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 -monomethylanilin- 2 -sulfosäure mit 3-Diäthylisorosindulin-1.6.12-trisulfo- säure der Formel
EMI0001.0010
kondensiert.
Die entstandene Phenonaphto- safranintrisulfosäure enthält eine Sulfo- gruppe in Orthostellung zum Safraninstick- stoff (-16-Stellung), wodurch die vorzügliche Alkaliechtheit der Färbungen bedingt wird.
Der neue Farbstoff ist ein dunkelbron- ziges Pulver, -das in Wasser mit blauer Farbe, in konzentrierter Schwefelsäure grasgrün lös lich ist. <I>Beispiel:</I> 400 Teile einer wässerigen Lösung, ent haltend 31,5 Teile (j/ Mol.)
des Monona- triumsalzes der 3-Diäthy lisorosindulin-1.6.12.. trisulfosäure und 20 Teile Natriumacctat kri- stallisiert werden zusammen mit einer Lö sung von 11 Teilen 1-Amino-5-methyl-4- monomethylanilin-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. Durch Zusatz von Kochsalz wird der Farb stoff als pulveriges Pulver ausgeschieden.
Er färbt die animalische Faser in reinen, licht- und alkaliechten Blautönen. Seine Konsti tution ist folgyende:

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-monomethylaniline-2-sulfonic acid is mixed with 3-diethylisorosindulin-1.6.12-trisulfonic acid of the formula
EMI0001.0010
condensed.
The resulting phenonaphthosafranin trisulfonic acid contains a sulfo group in the ortho position to the safranin nitrogen (-16 position), which is the reason for the excellent alkali fastness of the dyeings.
The new dye is a dark bronze powder that is soluble in water with a blue color, and in concentrated sulfuric acid, grass-green. <I> Example: </I> 400 parts of an aqueous solution, containing 31.5 parts (j / mol.)
of the mononatrium salt of 3-diethy lisorosindulin-1.6.12 .. trisulfonic acid and 20 parts of sodium acetate are crystallized together with a solution of 11 parts of 1-amino-5-methyl-4-monomethylaniline-2-sulfonic acid in 80 parts Water and 3 parts of soda boiled until a sample, dissolved in concentrated sulfuric acid, shows a pure green color. By adding table salt, the dye is excreted as a powdery powder.
It dyes the animal fibers in pure, light and alkaline blue tones. Its constitution is as follows:
