Description
Zusatzpatent zum Hauptpatent Nr. 159942. Verfahren zur Herstellung eines neuen ehromhaltigen Farbstoffes. Es wurde gefunden, dass man einen neuen chromhaltigen Farbstoff erhält, wenn man den Azofarbstoff aus diazotierter 1-Amino-2-oxy- naphthalin-4,6-disulfonsäure und 1-Phenyl-3- methyl-5-pyrazolon mit chromabgebenden Mit teln behandelt.
Der erhaltene chromhaltige Farbstoff stellt ein dunkelrotes Pulver dar, das sich in kon zentrierter Schwefelsäure mit orangegelber, in Wasser mit blaustichig-roter Farbe löst und Wolle aus saurem Bade in echten Rosa tönen färbt.
<I>Beispiel:</I> 54,8 Teile des Farbstoffes aus diazotierter 1-Amino-2-oxynaphthalin-4,6-disulfosäure und 1-Phenyl-3-methyl-5-pyrazolon (Mononatrium salz) werden in 1000 Teilen Wasser gelöst und nach Zugabe einer 5 /oigen Fluorchrom- lösung, entsprechend 7,6 Teilen Ors0s, etwa 3 Stunden rückfliessend gekocht, durch Zugabe von Kochsalz wird die Chromverbindung ab geschieden.
Additional patent to main patent No. 159942. Process for the production of a new Ehrom-containing dye. It has been found that a new chromium-containing dye is obtained if the azo dye from diazotized 1-amino-2-oxynaphthalene-4,6-disulfonic acid and 1-phenyl-3-methyl-5-pyrazolone is treated with chromium-releasing agents .
The chromium-containing dye obtained is a dark red powder which dissolves in concentrated sulfuric acid with an orange-yellow color, in water with a bluish-red color and dyes wool from an acid bath in real pink tones.
<I> Example: </I> 54.8 parts of the dye from diazotized 1-amino-2-oxynaphthalene-4,6-disulfonic acid and 1-phenyl-3-methyl-5-pyrazolone (monosodium salt) are used in 1000 parts Dissolved water and, after adding a 5% fluorochromium solution, corresponding to 7.6 parts of OrsOs, refluxed for about 3 hours, the chromium compound is separated off by adding sodium chloride.
