Description
<B>Zusatzpatent</B> zum Hauptpatent Nr. 275439. verfahren zur Herstellung eines Küpenfarbstoffes. Es wurde gefunden, dass man zu einem wertvollen Küpenfarbstoff gelangt, wenn man zwei Mol 1-Amino-5-(2'-fluor-5'-chlorbenzoyl- amino)-anthrachinon mit einem Mol eines den Rest der Azodiphenyldicarbonsäure der Formel
EMI0001.0007
abgebenden Mittels umsetzt. Der neue Farbstoff färbt Baumwolle aus bordeauxroter Hydrosulfitküpe in goldgelben Tönen von hervorragender Lichtechtheit.
Als Mittel, welche den Azodiphenyldicar- bonsäurerest abgeben, kommen z. B. funktio nelle Derivate der oben genannten Säure, ins besondere die Halogenide dieser Säure und unter diesen vor allem das Dichlorid in Be tracht.
Die Umsetzung des 1-Amino-5-(2'-fluor-5'- ehlorbenzoylamino) -anthraehinons mit dem Acylierungsmittel kann nach allgemein be kannten Methoden vorgenommen werden. Zweckmässig lässt man die Ausgangsstoffe in einem indifferenten Lösungs- bzw. Vertei lungsmittel miteinander reagieren.
Da die Re aktion in der Regel bei erhöhter Temperatur leicht vor sich geht, wählt man vorteilhaft solche Lösungsmittel, die einen relativ hohen Siedepunkt besitzen, wie Chlorbenzol, o-Di- ehlorbenzol, Trichlorbenzol, Nitrobenzol oder Naphthalin, und führt die Reaktion ganz oder mindestens zum Teil bei hoher Temperatur, z. B. beim Siedepunkt der betreffenden Lö sungsmittel, durch.
Beispiel: Eine Mischung von 1,55 Teilen Azo- diphenyldiearbonsäure, 6 Volumteilen Thionyl- ehlorid, 90 Volumteilen Trichlorbenzol und 0,05 Teilen Pyridin, wird 30 Minuten bei 800, und 30 Minuten lang bei 120 gerührt und dann zum Sieden erhitzt, wobei das Thionyl- chlorid und etwas Trichlorbenzol abdestilliert wird.
Man lässt die Lösung auf 100 ab kühlen und setzt der Lösung 3 Teile 1-Amino- 5- (2'-fluor-5'-chlorbenzoylamino)-anthrachinon zu und erhitzt 2 Stunden auf 200 bis 2.10 . Nach dem Abkühlen auf etwa 120 wird der Farbstoff abfiltriert und wie üblich aufge arbeitet.
<B> Additional patent </B> to main patent no. 275439. Process for the production of a vat dye. It has been found that a valuable vat dye is obtained if two moles of 1-amino-5- (2'-fluoro-5'-chlorobenzoyl-amino) -anthraquinone are mixed with one mole of the remainder of the azodiphenyldicarboxylic acid of the formula
EMI0001.0007
releasing agent implements. The new dye dyes cotton from a burgundy hydrosulfite vat in golden-yellow shades of excellent lightfastness.
As agents which release the azodiphenyldicarboxylic acid residue, z. B. func tional derivatives of the acid mentioned above, in particular the halides of this acid and, among these, especially the dichloride in Be tracht.
The reaction of the 1-amino-5- (2'-fluoro-5'-ehlorbenzoylamino) -anthraehinons with the acylating agent can be carried out according to generally known methods. The starting materials are expediently allowed to react with one another in an inert solvent or distributing agent.
Since the reaction usually takes place easily at elevated temperature, it is advantageous to choose solvents which have a relatively high boiling point, such as chlorobenzene, o-di-chlorobenzene, trichlorobenzene, nitrobenzene or naphthalene, and carry out the reaction entirely or at least partly at high temperature, e.g. B. at the boiling point of the relevant Lö solvent by.
Example: A mixture of 1.55 parts of azodiphenyl diacid, 6 parts by volume of thionyl chloride, 90 parts by volume of trichlorobenzene and 0.05 part of pyridine is stirred for 30 minutes at 800 and 30 minutes at 120 and then heated to the boil, the Thionyl chloride and some trichlorobenzene is distilled off.
The solution is allowed to cool to 100 and 3 parts of 1-amino-5- (2'-fluoro-5'-chlorobenzoylamino) -anthraquinone are added to the solution and the mixture is heated to 200-2.10 for 2 hours. After cooling to about 120, the dye is filtered off and worked up as usual.
