Description
Verfahren zur Herstellung eines stickstoffhaltigen Kondensationsproduktes. Es wurde gefunden, dass ein stickstoff haltiges Kondensationsprodukt erhalten wer den kann, wenn 1.2-Phthaloyl-4-bromcai-ba- zol mit 1.5-Monobenzoyldiainirioanthrachinon zur Umsetzung gebracht und das gebildete Produkt mit sauren kondensierenden Mitteln behandelt wird.
Das erhaltene stickstoffhaltige Konden sationsprodukt stellt ein braunes Pulver dar, das sich in konzentrierter Schwefelsäure mit blaugrauer Farbe löst und Baumwolle aus rotbrauner Küpe in kräftigen braunen Tönen von sehr guter Echtheit färbt.
<I>Beispiel:</I> 12 Teile 1.2-Plithaloyl-4-bromcarbazol, 12 Teile 1.5-Monoberizoyldiaininoanthrachirion, 10 Teile wasserfreies Natriumazetat, 1 Teil Kupferazetat, 200 Teile Naphthalin werden 10-20 Stunden unter Rühren gekocht; man lässt etwas abkühlen, verdünnt mit 200 Teilen Chlorbenzol und filtriert das Unisetznngs- produkt noch warm ab. Durch Behandeln mit verdünnten Mineralsäuren entfernt man dar aus die anorganischen Bestandteile.
Es kri stallisiert in dunkelbraunen Nädelchen, die sich in konzentrierter Schwefelsäure mit vio letter Farbe lösen und Baumwolle aus rot brauner Küpe in kräftigen bordeauxroten Tönen färben, die gute Echtheitseigenschaften aufweisen.
5 Teile dieses Kondensationsproduktes werden mit 100 Teilen konzentrierterSchwefel- säure so lange bei 40-501 verrübrt, bis die Lösungsfarbe graublau geworden ist. Man giesst auf Eiswasser und saugt das Reaktions produkt ab.
Process for the production of a nitrogen-containing condensation product. It has been found that a nitrogen-containing condensation product can be obtained when 1,2-phthaloyl-4-bromocai-bazole is reacted with 1,5-monobenzoyldiainirioanthraquinone and the product formed is treated with acidic condensing agents.
The nitrogen-containing condensation product obtained is a brown powder which dissolves in concentrated sulfuric acid with a blue-gray color and dyes cotton from a red-brown vat in strong brown shades of very good fastness.
<I> Example: </I> 12 parts of 1,2-plithaloyl-4-bromocarbazole, 12 parts of 1,5-monoberizoyldiaininoanthrachirione, 10 parts of anhydrous sodium acetate, 1 part of copper acetate, 200 parts of naphthalene are boiled for 10-20 hours while stirring; it is allowed to cool somewhat, diluted with 200 parts of chlorobenzene and the product is filtered off while it is still warm. Treatment with dilute mineral acids removes the inorganic constituents from it.
It crystallizes in dark brown needles that dissolve in concentrated sulfuric acid with violet color and dye cotton from a red-brown vat in strong burgundy shades that have good fastness properties.
5 parts of this condensation product are stirred up with 100 parts of concentrated sulfuric acid at 40-501 until the solution color has turned gray-blue. It is poured into ice water and the reaction product is filtered off with suction.
