Description
Zusatzpatent zum Hauptpatent Nr. 143026. Verfahren zur Herstellung eines neuen metallhaltigen Farbstoffes. Es wurde gefunden; dass man einen neuen metallhaltigen Farbstoff erhält, wenn man den Azofarbstoff aus 5-Nitro-2-diazo-l-pbenol und 1-Amino-8-oxynaphthalin-4-srilfosäure mit chrom- und kupferabgebenden Mitteln be handelt.
Der erhaltene metallhaltige Farbstoff bil det getrocknet ein dunkles Pulver, das sich in Wasser mit blaugrüner Farbe löst und Naturseide in blaugrünen Tönen färbt.
<I>Beispiel:</I> 8,08 Teile des Farbstoffes aus diazotier- tem 5-Nitro-2-amino-l-plienol und 1-Amino- 8-oxynaphthalin-4-sulfosäure werden in 500 Teilen Wasser gelöst und mit einer 1,06 Tei len Crz Os entsprechenden Menge Fluorchrom am Rückfluss gekocht. Nach 24 Stunden werden 3,25 Teile kristallisiertes Kupfersul fat zugegeben, die frei werdende Mineralsäure mit 1,77 Teilen Natriumacetat abgestumpft und noch kurze Zeit weitergekocht.
Hierauf wird die gebildete Chrom-Kupferverbindung des Farbstoffes mit Kochsalz abgeschieden, filtriert und bei mässigerTemperaturgetrocknet.
Additional patent to main patent no. 143026. Process for the production of a new metal-containing dye. It was found; that you get a new metal-containing dye if you treat the azo dye from 5-nitro-2-diazo-1-pbenol and 1-amino-8-oxynaphthalene-4-srilfosäure with chromium and copper donating agents be.
When dried, the metal-containing dye obtained forms a dark powder which dissolves in water with a blue-green color and dyes natural silk in blue-green tones.
<I> Example: </I> 8.08 parts of the dye from diazotized 5-nitro-2-amino-1-plienol and 1-amino-8-oxynaphthalene-4-sulfonic acid are dissolved in 500 parts of water and mixed with an amount of fluorochrome corresponding to 1.06 parts of Crz Os is refluxed. After 24 hours, 3.25 parts of crystallized copper sulfate are added, the mineral acid released is blunted with 1.77 parts of sodium acetate and the mixture is boiled for a short time.
The chromium-copper compound formed in the dye is then deposited with common salt, filtered and dried at a moderate temperature.
