Description

Verfahren zur Darstellung von Wollfarbstoffen der Antrachinonreihe 'Zusatz zum Patent 414865 Durch das Hauptpatent 414 ä 65 ist ein Verfahren zur Darstellung von sauren Wollfarbstoffen geschützt. Es besteht darin, daß man Amino- bzw. Alkylaminodianthrachinonylamine mit sulfierenden Mitteln behandelt. Man erhält so Farbstoffe von dunkelblauen bis grünlichgrauen Tönen, welche hervorragende Echtheitseigenschaften besitzen.Process for the preparation of wool dyes of the antraquinone series 'Addition to patent 414865 by the main patent 414 ä 65 is a method of representation protected from acidic wool dyes. It consists in having amino or alkylaminodianthraquinonylamines treated with sulphurizing agents. This gives dyes from dark blue to greenish-gray tones, which have excellent fastness properties.

Es wurde nun gefunden, :daß man zu Farbstoffen gelangen kann, welche die gleichen wertvollen Färbeeigenschaften wie die Produkte des Hauptpatents, insbesondere auch ihre Lichtechtheit besitzen, wenn man a-a,'-Dianthrachinonylamin selbst mit sulfierenden Mitteln unter solchen Bedingungen behandelt; daß wohl Sulfierung, jedoch keine Oxydation eintritt.It has now been found: that you can get to dyes, which the same valuable coloring properties as the products of the main patent, in particular also have their lightfastness if one uses a-a, '- dianthraquinonylamine itself sulfating agents treated under such conditions; that probably sulfation, however no oxidation occurs.

Dieses Resultat war nicht vorauszusehen. Die Farbstoffe des Hauptpatents, enthalten auxochrome Gruppen, welche für Charakter und Eigenschaften der Farbstoffe wesentlich sind. Im vorliegenden Falle sind solche Gruppen nicht vorhanden. Trotzdem erhält man kräftige Farbstoffe von gleichen vorzüglichen Echtheitseigenschaften, deren Nuancen aber nach dem Verfahren des Hauptpatents nicht erhältlich sind. Auch aus der deutschen Pa-Lentschrift i7¢ 699 war nicht zu entnehmen, daß es möglich sein würde, a-a'-Dianthrachinonylamin nach dem vorliegenden Verfahren in reine Sulfosäuren überzuführen, da das nach obiger Patentschrift durch Sulfierung des a . (3'-Dianthrachinonylamins erhaltbare Produkt ein Gemisch von wahrscheinlich Sulfos,äuren derselben und Oxydationsprodukten der letzteren darstellt.This result could not be foreseen. The dyes of the main patent contain auxochromic groups, which are essential for the character and properties of the dyes. In the present case, there are no such groups. In spite of this, strong dyes with the same excellent fastness properties are obtained, the nuances of which, however, cannot be obtained by the process of the main patent. Also from the German Pa-Lentschrift 17 [ 699 ] it was not to be inferred that it would be possible to convert a-a'-dianthraquinonylamine into pure sulfonic acids by the present process, since according to the above patent by sulfonation of the a. (3'-Dianthraquinonylamine is a mixture of probably sulfonic acids, and oxidation products of the latter.

Beispiel -Eine Auflösung von io Gewichtsteilen i # i'-Dianthrachinonylamn in ioo Gewichtsteilen Oleum von etwa 15 % S03-Gehalt wird kurze Zeit auf 95 bis ioo° erhitzt, bis eine Probe sich in heißem Wasser vollständig mit gelbbrauner Farbe löst. Nach dem Erkalten wird die Schmelze ohne K'ü'hlung in 6oo Gewichtsteile Wasser eingerührt und bei Siedetemperatur allmählich noch so viel gesättigte Kochsalzlösung zugegeben, bis der Farbstoff in einer Probe beim Abkühlen vollständig ausfällt. Nach dem Erkalten wirb das kristallinisch abgeschiedene Produkt auf :ein Filter gebracht und mit verdünnter Salz- Lösung bis zur neutralen Reaktion des Filtrats ausgewaschen.EXAMPLE A dissolution of 10 parts by weight of i # i'-dianthraquinonylamine in 100 parts by weight of oleum with about 15 % SO3 content is briefly heated to 95 to 100 ° until a sample dissolves completely in hot water with a yellow-brown color. After cooling, the melt is stirred into 600 parts by weight of water without cooling and enough saturated sodium chloride solution is gradually added at the boiling point until the dye completely precipitates in a sample on cooling. After cooling, the crystalline precipitated product is swirled up: put on a filter and washed out with dilute salt solution until the filtrate reacts neutral.

Auf Wolle zieht der neue Farbstoff aus saurem Bade in kräftigen, gelblichbraunen Tönen, die auf Chrombeizen sowie durch Nachchromieren nicht verändert werden und sehr gut licht-, walk- und karbonisierecht sind.On wool, the new dye from an acid bath takes on a strong, yellowish-brown color Tones that are not changed on chrome stains or by re-chrome plating and are very light, milled and carbonised.

Der Farbstoff enthält zwei Sulfogruppen in 4 # 4'- Stellung. Diese lassen sich in wwäBriger Lösung durch Brom ersetzen, wodurch das bekannte q. # 4'-Dibrom- i # i'-dianthrachinonylamin (Monatshefte f. Chemie Bd.35, Seite 113 5) entsteht.The dye contains two sulfo groups in the 4 # 4 'position. These can be replaced by bromine in aqueous solution, whereby the well-known q. # 4'-dibromo i # i'-dianthraquinonylamine (monthly journals for chemistry, vol. 35, page 113 5) arises.

Durch vorsichtiges Sulfieren, z. B. mittels Oleum von 25 % S03-Gehalt bei -etwa 3o°, läßt sich auch eine Monosulfosäure des i # i'-Dianthrachinonylamins erhalten, welche Wolle kräftig braunrot färbt.By careful sulfonation, e.g. B. by means of oleum with 25 % SO3 content at -about 30 °, a monosulfonic acid of i # i'-dianthraquinonylamine can also be obtained, which dyes wool a strong brown-red.
