Description

Verfahren zur Darstellung von echten blauen Schwefelfarbstoffen Es wurde gefunden, daB die in dem Patent 445 27o beschriebenen Chinonküpenfarbstoffe, die - man durch Kondensation der Arylaminoderivate von o-Aminoarylmerkaptanen der allgemeinen Formel: oder ihrer Äquivalente mit Arylchinonen und ihren Derivaten, insbesondere ihren Halogensubstitutionsprodukten, erhält und welche wahrscheinlich folgende Zusammensetzung haben (R1 = Aryl, R = H oder Alkyl oder Aralkyl, X = H oder einwertiger Substituent), sulfhydraten, Alkalisulfiden oder Polysulfiden, in sehr- wertvolle blaue Schwefelfarbstoffe übergehen. Dieselben zeichnen sich überraschenderweise durch hervorragende Wasch- und Lichtechtheit aus und übertreffen darin die bisher bekannten blauen Schwefelfarbstoffe, insbesondere diejenigen aus Indophenolen bzw. Leukoindophenolen, die aus Diphenylamin und Nitrosophenolen hergestellt werden, obwohl sie diesen Farbstoffen wahrscheinlich chemisch nahestehen.Process for the preparation of true blue sulfur dyes It has been found that the quinone vat dyes described in patent 445 27o, which - are obtained by condensation of the arylamino derivatives of o-aminoaryl mercaptans of the general formula: or their equivalents with arylquinones and their derivatives, in particular their halogen substitution products, and which probably have the following composition (R1 = aryl, R = H or alkyl or aralkyl, X = H or monovalent substituent), sulfhydrates, alkali sulfides or polysulfides, convert into very valuable blue sulfur dyes. Surprisingly, they are distinguished by excellent washing and lightfastness and in this respect the blue sulfur dyes known to date, in particular those made from indophenols or leucoindophenols, which are produced from diphenylamine and nitrosophenols, although they are probably chemically close to these dyes.

Beispiel 4o kg des nach Beispiel z der Patents 445 27ö erhältlichen Farbstoffs von wahrscheinlich folgender Zusammensetzung: werden in eine Lösung von etwa 25o kg Sprit, 6o kg wasserfreiem Schwefelnatrium und 3o kg Schwefel eingetragen, und das Ganze wird in einem mit Rückflußkühler und Rührwerk versehenen Gefäß etwa 2o bis 40 Stunden erhitzt. Der Sprit wird abdestiRiert, -der Rückstand mit Salzlösung verdünnt, und- der abgeschiedene Farbstoff filtriert, gewaschen und getrocknet. Er färbt Baumwolle im Schwefelnatriumbade oder in der Küpe in reinblauen Tönen von hervorragender Wasch- und Lichtechtheit.Example 40 kg of the dye obtainable according to example z of patent 445 27ö, probably of the following composition: are added to a solution of about 250 kg of fuel, 60 kg of anhydrous sodium sulfur and 30 kg of sulfur, and the whole is heated in a vessel equipped with a reflux condenser and stirrer for about 20 to 40 hours. The fuel is distilled off, -the residue is diluted with salt solution, and- the deposited dye is filtered, washed and dried. It dyes cotton in a sulphurous sodium bath or in the vat in pure blue shades of excellent washing and lightfastness.

In gleicher Weise kann das Verfahren mit anderen Chinonküpenfarbstoffen obiger Art und mit anderen üblichen Schwefelungsmitteln durchgeführt werden. Verwendet man z. B. an Stelle des oben angeführten Kondensationsproduktes die äquivalente Menge desjenigen aus 5-M-toluylamino-z, i-aminothiophenol und Chloranil, so erhält man einen Farbstoff, der Baumwolle in lebhaft grünstichigblauen Tönen von gleich guten Echtheitseigenschaften im Schwefelnatriumbade oder in der Küpe anfärbt.The process can be carried out in the same way with other quinone vat dyes of the above type and with other conventional sulphurizing agents. Used one z. B. instead of the condensation product listed above, the equivalent Amount of that from 5-M-toluylamino-z, i-aminothiophenol and chloranil, so obtained one dye, the cotton in lively greenish blue tones of the same good fastness properties in a sulfur-sodium bath or in the vat.
