Description
Verfahren zur Darstellung eines blauen Schwefelfarbstoffes. Es wurde gefunden, dass das aus Benzyl- tnethyla.nilin und Nitrosophenol, Chinonchlori- mid oder p-Aminophenol oder aus p-Amino- benzylmethylanilin und Phenol erhältliche Indophenol in der Alkali-Polysulfidschmelze einen kochechten, blauen Schwefelfarbfstoff von klaren Nuancen und aussergewöhnlicher Chlorechtheit liefert.
An Stelle des Indo- phenols selbst kann auch dessen Leukov er- bindung verwendet werden.
Beispiel: Das aus 28,6 Gewichtsteilen -L#lethyl- benzylanilin und Chinonchlorimid erhaltene Indophenol wird in alkoholischer Lösung mit einem Polysulfid aus 80 Gewichtsteilen tech nischen calciniertem Schwefelnatrium und 100 Gewichtsteilen Schwefel 60 Stunden am Rückflusskühler gekocht und nach den übli chen Methoden aufgearbeitet. Der Farbstoff färbt Baumwolle aus der Hydrosulfitküpe in klaren, grünstichig blauen Tönen von sehr guter Koch-, Chlor- und Lichtechtheit.
Process for the preparation of a blue sulfur dye. It has been found that the indophenol obtainable from benzyl methylaniline and nitrosophenol, quinone chloride or p-aminophenol or from p-aminobenzylmethylaniline and phenol in the alkali polysulfide melt provides a boiling, blue sulfur color of clear nuances and exceptional chlorinefastness .
Instead of the indophenol itself, its Leukov compound can also be used.
Example: The indophenol obtained from 28.6 parts by weight of -L # lethyl- benzylaniline and quinone chlorimide is boiled in an alcoholic solution with a polysulfide of 80 parts by weight of technical calcined sodium sulfur and 100 parts by weight of sulfur for 60 hours on a reflux condenser and worked up according to the usual methods. The dye dyes cotton from the hydrosulfite vat in clear, greenish blue shades of very good boil, chlorine and lightfastness.
