Description
<B>Zusatzpatent</B> zum Hauptpatent Nr. 240992. Verfahren zur Herstellung eines ehromierten Farbstoffes. Gegenstand vorliegenden Patentes ist ein Verfahren zur Herstellung eines chromierten Farbstoffes.
Das Verfahren ist dadurch ge kennzeichnet, dass der Farbstoff aus diazo- tierter 2-Amino-benzol-l-carbonsäure und 1-Naphthol - 8 -sulfonsäure- 3 -sulf onsäure-N- äthyl-N-phenyl-amid mit chromsalicylsaurem Ammonium behandelt wird.
Der entstandene neue chromhaltige Kom- plexf arbstof f ist ein dunkelweinrotes, in Wasser gut lösliches Pulver. Er färbt Wolle aus ameisensaurem Bad in reinen, weinroten Tönen von guter Gleichmässigkeit. Die Färbungen zeichnen sich durch gute Walk-, Schweiss-, Reib- und sehr gute Licht echtheit aus.
Beispiel: 59,9 Teile Dinatriumsalz des Farbstoffes 2-Amino-benzol-l-carbonsäure -> 1-Naph- thol - 8 -sulf onsäure-3-oulfonsäure-N-äthyl-N- phenyl-amid werden in 1000 Teilen Wasser verrührt und nach Zugabe von 240 Teilen einer Lösung von chromsalicylsaurem Ammo- nium entsprechend 9,
1 Teilen Chromoxyd so lange unter Rückfluss beim Siedepunkt ge- rührt, bis der Farbstoff in komplexe Form übergegangen ist, was nach 15-20 Stunden der Fall ist. Die tiefrote Lösung wird heiss von etwas unlöslichem chromhaltigem Neben produkt filtriert und der Chromkomplegfarb- stoff durch Sättigen mit Kochsalz isoliert.
<B> Additional patent </B> to main patent no. 240992. Process for the production of an honored dye. The present patent relates to a process for the preparation of a chromium-plated dye.
The process is characterized in that the dye is treated with diazo-tated 2-amino-benzene-1-carboxylic acid and 1-naphthol-8-sulfonic acid-3-sulfonic acid-N-ethyl-N-phenyl-amide with chromsalicylic acid ammonium becomes.
The resulting new chromium-containing complex dye is a dark wine-red powder that is readily soluble in water. He dyes wool from an acidic bath in pure, wine-red tones of good evenness. The dyeings are characterized by good flexing, perspiration, rubbing and very good lightfastness.
Example: 59.9 parts of the disodium salt of the dye 2-amino-benzene-1-carboxylic acid -> 1-naphthol - 8-sulfonic acid-3-sulfonic acid-N-ethyl-N-phenyl-amide are stirred in 1000 parts of water and after adding 240 parts of a solution of chromsalicylic acid ammonium corresponding to 9,
1 part chromium oxide stirred under reflux at the boiling point until the dye has changed into a complex form, which is the case after 15-20 hours. The deep red solution is filtered while hot from some insoluble chromium-containing by-product and the chromium complex dye is isolated by saturating it with sodium chloride.
