Description
Verfahren zur Herstellung eines Farbstoffes der Anthrachinonreilie. Es -wurde gefunden, dass man einen Farb stoff der Anthrachinonreihe erhält, wenn man die Leukoverbindung des 1.4.5.8- Tetraoxyanthraehinons in wässerigem Me dium in Gegenwart von Borsäure mit Am moniak erhitzt, wobei zwei Mol Ammoniak mit einem Mol des obigen Anthrachinonderi- vates kondensieren,
und das so erhaltene Kon densationsprodukt zum Anthraehinonderivat oxydiert.
Der erhaltene Farbstoff bildet ein dunk les Pulver und löst sich in organischen Lö sungsmitteln mit blauer Farbe auf. Er färbt Acetatseide nach geeigneter Verpastung blau. <I>Beispiel:</I> 27 Teile Leuko-l. 4 . ,5 . -8-T-etraoxyanthra- chinon werden als feine Paste in 200 Teilen einer 24 % igen wässerigen Ammoniaklösung mit 20 Teilen krist. Borsäure sechs Stunden auf 80 bis 100 erhitzt, wobei Leuko-1 . 4- dioxy - 5.
8 - diaminoanthrachinon entsteht. Das Produkt wird durch Erhitzen an der Luft oder in Borsäure-Schwefelsäure oxy- diert.
Process for the production of a dye of the anthraquinone range. It was found that a dye of the anthraquinone series is obtained if the leuco compound of 1.4.5.8- Tetraoxyanthraehinons is heated in aqueous medium in the presence of boric acid with ammonia, two moles of ammonia condensing with one mole of the above anthraquinone derivative ,
and the condensation product thus obtained is oxidized to give the anthraquinone derivative.
The dye obtained forms a dark powder and dissolves in organic solvents with a blue color. After suitable pasting, it turns acetate silk blue. <I> Example: </I> 27 parts of Leuko-l. 4th , 5. -8-T-etraoxyanthraquinone are crystallized as a fine paste in 200 parts of a 24% strength aqueous ammonia solution with 20 parts. Boric acid heated to 80 to 100 for six hours, with Leuko-1. 4- dioxy - 5.
8 - diaminoanthraquinone is formed. The product is oxidized by heating in air or in boric acid-sulfuric acid.
