Description
Zusatzpatent zum Hauptpatent Nr. 178542. Es wurde gefunden, dass man einen kom plex gebundenes Metall enthaltenden Farb stoff herstellen kann, wenn man 1 Mol @dia.zo- tiertes 4-Nitro-2-amino-l-phenol, 1 Mol diazo- tierte 4-Nitro-2-amino-l-phenol-6-sulfonsäure, 1 Mol 1.3-Dioxybenzol und ein Mangan, sowie ein Eisen abgebendes Mittel aufein ander einwirken lässt.
Der erhaltene Farbstoff stellt ein in Wasser mit gelbbrauner Farbe leicht lös liches, braunschwarzes Pulver dar, das sich in konzentrierter Schwefelsäure mit rot- oranger Farbe löst. Er färbt aus, ameisen saurem Bade vegetabilisch gegerbtes Leder oder aus neutralem Bade Chromleder in oliv- stichigen dunkelbraunen, lichtechten Tönen.
Das Verfahren kann beispielsweise derart ausgeführt werden, dass man auf das Ein wirkungsprodukt aus 1 Mol diazotiertem 4-Nitro-2-amino-l-phenol und 1 Mol 1.3- Dioxybenzol ein Mangan abgebendes Mittel, dann 1. Mol diazotierte 4-Nitro-2-amino-l- phenol-6-sulfonsäure und hierauf ein Eisen abgebendes Mittel einwirken lässt.
<I>Beispiel:</I> 34 Teile der Manganverbindung des Farb stoffes aus diazotiertem 4-Nitro-2-amino-l- phenol und 1. 3-Dioxybenzol werden in 300 Teilen Wasser, sowie 27 Teilen 30%iger Natronlauge in der Kälte gelöst, dann mit der neutralisierten Diazoverbindung aus 23,4 Teilen 4-Nitro-2-amino-l-phenol-6-sulfon- säure versetzt und bei 10 bis <B>1,5'</B> während 10 bis 12 Stunden gerührt. Nach dieser Zeit ist die Kupplung beendet.
Nun erwärmt man auf<B>60',</B> versetzt mit 11,5 Teilen 30 % iger . Salzsäure und 16,2 Teilen Ferrichlorid in Form einer 20 % igen wässerigen Lösung. Man erwärmt zum Kochen und hält während drei Stunden unter Rühren am Rückfluss- kühler auf 102 bis 104'. Hierauf versetzt man mit 100 Teilen Kochsalz, lässt abkühlen, filtriert und trocknet bei mässiger Tempe ratur.
Additional patent to the main patent no. 178542. It has been found that a complex metal-containing dye can be produced if you 1 mol @ dia.zo- tosed 4-nitro-2-amino-1-phenol, 1 mol diazo oriented 4-nitro-2-amino-1-phenol-6-sulfonic acid, 1 mole of 1,3-dioxybenzene and a manganese, and an iron-releasing agent on one another can act.
The dye obtained is a brown-black powder which is easily soluble in water with a yellow-brown color and which dissolves in concentrated sulfuric acid with a red-orange color. It dyes vegetable tanned leather from ants acid bath or from neutral bath chrome leather in olive-tinged dark brown, lightfast tones.
The process can, for example, be carried out in such a way that a manganese-releasing agent, then 1st mole of diazotized 4-nitro-2, is applied to the product of 1 mol of diazotized 4-nitro-2-amino-1-phenol and 1 mol of 1,3-dioxybenzene -amino-1-phenol-6-sulfonic acid and then an iron releasing agent can act.
<I> Example: </I> 34 parts of the manganese compound of the dye from diazotized 4-nitro-2-amino-1-phenol and 1,3-dioxybenzene are dissolved in 300 parts of water and 27 parts of 30% sodium hydroxide solution Cold dissolved, then mixed with the neutralized diazo compound from 23.4 parts of 4-nitro-2-amino-1-phenol-6-sulfonic acid and at 10 to 1.5 'for 10 to 12 Stirred for hours. After this time, the coupling is ended.
Now it is heated to <B> 60 ', </B> mixed with 11.5 parts of 30% strength. Hydrochloric acid and 16.2 parts of ferric chloride in the form of a 20% strength aqueous solution. The mixture is heated to the boil and kept at 102 to 104 ° for three hours with stirring on the reflux condenser. 100 parts of sodium chloride are then added, the mixture is allowed to cool, filtered and dried at a moderate temperature.
