Description
Verfahren zur Herstellung eines chromhaltigen Farbstoffes. Nach dem Hauptpatent erhält man einen neuen chromhaltigen Farbstoff, wenn man 4-Nitro-2-aminophenol-6-sulfonsäure mit Salicylaldehyd umsetzt und die entstehende Azomethinverbindung mit einem chromab gebenden Mittel behandelt.
Es wurde nun gefunden, dass man eben falls einen neuen chromhaltigen Farbstoff erhält, wenn man 4-Nitro-2-aminophenol-6- sulfonsäure mit 2-Oxy-l-naphthaldehyd um setzt und die entstehende Azomethinverbin- dung mit einem chromabgebenden Mittel be handelt.
Man kann auch hier sowohl bei gewöhn lichem, als auch bei erhöhtem Druck arbeiten. Der neue Farbstoff kann zum Färben von Wolle, Seide, Leder, Baumwolle oder Kunst seide verwendet werden. Er ist auch zum Färben in saurem Bade geeignet. Beispiel: Man kocht 23,4 Teile 4-Nitro-2-amino- phenol-6-sulfonsäure, 28 Teile kristallisiertes Natriumacetat und 17,2 Teile 2-Ogy-1- naphthaIdehyd mit 800 Teilen Wasser und gibt eine Chromformiatlösung zu, die 9 Tei len Chromoxyd entspricht.
Nach mehrstündi gem Kochen kristallisiert der chromhaltige Farbstoff aus. Nach .dem Erkalten der Lösung saugt man ihn ab und trocknet ihn. Er färbt Wolle in braunstichig orange Tönen.
Process for the production of a chromium-containing dye. According to the main patent, a new chromium-containing dye is obtained if 4-nitro-2-aminophenol-6-sulfonic acid is reacted with salicylaldehyde and the resulting azomethine compound is treated with a chromabending agent.
It has now been found that a new chromium-containing dye is also obtained if 4-nitro-2-aminophenol-6-sulfonic acid is reacted with 2-oxy-1-naphthaldehyde and the azomethine compound formed is treated with a chromium-releasing agent .
Here, too, you can work with both normal and increased pressure. The new dye can be used to dye wool, silk, leather, cotton or artificial silk. It is also suitable for dyeing in an acid bath. Example: 23.4 parts of 4-nitro-2-aminophenol-6-sulfonic acid, 28 parts of crystallized sodium acetate and 17.2 parts of 2-Ogy-1-naphthaldehyde are boiled with 800 parts of water and a chromium formate solution is added which Part of chromium oxide corresponds.
After several hours of boiling, the chromium-containing dye crystallizes out. After the solution has cooled down, it is suctioned off and dried. It dyes wool in brownish orange tones.
