In der Patentschrift 114266 ist ein Verfahren zur Darstellung eines blauvioletten Farbstoffs beschrieben, das darin besteht, dafs man das Naphtazarinzwischenproduct mit Schwefelalkalien erhitzt.In patent specification 114266 is a method for the representation of a blue-violet dye, which consists in the fact that one Naphtazarin intermediate heated with sulfur alkalis.
Einen Farbstoff von wesentlich den gleichen Eigenschaften, aber in reiner blauvioletten Nuancen färbend, erhält man, indem man das Naphtazarinzwischenproduct bei Gegenwart von Chlorzink mit Schwefelalkalien erhitzt.A dye with much the same properties, but in a purer blue-violet color Coloring nuances are obtained by adding the naphtazarin intermediate in the presence of Chlorine-zinc heated with alkaline sulfur.
Man kann für die Darstellung des neuen Farbstoffs direct das chlorzinkhaltige Zwischenproduct verwenden, welches man nach dem Verfahreh der Patentschrift 111683 durch Fällung der verdünnten Naphtazarinschmelze mit Chlorzink erhält.The intermediate product containing zinc chloride can be used for the preparation of the new dye use which one after the procedure of the patent 111683 by Precipitation of the diluted naphtazarin melt with zinc chloride is obtained.
Beispiel: Man erhizt das Gemenge von 1 kg Naphtazarinzwischenproduct, 150 g Chlorzink, ι kg Schwefel und 5 kg kryst. Schwefelnatrium mehrere Stunden auf 150 bis i8o°, bis eine Zunahme der Farbintensität nicht mehr zu bemerken ist. Die Schmelze wird sodann in Wasser gelöst, die Lösung filtrirt und zur Trockne verdampft.Example: The mixture of 1 kg of naphtazarin intermediate product, 150 g of zinc chloride is heated, ι kg of sulfur and 5 kg of kryst. Sodium sulphide for several hours at 150 to 180 degrees, to one The increase in color intensity is no longer noticeable. The melt is then in Dissolved water, the solution filtered and evaporated to dryness.
Der erhaltene Farbstoff ist ein dunkles Pulver, das sich in Wasser, Schwefelalkalien, Aetzalkalien oder Alkalicarbonaten leicht mit dunkelblauer Farbe auflöst. Durch Säure wird die Lösung gefällt. Der Farbstoff färbt ungeheizte Baumwolle sehr waschecht blauviolett an.The dye obtained is a dark powder that dissolves in water, alkaline sulfur, alkaline acid or alkali carbonates easily dissolve with dark blue color. Acid makes the Solution like. The dye stains unheated cotton in a very washfast blue-violet.
Durch Nachbehandlung mit Kupfersulfat werden die directen Färbungen in sehr kräftige schwarze Nuancen übergeführt. Das neue Product ist vor allen bisher in den Handel gebrachten Schwefelfarbstoffen dadurch ausgezeichnet, dafs die Färbungen während des Färbeprocesses unempfindlich gegen den Luftsauerstoff sind. Die umständlichen Vorkehrungen, die bei den Handelsproducten erforderlich sind, um Unegalitäten zu vermeiden, fallen bei dem neuen Farbstoff weg.After treatment with copper sulphate, the direct colorations become very strong black nuances transferred. The new product is above all brought onto the market so far Sulfur dyes are distinguished by the fact that the dyeings are insensitive to atmospheric oxygen during the dyeing process are. The cumbersome precautions that are required with commercial products to avoid unevenness are eliminated gone with the new dye.
