Description
Verfahren zur Darstellung eines neuen, wasserlöslichen Farbstoffes der Anthrachinonreihe. Das vorliegende Patent betrifft ein Ver fahren zur Darstellung eines neuen, wasser löslichen Farbstoffes der Anthrachinonreihe und ist dadurch gekennzeichnet, dass man 1 Alol 1.4.5.8-Tetraaminoanthrachinon, 2 Mol Phenol und 2 Mol Formaldehyd aufeinander einwirken lässt und das erhaltene Produkt sulfoniert.
Der neue Farbstoff enthält zwei Sulfo- gruppen und löst sich in kaltem Wasser mit blaugrauer, in heissem Wasser mit blauer und in konzentrierter Schwefelsäure mit gelber Farbe. Er soll zum Färben von Acetatseide, acetylierter Baumwolle und von Acetylcellu- losefolien verwendet werden. Das Färbegut wird in wässeriger Lösung blau gefärbt.
Beispiel.: 20 kg 1.4.5.8-Tetraaminoanthrachinon und 100 kg Phenol werden bei 100 o C verrührt. Innert einer Stunde lässt man 25 kg Form aldehyd von 40 Vol.-% einlaufen, rührt kurze Zeit weiter und drückt die Schmelze in a1- kalisches Salzwasser. Das ausgefallene Kon densationsprodukt wird abfiltriert, in Wasser aufgenommen und mit Schwefelsäure neutral gestellt. Man filtriert, wäscht und trocknet.
Durch Sulfonieren in Schwefelsäuremono- hydrat erhält man einen Farbstoff, der' sich in kaltem Wasser mit blaugrauer, in heissem Wasser mit blauer und in konzentrierter Schwefelsäure mit gelber Farbe löst. Er soll zum Färben von Acetat'seide, acetylierter Baumwolle und von Acetylcellulosefolien ver wendet werden. Das Färbegut wird in wässe riger Lösung blau gefärbt.
Process for the preparation of a new, water-soluble dye of the anthraquinone series. The present patent relates to a process for the preparation of a new, water-soluble dye of the anthraquinone series and is characterized in that 1 Alol 1.4.5.8-Tetraaminoanthraquinone, 2 moles of phenol and 2 moles of formaldehyde are allowed to act on one another and the product obtained is sulfonated.
The new dye contains two sulfo groups and dissolves in cold water with a blue-gray color, in hot water with blue and in concentrated sulfuric acid with a yellow color. It is intended to be used for dyeing acetate silk, acetylated cotton and acetyl cellulose films. The material to be dyed is dyed blue in an aqueous solution.
Example: 20 kg 1.4.5.8-tetraaminoanthraquinone and 100 kg phenol are stirred at 100 o C. 25 kg of formaldehyde of 40% by volume are run in within one hour, stirring is continued for a short time and the melt is pressed into alkaline salt water. The precipitated condensation product is filtered off, taken up in water and neutralized with sulfuric acid. It is filtered, washed and dried.
Sulphonation in sulfuric acid monohydrate gives a dye which dissolves in cold water with a blue-gray color, in hot water with a blue color and in concentrated sulfuric acid with a yellow color. It is said to be used for dyeing acetate silk, acetylated cotton and acetyl cellulose films. The material to be dyed is dyed blue in an aqueous solution.
