulver, das sich in  Wasser mit blauer Farbe löst und     Wolle     aus saurein Bade grünblau färbt.  



  <I>Beispiel;</I>  21 Teile     1.4-Di-(p-aminophenyl)-amino-          antbrachinon,    66 Teile     Benzoesäure-3-sulfo-          ohlorid    und 300 Teile     Pyridin    werden so lange  bei 90-100   verrührt, bis eine Probe des  Produktes in angesäuertem Wasser löslich  wird. Nach dem     Abdestillieren    des     Pyridins       wird der Rückstand in Wasser gelöst; die  Lösung mit     Natriumearbonat    alkalisch ge  stellt, kurze Zeit erwärmt und der Farbstoff  mit     Natriumchlorid    gefällt.



      Additional patent to main patent no. 200368. Process for the production of a new dye. It has been found that a soluble dye is obtained if 2 moles of benzoic acid-3-sulfochloride are allowed to act on 1,4-di- (p-amiriophenyl) -aminoanthraohinone in the presence of pyridine. The new product forms a dark powder that dissolves in water with a blue color and dyes wool from acidic baths green-blue.



  <I> Example; </I> 21 parts of 1,4-di- (p-aminophenyl) -amino-antbrachinone, 66 parts of benzoic acid-3-sulfochloride and 300 parts of pyridine are stirred at 90-100 until a sample is obtained of the product becomes soluble in acidified water. After the pyridine has been distilled off, the residue is dissolved in water; the solution is made alkaline with sodium carbonate, warmed for a short time and the dye is precipitated with sodium chloride.
