Description
Verfahren zur Herstellung eines metallhaltigen Farbstoffes. Es wurde gefunden, dass man einen neuen metallhaltigen Farbstoff erhält, wenn man den Farbstoff aus dianotiertem 4-Chlor-2-. amino-l-phenol und Resorcin mit einem eisen haltigen Produkt, das durch Einwirkung einer hydroxylgruppenhaltigen organischen Ver bindung auf ein Eisensalz in Gegenwart von Alkalien erhalten wird, behandelt.
Der entstandene Farbstoff stellt ein schwarzbraunes Pulver dar, ist in Wasser schwer, in Natronlauge mit olivebrauner Farbe, in konzentrierter Schwefelsäure mit gelbbrauner Farbe löslich. Aus einer. Lösung in Zaponlack erhält man auf Aluminiumfolie braune -Überzüge von guter Lichtechtheit.
<I>Beispiel:</I> 5,27 Teile des Farbstoffes aus 4-Chlor-2- amino-l-phenol und Resorcin werden in 400 Teilen Wasser und 10 Teilen Natronlauge von 36 Be gelöst und kochend mit einer Lösung von 3,5 Teilen Eisenchlorid in 50 Teilen Wasser, 20 Teilen Natronlauge von 36 B6 und 7 Teilen Glyzerin versetzt, 3 Stunden am Rückflug gekocht, nach dem Erkalten essigsauer abgeschieden, neutral gewaschen und bei 50-60 getrocknet.
Ein gleiches Endprodukt wird erhalten, wenn statt Glyzerin andere hydroxylgruppen- haltige organische Verbindungen, wie Glykol, Tannin, Gallussäure, Zuckerarten, Kohlen hydrate, verwendet werden.
Process for the production of a metal-containing dye. It has been found that a new metal-containing dye is obtained if the dye is obtained from dianotized 4-chloro-2-. amino-l-phenol and resorcinol with an iron-containing product which is obtained by the action of an organic compound containing hydroxyl groups on an iron salt in the presence of alkalis, treated.
The resulting dye is a black-brown powder, is difficult to dissolve in water, in sodium hydroxide solution with an olive-brown color, in concentrated sulfuric acid with a yellow-brown color. From a. Solution in zapon varnish gives brown coatings of good lightfastness on aluminum foil.
<I> Example: </I> 5.27 parts of the dye from 4-chloro-2-amino-1-phenol and resorcinol are dissolved in 400 parts of water and 10 parts of 36 Be sodium hydroxide solution and boiled with a solution of 3, 5 parts of iron chloride in 50 parts of water, 20 parts of sodium hydroxide solution of 36 B6 and 7 parts of glycerol are added, the mixture is boiled for 3 hours on the return flight, after cooling it is separated in acetic acid, washed neutral and dried at 50-60.
The same end product is obtained if other organic compounds containing hydroxyl groups, such as glycol, tannin, gallic acid, sugars, carbohydrates, are used instead of glycerine.
