Description
Verfahren zur Darstellung eines Farbstoffes der Phenonaphtosafraninreihe. Es wurde gefunden, dass ein neuer wert voller Farbstoff entsteht, wenn man 1-Amino- 4-dimethylanilin-2-sulfosäure mit 3-Dimethyl- isorosindulin-1- 6 # 12-trisulfosäure der Formel
EMI0001.0008
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.
<I>Beispiel:</I> 400 Teile einer wässerigen Lösung, ent- haltend 30 Teile ('/?,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-4-di- methylanilin-2-sulfosäure in 80 Teilen Wasser und 3,1 Teilen Soda so lange gekocht, bis eine .Probe, in konzentrierter Schwefelsäure 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

Process for the preparation of a dye of the phenonaphtosafranine series. It has been found that a new valuable dye is created when 1-amino-4-dimethylaniline-2-sulfonic acid is mixed with 3-dimethyl isorosindulin-1- 6 # 12-trisulfonic acid of the formula
EMI0001.0008
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.
<I> Example: </I> 400 parts of an aqueous solution containing 30 parts ('/?, Molecule) of the monosodium salt of 3-dimethylisorosindulin-1-6-12-trisulfonic acid and 20 parts of sodium acetate are crystallized together Boiled with a solution of 12 parts of 1-amino-4-dimethylaniline-2-sulfonic acid in 80 parts of water and 3.1 parts of soda 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-proof and light-fast blue.
Its constitution is as follows
