Description
Verfahren zur Herstellung eines metallhaltigen Farbstoffes. Es wurde gefunden, dass man einen me tallhaltigen Farbstoff durch Behandeln des Azofarbstoffes aus dianotiertem 4-Nitro-2- amino-l-phenol und 1.3-Dioxybenzol mit kotalt- und aluminiumabgebenden Mitteln in alkalischem Medium erhalten kann, wenn diese Behandlung in Gegenwart von Salzen der Weinsäure erfolgt.
Der erhaltene kotalt- und aluminiumhaltige Farbstoff stellt ein rotes Pulver dar, das sich in Alkohol löst und aus einer Lösung in Nitro- oder Acetylzelluloselack auf geeigne ten Unterlagen rotorange gefärbte, lichtechte Überzüge gibt.
<I>Beispiel:</I> 27,5 Teile des Farbstoffes aus dianotier tem 4-Nitr-o-2-amirio-l-phenol und 1.3-Dioxy- benzol werden in 250 Teilen Wasser und 12 Teilen 30 0% iger Natronlauge gelöst und bei 400 mit einer Lösung aus 22,4 Teilen kristallisiertem Kobaltsulfat, 6,8 Teilen kri stallisiertem Aluminiumsulfat, 7,
5 Teilen Weinsäure und 50 Teilen 30 % iger Natron- lauge versetzt und während einiger Zeit auf <B>70-800</B> erwärmt. Hierauf gibt man weitere 15 Teile Natronlauge zu, filtriert die Farb- stofflösung von etwas Ungelöstem ab und neutralisiert das Filtrat mit verdünnter Ameisensäure. Der ausgefallene Farbstoff wird abfiltriert, ausgewaschen und bei mässiger Temperatur getrocknet.
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 dianotized 4-nitro-2-amino-1-phenol and 1,3-dioxybenzene with cold and aluminum donating agents in an alkaline medium, if this treatment is carried out in the presence of salts the tartaric acid takes place.
The resulting kotalt- and aluminum-containing dye is a red powder that dissolves in alcohol and gives red-orange colored, lightfast coatings from a solution in nitro or acetylcellulose lacquer on suitable substrates.
<I> Example: </I> 27.5 parts of the dyestuff from dianotier tem 4-nitr-o-2-amirio-1-phenol and 1,3-dioxybenzene are in 250 parts of water and 12 parts of 30% sodium hydroxide solution dissolved and at 400 with a solution of 22.4 parts of crystallized cobalt sulfate, 6.8 parts of crystallized aluminum sulfate, 7,
5 parts of tartaric acid and 50 parts of 30% sodium hydroxide solution are added and the mixture is heated to <B> 70-800 </B> for some time. A further 15 parts of sodium hydroxide solution are then added, the dye solution is filtered to remove any undissolved material and the filtrate is neutralized with dilute formic acid. The precipitated dye is filtered off, washed out and dried at a moderate temperature.
