Description

Verfahren zur Darstellung von Küpenfarbstoffen der Perylenreihe. Es wurde die überraschende Beobachtung gemacht, daß neue wertvolle Küpenfarbstoffe der Perylenreihe erhalten werden, wenn man die Oxydationsprodukte der Perylenstruktur besitzenden Küpenfarbstoffe mit sauren Kondensationsmitteln, wie z. B. Aluminiumchlorid, Chlorzink usw., in der Hitze behandelt und die entstandenen neuen Umwandlungsprodukte alkyliert. Über die Zusammensetzung dieser neuen Farbstoffe kann zur Zeit noch nichts ausgesagt werden; sie zeichnen sich durch klare schöne Nüance und Echtheit aus.Process for the preparation of vat dyes of the perylene series. It the surprising observation was made that new valuable vat dyes of the perylene series can be obtained by considering the oxidation products of the perylene structure owning vat dyes with acidic condensing agents, such as. B. aluminum chloride, Zinc chloride, etc., treated in the heat and the resulting new transformation products alkylated. At the moment nothing can be said about the composition of these new dyes to be testified; they are characterized by clear, beautiful nuance and authenticity.

Beispiel: to Teile des nach Beispiel 2 des Patents 25937o erhältlichen Oxydationsproduktes von Dibenzanthron werden mit 5o Teilen wasserfreiem Chlorzink unter Rühren auf 31o bis 32o° erhitzt. Nach Beendigung der Reaktion wird -die erkaltete, zerkleinerte Schmelze mit Wasser aufgekocht, abgesaugt und gewaschen. Die noch feuchte Paste wird sodann mit 3oo Teilen Nitrobenzol, 15 Teilen Soda und 15 Teilen p-Tolüolsulfosäureinethylester so lange auf 165 bis r7o° erhitzt, bis die tiefblaue Lösung an Färbung nicht mehr zunimmt, was nach ungefähr 2 Stunden der Fall ist. Aus der heiß abgesaugten Lösung scheidet sich beim Erkalten das Reaktionsprodukt in blauvioletten Kristallen ab, die in trockenem Zustand starken Metallglanz besitzen und sich in konzentrierter Schwefelsäure mit weinroter Farbe auflösen.Example: to parts of that obtainable according to example 2 of patent 25937o The oxidation product of dibenzanthrone is mixed with 50 parts of anhydrous zinc chloride heated to 31o to 32o ° with stirring. After the reaction has ended, the cold, Crushed melt boiled with water, sucked off and washed. The still damp Paste is then made with 300 parts of nitrobenzene, 15 parts of soda and 15 parts of ethyl p-toluenesulfate Heated to 165 to 70 ° until the deep blue solution ceases to be colored increases, which happens after about 2 hours. From the hot suctioned solution When cooling down, the reaction product separates out in blue-violet crystals, which have a strong metallic luster when dry and concentrate in a more concentrated manner Dissolve sulfuric acid with a wine-red color.

Der neue Farbstoff färbt aus violetter Küpe Baumwolle violett. Beim Verhängen erhält man ein klares Blau.The new dye dyes cotton violet from the violet vat. At the When hanging, you get a clear blue.
