Description

  

  Verfahren zur Darstellung eines     Farbstoffes    der     Phenonaphtosafr        aninreihe.       Es     wurde    gefunden, dass ein neuer, wert  voller Farbstoff entsteht, wenn man     1-Amino-          5-methyl-4-monoäthylanilin-2-sulfosäure    mit  3     -Diäthylisorosindulin-1    . 6. 13     -trisulf        osäure     der Formel  
EMI0001.0010     
    kondensiert.

   Die entstandene     Phenonaphto-          safranintrisulfosäure    enthält eine     Sulfo-          gruppe    in     Orthostellung        zum        Safraninstick-          stoff        (-16-Stellung),    wodurch die vorzüg  liche     Alkaliechtheit    der Färbungen bedingt  wird.  



  Der neue Farbstoff ist ein     dunkelbron-          ziges    Pulver, das in Wasser mit blauer Farbe,  in konzentrierter Schwefelsäure grasgrün  löslich ist.    <I>Beispiel:</I>  400 Teile einer wässerigen Lösung, ent  haltend 31,5 Teile     (i/2        Mol.)    des     Mono-          natriumsalzes    der     3-Diäthylisorosindulin-          1.    6.

       13-trisulfosäure    und 20 Teile Natrium  azetat kristallisiert werden     zusammen    mit  einer Lösung von 12 Teilen     1-Amino-5-me-          thyl-4-monoäthylanilin-2-sulfosäure    in 80  Teilen Wasser und 3 Teilen Soda so lange  gekocht, bis eine Probe, in konzentrierter  Schwefelsäure gelöst, eine rein     grüne    Farbe  zeigt. Auf Zusatz von Kochsalz fällt der  Farbstoff als     kupferiges    Pulver aus. Er  färbt die animalische Faser aus saurem Bade  licht- und     alkaliecht        reinblau.    Seine Konsti  tution ist folgende:  
EMI0001.0037     




  Process for the preparation of a dye of the phenonaphtosafranine series. It has been found that a new, valuable dye is formed if 1-amino-5-methyl-4-monoethylaniline-2-sulfonic acid is mixed with 3-diethylisorosindulin-1. 6. 13 -trisulfonic acid of the formula
EMI0001.0010
    condensed.

   The resulting phenonaphthosafranin trisulphonic acid contains a sulpho group in the ortho position to the safranine nitrogen (-16 position), which means that the dyeings are particularly fast to alkali.



  The new dye is a dark bronze powder that is soluble in water with a blue color, and in concentrated sulfuric acid it is grass-green. <I> Example: </I> 400 parts of an aqueous solution containing 31.5 parts (i / 2 mol.) Of the monosodium salt of 3-diethylisorosindulin-1 6.

       13-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. Upon addition of table salt, the dye precipitates as a coppery powder. It dyes the animal fibers from acidic baths light and alkali-like pure blue. Its constitution is as follows:
