Zusatz zum Patente 241615 vom 16. Juni 1910.Addendum to patent 241615 from June 16, 1910.
Patentiert im Deutschen Reiche vom 28. August 1910 ab. Längste Dauer: 15. Juni 1925.Patented in the German Empire on August 28, 1910. Longest duration: June 15, 1925.
Durch das Patent 241615 ist ein Verfahren
geschützt zur Darstellung beizenfärbender Oxazinfarbstoffe aus Pyrogallolderivaten und
p-Nitrosophenolen oder Chinonchlorimiden.
Es wurde nun gefunden, daß man zu diesen Farbstoffen auch dadurch gelangen kann,
daß man Pyrogallolderivate mit p-Aminophenolen, ihren Derivaten, Analogen und Homologen
zusammen oxydiert oder aber auf p-Oxyazoverbindungen einwirken läßt.A process for the preparation of stain-coloring oxazine dyes from pyrogallol derivatives and p-nitrosophenols or quinone chlorimides is protected by patent 241615.
It has now been found that these dyes can also be obtained by oxidizing pyrogallol derivatives together with p-aminophenols, their derivatives, analogs and homologues, or by allowing p-oxyazo compounds to act.
Von dem Resorufin unterscheiden sich diese Farbstoffe typisch durch das Vorhandensein einer ■ weiteren Hydroxylgruppe —■ in o-Stellung zum Bindesauerstoff —, wodurch sie zu Beizenfarbstoffen werden.These dyes typically differ from resorufin in their presence a ■ further hydroxyl group - ■ in the o-position to binding oxygen - whereby they become mordant dyes.
Von den nach Patent 15915 erhältlichen Farbstoffen, als deren Charakteristikum ihre »schwach basische (nicht saure) Natur« in dem Patent betont wird, unterscheiden sich die neuen Produkte durch ihren ausgesprochen sauren Charakter. Während die Farbstoffe des Patents 15915 als Indophenole anzusprechen sind, handelt es sich hier um Oxazine.Of those available under patent 15915 Dyes, the characteristic of which is their "weakly basic (not acidic) nature" in the Patent is emphasized, the new products differ by their pronounced acidic character. While the dyes of the patent 15915 are to be addressed as indophenols are, these are oxazines.
5,5 Teile p-Aminophenol und 8,5 Teile GaIlaminsäure werden in 150 Teilen Schwefelsäure von 6o° Be. gelöst und 10 Teile Braunstein, 90 prozentig, unter Kühlung allmählich zugegeben. Nach beendigter Oxydation wird auf Eiswasser gegossen und abgesaugt. Man kann das Produkt durch Lösen in Alkali, Filtrieren und Ausfällen mit Säuren reinigen. Es ist ein dunkles Pulver, das sich in verdünnter Natronlauge mit violetter Farbe löst. Der Farbstoff liefert einen violetten Chromlack.5.5 parts of p-aminophenol and 8.5 parts of gallic acid are in 150 parts of sulfuric acid of 60 ° Be. dissolved and 10 parts of brownstone, 90 percent, gradually added with cooling. When the oxidation is complete, it will open Poured ice water and sucked off. One can filter the product by dissolving it in alkali and clean precipitates with acids. It is a dark powder that can be diluted in Sodium hydroxide solution dissolves with a violet color. The dye provides a purple chrome varnish.
