Description

Verfahren zur Herstellung von Küpenfarbstoffen. Zusatz zum Patent 395691. Durch das Hauptpatent 395691 ist ein Verfahren zur Darstellung neuer Küpenfarbstoffe durch Kondensation von Oxydationsprodukten des Dibenzanthrons mit aromatischen Verbindungen, die eine oder mehrere Trihalogenmethylgruppen enthalten, geschützt.Process for the production of vat dyes. Addition to the patent 395691. The main patent 395691 is a process for the preparation of new vat dyes by condensation of oxidation products of dibenzanthrone with aromatic compounds, containing one or more trihalomethyl groups, protected.

Es wurde nun gefunden, daß man die Eigenschaften dieser Farbstoffe verbessern kann, indem man sie einer Nachbehandlung mit halogenierenden Mitteln unterzieht. Die so erhaltenen neuen Farbstoffe unterscheiden sich von den nicht behandelten Farbstoffen durch größere Reinheit und in manchen Fällen auch durch eine Verschiebung der Nuance. Man kann die Nachbehandlung mit halogenierenden Mitteln bei An- und Abwesenheit von; Verdünnungsmitteln oder von Überträgern vornehmen.It has now been found that the properties of these dyes can be improved can be improved by subjecting them to a post-treatment with halogenating agents undergoes. The new dyes thus obtained do not differ from them treated dyes by greater purity and in some cases by a shift in nuance. You can post-treatment with halogenating agents in the presence and absence of; Make thinners or carriers.

B eispiel.Example.

5 Teile des gemäß Beispiel I des Patents 395691 erhaltenen Farbstoffes werden mit ioo Teilen Nitrobenzol angeschlämmt. In das Gemisch läßt man unter Rühren bei etwa 9o° langsam io Teile Sulfurylchlorid eintropfen, worauf man die Temperatur noch. einige Stunden auf derselben Höhe hält. Nach dem Erkalten saugt man den abgeschiedenen Farbstoff ab und arbeitet ihn in der üblichen Weise auf. Er färbt Baumwolle aus der Küpe in. schönen türkisblauen Tönen an, welche leuchtender als die Färbungen des nicht behandelten Farbstoffes sind und sich durch eine Verschiebung der Nuance nach Grün auszeichnen.5 parts of the dye obtained according to Example I of patent 395691 are slurried with 100 parts of nitrobenzene. The mixture is left with stirring slowly drop in 10 parts of sulfuryl chloride at about 90 °, whereupon the temperature is increased still. holds at the same level for a few hours. After cooling down, you vacuum the separated Dye off and work it up in the usual way. He dyes cotton the vat in beautiful turquoise-blue tones, which are brighter than the colorations of the untreated dye and are characterized by a shift in shade marked according to green.

Setzt man vor der Behandlung mit Sulfurylchlorid dem Gemisch o,2 Teile Jod zu, so entsteht ein Farbstoff, der noch etwas klarere Färbungen gibt. Ähnlich arbeitet man bei Verwendung der anderen nach dem Patent 395691 erhältlichen Farbstoffe und anderer halogenierender Mittel.If the mixture is added before treatment with sulfuryl chloride, 0.2 parts If iodine is added, a dye is created that gives a somewhat clearer color. Similar one works using the other dyes obtainable according to patent 395691 and other halogenating agents.
