Description
Verfahren zur Herstellung eines metallhaltigen Farbstoffes. Es wurde gefunden, dass man einen metall haltigen Farbstoff durch Behandeln des Azo- farbstoffes aus diazotiertem 5-Nitro-2-ainino- 1-plienol und 2-Amiironaphtalin mit kobalt- abgebenden Mitteln in alkalischem Medium erhalten kann, wenn diese Behandlung in Gegenwart von Salzen der Weinsäure erfolgt.
Der erhaltene kobalthaltige Farbstoff stellt ein blauschwarzes Pulver dar, das sich in organischen Lösungsmitteln leicht mit grün blauer Farbe löst und mit Nitro- oder Acetyl- zelluloselacken auf geeigneten Unterlagen grünstichig blaue, bis grünstichig blauschwarze Überzüge ergibt.
Beispiel: 30,8 Teile des Farbstoffes aus diazotiertem 5-Nitro-2-arnirro-l-phenol und 2-Aniinorraphta- linwerden mit 200 Teilen Wasser und 27 Teilen 30 %iger Natronlauge angerührt. Dazu gibt man eine Lösung aris 14,1 Teilen kristalli siertes Kobaltsulfat (C0804.7H20), 3.75 Teilen Weinsäure, 150 Teilen Wasser und 2VTeilen Natronlauge.
Hierauf erwärmt man<B>1</B> bis 2 Stunden auf<B>70-750,</B> versetzt dann bis zur schwach bikarbonatalkalischen Reaktion mit verdünnter Essigsäure, filtriert den ausge schiedenen Farbstoff ab, wäscht neutral und trocknet.
Process for the production of a metal-containing dye. It has been found that a metal-containing dye can be obtained by treating the azo dye from diazotized 5-nitro-2-ainino-1-plienol and 2-amiironaphthalene with cobalt-releasing agents in an alkaline medium, if this treatment is in the presence of Salting of tartaric acid takes place.
The cobalt-containing dye obtained is a blue-black powder which easily dissolves in organic solvents with a green-blue color and, with nitro or acetyl cellulose lacquers, gives greenish-blue to greenish-blue-black coatings on suitable substrates.
Example: 30.8 parts of the dye from diazotized 5-nitro-2-aminirro-1-phenol and 2-aniinorraphthalene are mixed with 200 parts of water and 27 parts of 30% strength sodium hydroxide solution. A solution of 14.1 parts of crystallized cobalt sulfate (C0804.7H20), 3.75 parts of tartaric acid, 150 parts of water and 2 parts of sodium hydroxide solution are added.
The mixture is then heated to <B> 70-750 for 1 to 2 hours, then diluted acetic acid is added until a weakly alkaline bicarbonate reaction occurs, the separated dye is filtered off, washed neutral and dried.
