Verfahren zur Darstellung gelber Schwefelfarbstoffe.
Es wurde gefunden, dass man beim Verschmelzen von 3-Nitro-oder 3-Amino-4-azetyltoluidin mit zwei oder mehr Molekülen Benzidin und Schwefel zu gelben Schwefelfarbstoffen gelangt, die sich durch klare griinstiehige Nuance und sehr gute Kocheehtheit auszeichnen.
Beispiel : 8.5 Gewichtsteile 3-Amino-4-azettoluid, 47.5 Gewichtsteile Benzidin und 112 Gewichtsteile Schwefel werden mehrere Stunden von 180 bis 26 (T C erhitzt. Die gemahlene Schmelze wird mit Sehwefelnatrium gelöst, der Farbstoff mit Säuren ausgefällt, filtriert und getrocknet. Der so als gelbes Pulver erhaltene Farbstoff färbt Baumwolle aus sehwefelnatriumhaltigem Bade in gelbbraunen Tönen an, die beim Trocknen, Dämpfen oder Absäuel'l1 in ein klare grünstichiges Gelb übergehen. Nimmt man in diesem Beispiel die äquivalente Menge 3-Nitro-4-azettoluid. so erhält man einen ähnlichen Farbstoff.

Process for the preparation of yellow sulfur dyes.
It has been found that when 3-nitro- or 3-amino-4-acetyltoluidine is fused with two or more molecules of benzidine and sulfur, yellow sulfur dyes are obtained, which are distinguished by a clear greenish shade and very good boiliness.
Example: 8.5 parts by weight of 3-amino-4-azettoluide, 47.5 parts by weight of benzidine and 112 parts by weight of sulfur are heated for several hours from 180 to 26 (TC). The ground melt is dissolved with sodium sulfate, the dye is precipitated with acids, filtered and dried The dye obtained as a yellow powder stains cotton from a bath containing sodium sulphide in yellow-brown shades, which turn into a clear greenish yellow when dried, steamed or peeled off. In this example, if the equivalent amount of 3-nitro-4-azettoluide is obtained a similar dye.
