Verfahren zur Herstellung von Schwefelfarbstoffen.Process for the production of sulfur dyes.
Patentiert im Deutschen Reiche vom 14. März 1911 ab.Patented in the German Empire on March 14, 1911.
Es wurde gefunden, daß die Indophenolsulfosäuren, welche man durch Kondensation von Nitrosophenol oder dessen Substitutionsprodukten oder durch Oxydation von p-Aminophenol oder dessen Substitutionsprodukten mit den Kondensationsprodukten aus Benzidin und Naphtylaminsulfosäuren erhalten kann, in der Schwefelschmelze zu wertvollen Schwefelfarbstoffen führen.It has been found that the indophenolsulfonic acids, which are obtained by condensation by nitrosophenol or its substitution products or by oxidation of p-aminophenol or its substitution products with the condensation products of benzidine and Naphthylamine sulfonic acids can be obtained in the sulfur melt to form valuable sulfur dyes to lead.
ίο Die diesen neuen Indophenolsulfosäuren zugrunde liegenden Kondensationsprodukte werden durch Verschmelzen von Benzidin einerseits, mit Naphtylaminsulfosäuren (z.B. 1-7-, 1-8-, ι ■ 2-Naphtylaminsulfosäure, 1 · 4 · 8-Naphtylamindisulfosäure und sonstigen) anderseits, mit oder ohne Zusatz eines Lösungsoder Suspensionsmittes, dargestellt, so z. B. in der Weise, daß man 44,6 kg i-Naphtylamin-8-sulfosäure und 55,2 kg Benzidin miteinander erhitzt und die erkaltete Schmelze in fein gepulvertem Zustand durch mehrfache Behandlung mit kochender Sodalösung und Ausfällen der kochenden Lösung mit verdünnter Salzsäure vom beigemengten Benzidin und i-Naph- tylamin-8-sulfosäure befreit.ίο The basis of these new indophenol sulfonic acids lying condensation products are produced by fusing benzidine on the one hand, with naphthylamine sulfonic acids (e.g. 1-7-, 1-8-, ι ■ 2-naphthylamine sulfonic acid, 1x4x8-naphthylamine disulfonic acid and other) on the other hand, with or without the addition of a solvent or suspending agent, shown, e.g. Am the way that you 44.6 kg of i-naphthylamine-8-sulfonic acid and 55.2 kg of benzidine are heated together and the cooled melt in a finely powdered state by multiple treatments with boiling soda solution and precipitation of the boiling solution with dilute hydrochloric acid from the added benzidine and i-naph- tylamine-8-sulfonic acid freed.
Die Herstellung der Indophenolsulfosäuren erfolgt in üblicher Weise durch Zusammenoxydieren von p-Aminophenol oder dessen Substitutionsprodukten mit den vorerwähnten Sulfosäuren; sie stellen in Wasser unlösliche, in verdünnter Natronlauge lösliche Körper dar. Die Schwefelschmelze mittels derselben kann mit Alkalipolysulfid in verschiedenen Verhältnissen mit oder ohne Zusatz eines Verdünnungsmittels (Wasser, Alkohol, Glycerin, Phenol, Kresol usw. bzw. Metallsalzes, z. B. eines Kupfersalzes) bei wechselnden Temperaturen ausgeführt werden. Der Kupferzusatz erweist sich als besonders vorteilhaft zur Erzeugung grüner Farbstoffe, während ohne Kupferzusatz mehr blaue bis grünblaue Farbstoffe erhalten werden.The indophenol sulfonic acids are prepared in the usual way by oxidizing p-aminophenol or its substitution products with the aforementioned sulfonic acids; They represent bodies that are insoluble in water and soluble in dilute sodium hydroxide solution. The molten sulfur can be mixed with alkali polysulphide in various proportions with or without the addition of a diluent (water, alcohol, glycerine, phenol, cresol, etc. or a metal salt, e.g. Copper salt) at changing temperatures. The addition of copper has proven particularly advantageous for the generation of green dyes, whereas without Kup erzusatz f more blue to green can be obtained blue dyes.
100 kg der durch Zusammenoxydieren von p-Aminophenol mit dem Kondensationsprodukt aus Benzidin und 1 · 8-N aphtylaminsulfosäure erhaltenen Rohindophenolsulfosäure werden in eine wäßrige Polysulfidlösung, bestehend aus 800 kg Schwefelnatrium, 500 kg Schwefel, eingetragen und mit oder ohne Zusatz von etwa 50 kg Kupfervitriol ungefähr 30 Stunden am Rückflußkühler zum Kochen erhitzt. Die Schmelze ist dann beendet, wenn sich in der Schmelze keine Indophenolsulfosäure mehr nachweisen läßt.100 kg by oxidizing p-aminophenol together with the condensation product Crude indophenol sulfonic acid obtained from benzidine and 1 × 8-N aphtylaminsulfosäure are in an aqueous polysulphide solution consisting of 800 kg of sodium sulfur, 500 kg of sulfur, entered and with or without the addition of about 50 kg of vitriol for about 30 hours The reflux condenser heated to the boil. The melt is ended when the Indophenolsulfonic acid can no longer be detected in the melt.
Die Isolierung des Farbstoffes erfolgt nach den bei Schwefelfarbstofien üblichen Methoden, z. B. durch Auslaugen, Ausblasen oder Ausfällen mit Säure, Abpressen und Trocknen.The dye is isolated by the methods customary for sulfur dyes, z. B. by leaching, blowing or precipitation with acid, pressing and drying.
Der so erhaltene Farbstoff stellt in reinem Zustande ein metallglänzendes, grünblaues Pulver dar, welches sich in Schwefelnatrium mit gelblicher Farbe leicht löst und daraus Baumwolle in schönen klaren, grünen Tönen anfärbt, die durch besondere Waschechtheit gegenüber. den Farbstoffen der Patentschrift 162156 ausgezeichnet sind. Auch die Lichtechtheit ist eine ganz hervorragende.In its pure state, the dye obtained in this way is a shiny metal, green-blue powder which is dissolved in sodium sulphide easily dissolves yellowish color and dyes cotton in beautiful clear, green tones from it, those due to special washfastness. awarded the dyes of patent specification 162156 are. The lightfastness is also very good.
Auf dieselbe Weise lassen sich auch die übrigen Schwefelfarbstoffe dieser neuen Klasse herstellen. Dieselben zeichnen sich durchThe other sulfur dyes of this new class can also be used in the same way produce. The same are characterized by
ihre leichte Löslichkeit bei sehr guter Waschechtheit aus.their easy solubility and very good wash fastness.
