Description

Verfahren zur Darstellung von -Küpenfarbstoffen. In der Patentschrift 3659o2 und ihren "Zusatzpatenten werden Kondensationsprodukte beschrieben, welche entstehen, wenn man p-Oxyphenazine oder Naphthsultam-3-4-phenazine mit 2-Chlor-i - 4-chinonen oder ihren Substitutionsprodukten bzw. mit Mono-oder Dichlor-4-Naphthsultamchinon umsetzt.Process for the preparation of vat dyes. In the patent specification 3659o2 and their "additional patents describe condensation products, which arise when one p-oxyphenazine or naphthsultam-3-4-phenazine with 2-chloro-i - 4-quinones or their substitution products or with mono- or dichloro-4-naphthsultamquinone implements.

Es wurde nun die Beobachtung gemacht, (laß die Oxyphenazine und die Naphthsultamphenazine überraschenderweise auch mit halogenfreien i - 4-Chinonen unter Bildung wertvoller Kondensationsprodukte in Reaktion treten. Die so erhaltenen Verbindungen stellen oft zum Teil noch Reduktionsprodukte dar und können durch geeignete Oxydation in die Endfarbstoffe übergeführt werden.The observation was now made, (leave the oxyphenazines and the Surprisingly, naphthsultamphenazines also with halogen-free i - 4-quinones react with the formation of valuable condensation products. The so obtained Compounds are often partly still reduction products and can be replaced by suitable Oxidation are converted into the final dyes.

Beispiele. i. 34 Teile Clilornaphthsultatn-3 - 4-phenazin ergeben, mit 17 Teilen i .4-Naphthochinon in 4oo Teilen Nitrobenzol erhitzt, ein in dunkelbraunen Nadeln kristallisiertes Produkt. Die hiermit auf Wolle und Baumwolle in der Küpe erzeugten Farbtöne sind gelbbraun bis gelbgrün. Wird das Kondensationsprodukt vor dem Auffärben einer alkalischen Oxydation unterworfen, z. B. mit Chlorlauge, so erhält man aus der Küpe schöne gelbgrüne Farbtöne, die viel grünstichiger sind als die Färbungen des ähnlichen Kondensationsproduktes aus Naphthsultam-3 - 4-phenazin mit 2 - 3-Dichlornaphthochinon dargestellt nach Patent 368172. Auffallend ist es, daß sich das 2-Chlornaphthsultam-3 - 4-phenazin mit 2 - 3-Dichlornaphthochinon auch nach den Bedingungen der genannten Patentschriften (Zusatz von metallischem Kupfer und wasserfreiem Natriumacetat) nicht umsetzen läßt.Examples. i. 34 parts of clilornaphthsultatn-3 - 4-phenazine give heated with 17 parts of i .4-naphthoquinone in 400 parts of nitrobenzene, one in dark brown Needles crystallized product. Herewith on wool and cotton in the vat The colors produced are yellow-brown to yellow-green. Will the condensation product before subjected to the coloring of an alkaline oxidation, z. B. with sodium chloride, so you get beautiful yellow-green shades from the vat, which are much greener than the colors of the similar condensation product from naphthsultam-3 - 4-phenazine with 2 - 3-dichloronaphthoquinone represented according to patent 368172. It is striking that that the 2-chloronaphthsultam-3 - 4-phenazine with 2 - 3-dichloronaphthoquinone also according to the conditions of the patents mentioned (addition of metallic copper and anhydrous sodium acetate) does not react.

2. 3o Teile Naphthsultam-3 - 4-phenazin und ii Teile Benzochinon werden in Nitrobenzol 15 Minuten zum Sieden erhitzt. Das ausgeschiedene Kondensationsprodukt stellt einen in rötlichbraunen Prismen kristallisierenden Körper dar, der aus olivfarbener Küpe Wolle nach Verhängen in khakifarbenen Tönen färbt. Durch Behandeln des vorgenannten Kondensationsproduktes mit Chlorlauge erhält man eine gelbe Farbstoffpaste, die sich beispielsweise für die Zwecke der Lackindttstr ie sehr gut eignet.2. 3o parts Naphthsultam-3 - 4-phenazine and ii benzoquinone parts are heated in nitrobenzene 1 5 minutes to boiling. The precipitated condensation product represents a body crystallizing in reddish-brown prisms, which dyes wool from olive-colored vats in khaki tones after hanging. By treating the abovementioned condensation product with sodium chloride solution, a yellow dye paste is obtained which is very suitable, for example, for the purposes of paint industry.

3. 123 Teile i-Oxynaphthalin-3 - 4-phenazin und 54 Teile Benzochinon werden bis zur Beendigung der Kondensation in --3 ooo Teilen Nitrobenzol auf 14o bis i5o° erhitzt. Das in grünen Nadeln kristallisierende Kondensationsprodukt färbt aus der rotbraunen Küpe die- tierische und pflanzliche Faser in schönen grünen Tönen von bemerkenswerten Echtheitseigenschaften. In der gleichen Weise wie in Beispiel 2 läßt sich auch das so erhaltene Kondensationsprodukt mit Chlorlauge in eine gelbe Farbstoffpaste umwandeln.3. 123 parts of i-oxynaphthalene-3-4-phenazine and 54 parts of benzoquinone until the end of the condensation in --3,000 parts of nitrobenzene to 14o heated to 150 °. The color of the condensation product, which crystallizes in green needles from the red-brown vat die- animal and vegetable fibers in beautiful green tones of remarkable fastness properties. In the same way as in example 2, the condensation product thus obtained can also be converted into a yellow one with sodium chloride solution Convert dye paste.
