Description
Zusatzpatent zum hauptpatent Nr. 141535. Verfahren zur Herstellung eines metallhaltigen Farbstoffes. Es wurde gefunden, dass man. einen neuen metallhaltigen Farbstoff erhält, wenn man den Farbstoff aus diazotiertem 4-Chlor-2- amino-l-plieno1 und Resorcin mit einem eisen- und nickelhaltigen Produkt, das durch Einwirkung einer hydrogylgruppenhaltigen organischen Verbindung auf Eisen- und Nik- kelverbindungen in Gegenwart von Alkalien erhalten wird, behandelt.
Der neue Farbstoff löst sich schwer mit brauner Farbe in Wasser, leicht braunrot in Natronlauge und braungelb in konzen trierter Schwefelsäure. Aus der rotstickig braun gefärbten Lösung in Zaponlack erhält man braunstickig orange gefärbte, lichtechte Überzüge auf geeigneten Unterlagen.
<I>Beispiel:</I> 5,29 Gewichtsteile des Farbstoffes aus diazotiertem 4-Chlor-2-amino-l-phenol und Resorcin werden in 400 Teilen Wasser und 10 Teilen Natronlauge von 36 B6 gelöst und mit einer aus 0,97 Teilen Eisenchlorid und 3,92 Teilen kristallisiertem Nickelsulfat, 7 Teilen Glyzerin und 20 Teilen Natron lauge hergestellten alkalischen eisen- und nickelhaltigen Lösung 1 Stunde am Rückfluss gekocht. Hierauf wird erkalten gelassen, neutralisiert, filtriert und getrocknet.
Ein gleiches Produkt wird erhalten, wenn statt Glyzerin andere liydroxylgruppenhal- tige organische Verbindungen, wie Glykol. Tannin, Gallussäure, Zuckerarten, Kohlen hydrate, verwendet werden.
Additional patent to the main patent No. 141535. Process for the production of a metal-containing dye. It was found that one. A new metal-containing dye is obtained when the dye is made from diazotized 4-chloro-2-amino-l-plieno1 and resorcinol with an iron and nickel-containing product that is produced by the action of an organic compound containing hydrogyl groups on iron and nickel compounds in the presence of Alkalis is obtained, treated.
The new dye is difficult to dissolve in water with a brown color, slightly brown-red in sodium hydroxide solution and brown-yellow in concentrated sulfuric acid. The solution in zapon varnish, which is colored red and brown, gives brown, orange colored, lightfast coatings on suitable substrates.
<I> Example: </I> 5.29 parts by weight of the dye from diazotized 4-chloro-2-amino-1-phenol and resorcinol are dissolved in 400 parts of water and 10 parts of sodium hydroxide solution of 36 B6 and one of 0.97 Parts of iron chloride and 3.92 parts of crystallized nickel sulfate, 7 parts of glycerol and 20 parts of sodium hydroxide solution prepared alkaline iron and nickel-containing solution refluxed for 1 hour. It is then left to cool, neutralized, filtered and dried.
The same product is obtained if, instead of glycerine, other organic compounds containing hydroxyl groups, such as glycol. Tannin, gallic acid, sugars, carbohydrates can be used.
