Description
Verfahren zur Herstellung eines Nüpenfarbstoffes. Nach dem Verfahren des Hauptpatentes wird durch Erhitzen von 1-Amino-2-methyl- a.nthrachinon und Schwefel unter Zusatz von p-Phenylendiamin ein violetter Küpenfarb- stoff erhalten.
Es wurde gefunden, dass der gleiche Farb stoff entsteht, wenn man statt des 1-Amino- 2-methylantlirachinons den 1-Aminoanthra- chinon-2-aldehyd verwendet.
Da hierbei i.n- termendiär Azomethinverbindungen entste hen, kann man vorteilhaft auch in der Weise verfahren, dass man zunächst aus 1-Amino- anthrachinon-2-aIdehyd und p-Phenylendi- amin durch Erhitzen für sich oder in einem geeigneten Lösungsmittel die Azomethinver- bindung herstellt und diese der Schweflung unterwirft.
Der Zusatz von hochsiedenden Verdünnungsmitteln, wie Naphtalin, sowie von Katalysatoren, wie Jod, Aluminium chlorid und ähnliche erleichert die Farb- stoffbildung und bewirkt die Bildung beson ders reiner Produkte.
Behandelt man die aus 1-Aminoanthrachinon-2-aldehyd und p-Phe- nylendiamin erhältliche Azomethinverbin- dung oder die entsprechende Mischung der beiden Komponenten mit Schwefel, so wird ein violetter Küpenfarbstoff erhalten, der in allen seinen Eigenschaften mit dem Farb stoff des Hauptpatentes übereinstimmt.
<I>Beispiel:</I> 10 kg der durch Kondensation von 1- Aminoanthrachinon-2-aldehyd und p-Pheuyl- endiamin erhaltenen Azomethinverbindung (bezw. ein Gemisch von 9 kg 1-Aminoanthra- chinon-2-aldehyd und 2 kg p-Phenylendi- amih) werden mit 125 kg Naphtalin und 30 kg Schwefel unter Zusatz von 0,3 kg Jod acht Stunden auf etwa 220' erhitzt.
Der Farbstoff wird durch Zusatz von Naphta zu der heissen Schmelze in üblicher Weise ab geschieden und dann durch Behandeln mit kochendem Nitrobenzol gereinigt werden. Der erhaltene Farbstoff löst sich in konzentrier ter Schwefelsäure mit braunoliver Farbe, die durch Zusatz von Paraformaldehyd in Grün blau übergeht. Die mit Hydrosulfit und Lauge erhältliche Küpe ist violett gefärbt und liefert auf Baumwolle violette Nuancen von sehr guter Wasch-, Chlor- und Licht- echtheit. Der Farbstoff ist also identisch mit dem Farbstoff des Hauptpatentes.
Process for the production of a pebble dye. According to the process of the main patent, a violet vat dye is obtained by heating 1-amino-2-methyl-a.nthraquinone and sulfur with the addition of p-phenylenediamine.
It has been found that the same dye is produced if 1-aminoanthraquinone-2-aldehyde is used instead of 1-amino-2-methylantlirachinons.
Since azomethine compounds are formed in an intermediate manner, it is also advantageous to proceed in such a way that the azomethine compound is first obtained from 1-aminoanthraquinone-2-aldehyde and p-phenylenediamine by heating alone or in a suitable solvent manufactures and subjects them to sulphurization.
The addition of high-boiling diluents such as naphthalene as well as catalysts such as iodine, aluminum chloride and the like facilitates the formation of dyes and results in the formation of particularly pure products.
If the azomethine compound obtainable from 1-aminoanthraquinone-2-aldehyde and p-phenylenediamine or the corresponding mixture of the two components is treated with sulfur, a violet vat dye is obtained which corresponds in all its properties to the dye of the main patent .
<I> Example: </I> 10 kg of the azomethine compound obtained by condensation of 1-aminoanthraquinone-2-aldehyde and p-phenylenediamine (or a mixture of 9 kg of 1-aminoanthraquinone-2-aldehyde and 2 kg p-phenylenediamine) are heated for eight hours to about 220 minutes with 125 kg of naphthalene and 30 kg of sulfur with the addition of 0.3 kg of iodine.
The dye is deposited in the usual way by adding naphtha to the hot melt and then purified by treatment with boiling nitrobenzene. The dye obtained dissolves in concentrated sulfuric acid with an olive-brown color which changes to green-blue when paraformaldehyde is added. The vat available with hydrosulphite and lye is colored violet and provides violet shades of very good wash, chlorine and lightfastness on cotton. The dye is therefore identical to the dye of the main patent.
