Patentiert im Deutschen Reiche vom 27. August 1909 ab.Patented in the German Empire on August 27, 1909.
In der Patentschrift 162156 ist die Darstellung grüner Schwefelfarbstoffe aus den Indophenolen aus Arylnaphtylaminsulfosäuren und ρ - Aminophenol beschrieben. Die nach diesem Verfahren erhaltenen Farbstoffe liefern Färbungen von sehr mangelhafter Kochechtheit. In the patent specification 162156 the illustration is green sulfur dyes from the indophenols from arylnaphtylamine sulfonic acids and ρ - aminophenol. The dyes obtained by this process provide Dyeings of very poor cooking fastness.
Ferner ist in dem britischen Patent 11003/03 ein Verfahren zur Darstellung grüner Schwefelfarbstoffe aus den durch Oxydation von a-Naphtylamin oder dessen Sulfosäuren einerseits und ρ-Aminophenol andererseits erhältlichen Indophenolen unter Zusatz von Kupfersalzen erwähnt. Die Farbstoffe dieses Verfahrens liefern jedoch nur sehr blaustichige, stumpfe grüne Nuancen.In addition, British patent 11003/03 mentions a process for the preparation of green sulfur dyes from the indophenols obtainable by oxidation of a- naphthylamine or its sulfonic acids on the one hand and ρ-aminophenol on the other hand, with the addition of copper salts. However, the dyes in this process only produce dull green nuances with a very bluish cast.
Es wurde nun gefunden, daß durch Verschmelzen von Indophenolen aus ρ-Aminophenol oder dessen Derivaten, wie z. B. Chlor-Substitutionsprodukten einerseits und Aryl-cinaphtylaminen andererseits mit Alkalipolysulfiden Farbstoffe erhalten werden, welche Baumwolle direkt in klaren gelb- bis blaustichig grünen Nuancen von hervorragenden Echtheitseigenschaften, insbesondere sehr großer Kochechtheit, anfärben.It has now been found that by fusing indophenols from ρ-aminophenol or its derivatives, such as. B. Chlorine Substitution Products on the one hand and aryl-cinaphthylamines on the other hand with alkali polysulphides Dyes are obtained, which cotton directly in clear yellow to blue cast green shades of excellent fastness properties, especially very large ones Fastness to cook, staining.
32,6 Teile i-Phenylamino-4-p-oxyphenylnaphtylamin werden in eine wässerige oder alkoholische Lösung von 25 Teilen Schwefel, 85 Teilen kristallisiertem Schwefelnatrium und 7 Teilen Kupfersulfat eingetragen und bis zum Verschwinden des Ausgangskörpers erhitzt. Die fertige Schmelze kann entweder getrocknet und direkt zum Färben verwendet oder noch weiteren Reinigungsprozessen unterworfen werden. Der so erhaltene Farbstoff färbt Baumwolle in schönen grünen Tönen an.32.6 parts of i-phenylamino-4-p-oxyphenylnaphthylamine are in an aqueous or alcoholic solution of 25 parts of sulfur, 85 parts crystallized sodium sulphide and 7 parts of copper sulfate registered and up to Disappearance of the original body heated. The finished melt can either be dried and used directly for dyeing or subjected to further cleaning processes. The dye thus obtained stains cotton in beautiful green tones.
Ähnliche Resultate erhält man, wenn man an Stelle des oben genannten Leukindophenols die Leukindophenole aus anderen Aryl-a-naphtylaminen und den Substitutionsprodukten des ρ - Aminophenols, wie 1 - Tolylamino - 4 oxyphenylnaphtylamin, i-Phenylamino-p-oxym · m-dichlorphenylnaphtylamin oder die Indophenole selbst verwendet.Similar results are obtained if one uses instead of the above-mentioned leukindophenol the leukindophenols from other aryl-a-naphthylamines and the substitution products of ρ - aminophenol, such as 1 - tolylamino - 4 oxyphenylnaphtylamine, i-phenylamino-p-oxymm-dichlorophenylnaphthylamine or the indophenols used itself.
