Description
ι Teil Anthracen-i -g-dicarbonsäureimid, welches z. B. aus Aceanthrenchinonoxim durch Behandeln mit konzentrierter Schwefelsäure erhalten werden kann, wird im Ölbad mit etwa 5 Teilen Alkalihydroxyd und etwas Wasser auf 200 bis 230° kürzere oder längere Zeit bis zur beendeten Farbstoffbildung erhitzt. Nach dem Erkalten wird die Schmelze in Wasser gelöst, das Alkali teilweise neutralisiert und Luft eingeleitet, wobei der grüne Farbstoff in Flocken ausfällt. Natürlich kann man zur Ausfällung des Farbstoffes auch Oxydationsmittel zusetzen. Mit Hydrosulfit löst sich der Farbstoff zu einer kirschroten Küpe. In dieser Küpe färbt sich Baumwolle mit schön rotvioletter Farbe, welche beim Zutritt der Luft in ein prachtvolles, sattes Grün übergeht. ι part of anthracene-i -g-dicarboximide, which z. B. from aceanthrenequinone oxime by treatment with concentrated sulfuric acid can be obtained is in an oil bath with about 5 parts alkali hydroxide and something Water heated to 200 to 230 ° for a shorter or longer time until the dye formation has ended. After cooling, the melt is dissolved in water and the alkali is partially neutralized and air introduced, whereby the green dye precipitates in flakes. Of course you can oxidizing agents are also added to precipitate the dye. Dissolves with hydrosulfite the dye turns into a cherry-red vat. Cotton is also colored in this vat beautiful red-violet color, which turns into a magnificent, rich green when the air enters.
In ähnlicher Weise verfährt man bei Anwendung halogensubstituierter Anthracen-i · 9-dicarbonsäureimide. A similar procedure is followed when using halogen-substituted anthracene-i · 9-dicarboximides.
Paten τ-An Spruch:Godfather τ-An saying:
Verfahren zur Darstellung von Küpenfarbstoffen der Anthracenreihe, darin bestehend, daß man Anthracen-i · 9-dicarbonsäureimid bzw. dessen Halogensubstitutionsprodukte der Alkalischmelze unterwirft und aus der Schmelze, erforderlichenfalls nach dem Verdünnen mit Wasser, den Farbstoff durch Luft oder Zusatz von Oxydationsmitteln ausfällt.Process for the preparation of vat dyes of the anthracene series, consisting of that one anthracene-i · 9-dicarboximide or its halogen substitution products subjected to the alkali melt and from the melt, if necessary after dilution with water, the dye precipitated by air or by the addition of oxidizing agents.
