Description

  

  Zusatzpatent zum Hauptpatent Nr. 257722.    Verfahren zur Herstellung eines     Küpenfarbatoffes.       Es wurde gefunden, dass ein wertvoller       Küpenfarbstoff    hergestellt werden kann, wenn  man das Kondensationsprodukt aus 1     Mol            3',6'-Diehl.or-monophthaloyl-pyrenolin    und  2     Mol        4-Amino-1,1'-dianthrimid    der Formel  
EMI0001.0007     
    mit     earbazolierenden    Mitteln behandelt.

        Der neue Farbstoff ist ein dunkles Pulver,  das sich in     konz.    Schwefelsäure mit brauner  Farbe löst -und Baumwolle aus brauner     Küpe     in farbstarken,     grünstichigen        Olivtönen    färbt.

           Beisviel:     1,5 Teile des aus 1     Mol        3',6'-Dichlor-mono-          phthaloyl-pyrenolin    und 2     Mol        4-Amino-          anthrachinon-1,1'-dianthrimid    durch Erhitzen  in Nitrobenzol unter     Kupferacetatzusatz    er  hältlichen     Kondensationsproduktes    werden bei  1000 in     eine    Schmelze von 20 Teilen Alumi  niumchlorid und 50 Teilen trockenem     Pyridin     eingetragen und die Temperatur auf 140 bis  1420 erhöht,

   wobei     eine    kleine Menge     Pyridin            abdestilliert.    Dann wird     zwei    Stunden bei 140  bis 1420 gerührt und die Reaktionsmasse in       Wasser-    ausgetragen, mit Natronlauge     phenol-          phthalein-alkalisch    gestellt und mit     Natrium-          hydrosulfit        verküpt.    Nach dem     Abfiltrieren     von wenig Unlöslichem wird der Farbstoff  mit Luft ausgeblasen,     abfiltriert,    ausgewa  schen und getrocknet.



  Additional patent to main patent No. 257722. Process for the production of a vat colorant. It has been found that a valuable vat dye can be produced if the condensation product of 1 mole of 3 ', 6'-Diehl.or-monophthaloyl-pyrenoline and 2 moles of 4-amino-1,1'-dianthrimide of the formula
EMI0001.0007
    treated with earbazolating agents.

        The new dye is a dark powder that is in conc. Sulfuric acid with a brown color dissolves and dyes cotton from a brown vat in strong, greenish olive tones.

           For example: 1.5 parts of the condensation product obtained from 1 mole of 3 ', 6'-dichloro-monophthaloyl-pyrenoline and 2 moles of 4-aminoanthraquinone-1,1'-dianthrimide by heating in nitrobenzene with the addition of copper acetate are obtained at 1000 entered in a melt of 20 parts of aluminum chloride and 50 parts of dry pyridine and increased the temperature to 140 to 1420,

   with a small amount of pyridine distilling off. The mixture is then stirred for two hours at 140 to 1420 and the reaction mixture is poured into water, made phenol-phthalein-alkaline with sodium hydroxide solution and vat with sodium hydrosulfite. After filtering off little insoluble matter, the dye is blown out with air, filtered off, washed out and dried.
