Description
Verfahren zur Darstellung eines neuen Farbstoffes der Anthraehinonreihe. Das vorliegende Patent betrifft ein Ver fahren zur Darstellung eines neuen Farb stoffes der Anthrachinonreihe und ist da durch gekennzeichnet, dass man 1,4-Di-(2',4'- dimethyl) - phenylamino - 6 - chloranthrachinon chloriert und die erhaltene Verbindung sul- fiert.
<I>Beispiel:</I> 15 Teile 1,4-Di-(2',4'-dimethyl)-phenyl- amino-6-chloranthrachinon werden in 400 Tei len Chlorbenzol verrührt. Nach Zugabe von 0,2 Teilen Jod werden 10 Teile Sulfuryl- chlorid zugetropft. Man lässt nun bei 40 rühren, bis die Reaktion beendet ist. Das Chlorbenzol wird dann mit Wasserdampf ab geblasen und die Farbbase durch Filtration abgetrennt.
5 Teile der getrockneten Base werden in 15 Teilen Schwefelsäuremonohydrat gelöst, mit 10 Teilen Oleüm 28 % versetzt und so lange bei 40 gerührt, bis eine Probe in Was ser klar löslich ist. Der Farbstoff wird auf übliche Weise, z. B. Eingiessen in Salz lösung, abgetrennt und getrocknet.
Der Farbstoff besitzt die Formel
EMI0001.0025
und färbt Wolle in schönen blauen Tönen.
Process for the preparation of a new dye of the anthraehinone series. The present patent relates to a process for the preparation of a new dye of the anthraquinone series and is characterized by the fact that 1,4-di- (2 ', 4'-dimethyl) - phenylamino - 6 - chloranthraquinone is chlorinated and the compound obtained is sul - celebrated.
<I> Example: </I> 15 parts of 1,4-di- (2 ', 4'-dimethyl) -phenyl-amino-6-chloroanthraquinone are stirred in 400 parts of chlorobenzene. After adding 0.2 part of iodine, 10 parts of sulfuryl chloride are added dropwise. The mixture is now allowed to stir at 40 until the reaction has ended. The chlorobenzene is then blown off with steam and the color base is separated off by filtration.
5 parts of the dried base are dissolved in 15 parts of sulfuric acid monohydrate, 10 parts of 28% oleum are added and the mixture is stirred at 40 until a sample is clearly soluble in what water. The dye is applied in a conventional manner, e.g. B. Pouring into saline solution, separated and dried.
The dye has the formula
EMI0001.0025
and dyes wool in beautiful blue tones.
