Description

  

      Verfahren    zur Darstellung eines     Farbstoffes    der     Phenonaphtosafraninreihe.       Es wurde gefunden, dass ein neuer, wert  voller Farbstoff entsteht, wenn man     1-Amino-          5-methyl-4-monoäthylanilin-2-sulfosäure    mit       3-Dimethylisorosindulin-1        #    6     #        12-trisulfosäure     der Formel  
EMI0001.0010     
    kondensiert.

   Die entstandene     Phenonaphto-          safranintrisulfosäure    enthält eine     Sulfogruppe     in     Orthostellung    zum     Safraninstickstoff        (-16-          Stellung),    wodurch die vorzügliche Alkali  echtheit der Färbungen bedingt wird.    Der neue     Farbstoff    ist ein dunkles Pulver,  das in Wasser mit blauer Farbe, in konzen  trierter Schwefelsäure grasgrün löslich ist.

           Beispiel:     400 Teile einer wässerigen Lösung, ent  haltend 30 Teile     ('/2    Molekül) des Mono  natriumsalzes der     3-Dimethylisorosindulin-          1        #    6     #        12-trisulfosäure    und 20 Teile Natrium  azetat kristallisiert werden zusammen mit  einer Lösung von 12 Teilen     1-Amino-5-methyl-          4-monoäthylanilin-2-sulfosäure    in 80 Teilen  Wasser und 3 Teilen Soda so lange gekocht,  bis eine Probe, in konzentrierter Schwefel  säure gelöst, eine rein grüne Farbe zeigt.

    Der mit Kochsalz ausgeschiedene     Farbstoff     färbt die animalische Faser aus saurem Bade       alkali-    und lichtecht blau. Seine Konstitution  ist folgende:  
EMI0001.0030     




      Process for the preparation of a dye of the phenonaphtosafranine series. It has been found that a new, valuable dye is produced if 1-amino-5-methyl-4-monoethylaniline-2-sulfonic acid is mixed with 3-dimethylisorosindulin-1 # 6 # 12-trisulfonic acid of the formula
EMI0001.0010
    condensed.

   The resulting phenonaphthosafranin trisulphonic acid contains a sulpho group in the ortho position to the safranin nitrogen (-16 position), which determines the excellent alkali fastness of the dyeings. The new dye is a dark powder that is soluble in water with a blue color, and in concentrated sulfuric acid it is grass-green.

           Example: 400 parts of an aqueous solution containing 30 parts (1/2 molecule) of the monosodium salt of 3-dimethylisorosindulin- 1 # 6 # 12-trisulfonic acid and 20 parts of sodium acetate are crystallized together with a solution of 12 parts of 1-amino -5-methyl- 4-monoethylaniline-2-sulfonic acid in 80 parts of water and 3 parts of soda boiled until a sample, dissolved in concentrated sulfuric acid, shows a pure green color.

    The dyestuff excreted with common salt dyes the animal fibers from acidic baths, alkali and lightfast blue. Its constitution is as follows:
EMI0001.0030
