Description
Verfahren zur Darstellung eines sauren Anthraehinonfarbstof%s. Es wurde gefunden, dass man zu einem sauren Anthrachinonfarbstoff von vorzügli chem Egalisierungsvermögen dadurch ge langt, dass man die 1-Amino-4-bromanthra: ehinon-2-sulfosäure mit p-Aminoplienolgly- koläther zur Reaktion bringt.
<I>Beispiel:</I> 3,8 gr 1-Amino-4-bromanthrachinon-2- sulfosäure werden mit 5 gr p-Aminophenol- glykoläther, 10 gr Soda und wenig einer 1.0%i.-en wässerigen gupfersulfatlösung 30 Minuten in 150 cm' Wasser zum Sieden er hitzt. Die erhaltene, tiefblaue Lösung wird mit Wasser verdünnt, filtriert, der Farbstoff ausgesalzen und getrocknet.
Der Farbstoff kristallisiert in blauen Na deln, ist leicht löslich in Wasser mit grün stichig blauer Farbe. Er liefert gut egalisie rende blaue Färbungen.
Method for preparing an anthraquinone acid dye% s. It has been found that an acidic anthraquinone dye of excellent leveling capacity is obtained by reacting the 1-amino-4-bromoanthra: ehinone-2-sulfonic acid with p-aminoplienol glycol ether.
<I> Example: </I> 3.8 g of 1-amino-4-bromoanthraquinone-2-sulfonic acid are mixed with 5 g of p-aminophenol glycol ether, 10 g of soda and a little 1.0% i.-en aqueous copper sulfate solution for 30 minutes in 150 cm 'of water to boil. The deep blue solution obtained is diluted with water, filtered, the dye is salted out and dried.
The dye crystallizes in blue needles and is easily soluble in water with a green, tinged blue color. It provides well-leveling blue colors.
