EMI2.1
Farbstoff heiss gewaschen, er gelangt am besten in Teigform zur Verwendung.
In trockenem Zustande bildet er ein dunkelviolettes Pulver, das beim Reiben Kupferglanz annimmt ; in verdünnten Sauren und Alkalien ist er unlöslich ; in konzentrierter Schwefelsäure löst er sich mit trüb-violetter Farbe ; in organischen Lösungsmitteln schwer löslich, lässt er sich doch aus kochendem Chinolin in feinen Nadeln krystallisieren und löst sich alsdann in konzentrierter Schwefelsäure mit rein violetter Farbe. Mit alkalischer Hydrosulfit. 1ösung liefert der Farbstoff beim Erwärmen eine prachtvoll fuchsinrot-fluores-

Analoge Farbstoffe werden erhalten'durch Verschmelzen der übrigen nach dem Verfahren der obgenannten Patentschrift @ erhältlichen Benzanthronderivate mit kaustischen ; Alkalien.
B e i s p i e l IV. 10 g, Benznaphtanthron werden in 30 g festem Ätzalkali, gelöst in 30 m3 absolutem Alkohol, während einer Viertelstunde auf 150 C und : hierauf eine weitere Viertelstunde auf 165 -170 C erhitzt. Die Schmelze wird mit Wasser ausgekocht, der Rückstand als Paste zum Färben verwendet. Ausbeute 90%. Mit Hydrosulfit und Natron gefärbt, erhält lah auf Baumwolle ein rötliches Blau von hervorragender Chlor- pohtheit,

EMI2.1
Dye washed hot, it is best used in dough form.
When dry it forms a dark violet powder which, when rubbed, takes on a copper luster; it is insoluble in dilute acids and alkalis; in concentrated sulfuric acid it dissolves with a cloudy violet color; Hardly soluble in organic solvents, since it can be crystallized in fine needles from boiling quinoline and then dissolves in concentrated sulfuric acid with a purely violet color. With alkaline hydrosulfite. When heated, the dye delivers a splendid fuchsin-red fluorescent
EMI2.2
Analogous dyes are obtained by fusing the other benzanthrone derivatives obtainable by the process of the above-mentioned patent specification with caustic; Alkalis.
Example IV. 10 g of benznaphtanthrone are heated in 30 g of solid caustic alkali, dissolved in 30 m3 of absolute alcohol, for a quarter of an hour to 150 ° C and then for a further quarter of an hour to 165-170 ° C. The melt is boiled with water, the residue used as a paste for coloring. Yield 90%. Dyed with hydrosulphite and baking soda, on cotton it takes on a reddish blue of excellent chlorine-pithiness,
