EMI1.1
Es wurde gefunden, dass, wenn man die durch gemeinsame Oxydation von Mono-oder Dialkyl-#035-naphtylaminen einerseits und p-Aminophenol oder dessen Derivaten und Snbstitutionsprodukten andererseits erhältlichen Indophenole bzw. die daraus durch Reduktion entstehenden Leukoindophenole mit Alkalipolysulfid in Gegenwart von Kupfer oder Kupferverbindungen erhitzt, zu wertvollen grünen Schwefelfarbstoffen gelangt, die sich durch grosse Kochechtheit auszeichnen.
EMI1.2
105 bis zum Verschwinden des Ausgangskörpers erhitzt. Die fertige Schmelze kann direkt getrocknet und noch weiteren Reinigungsprozessen unterworfen werden. Der so erhaltene Farbstoff färbt Baumwolle in klaren grünen Tönen an.
Die angeführten Mengenverhältnisse von Schwefelnatrium und Schwefel sowie Temperatur und Dauer der Reaktion können selbstredend innerhalb weiter Grenzen abgeändert werden.
Zu ähnlichen Farbstoffen gelangt man, wenn man andere der genannten Indophenole bzw. ihre Loukoverbindungnn verwendet, wie Indophenole aus Mono-oder Dimethyl- -#035-naphtylamin, Diäthyl-#035-naphtylamin, p-Aminophenol, p-aminokresol.

EMI1.1
It has been found that if the indophenols or the leucoindophenols formed therefrom by reduction with alkali polysulphide in the presence of copper or, on the other hand, the indophenols obtained by joint oxidation of mono- or dialkyl- # 035-naphthylamines on the one hand and p-aminophenol or its derivatives and substitution products Heated copper compounds, leads to valuable green sulfur pigments, which are characterized by great cooking fastness.
EMI1.2
105 heated until the initial body disappears. The finished melt can be dried directly and subjected to further cleaning processes. The dye thus obtained stains cotton in clear green tones.
The specified proportions of sodium sulphide and sulfur as well as the temperature and duration of the reaction can of course be changed within wide limits.
Similar dyes are obtained if other of the indophenols mentioned or their louko compounds are used, such as indophenols from mono- or dimethyl- - # 035-naphthylamine, diethyl- # 035-naphthylamine, p-aminophenol, p-aminocresol.
