Description
Zusatzpatent zum Hauptpatent Nr. 189649. Verfahren zur Herstellung eines sauren Wollfarbstoffes. Gegenstand vorliegenden Patentes ist ein Verfahren zur Herstellung eines sauren Wollfarbstoffes, das dadurch gekennzeichnet ist, dass man den Farbstoff der Formel:
EMI0001.0004
mit einem sulfonierenden Mittel behandelt. Der neue Farbstoff, der zwei Sulfogrup- pen im Molekül enthält, löst sich in konzen trierter Schwefelsäure mit grüner, in Wasser mit blauer Farbe und färbt Wolle in blauen Tönen von guten Echtheitseigenschaften.
Beispiel: Der Farbstoff der Formel
EMI0001.0009
wird zwecks Sulfonierung in der fünffachen Menge 32 % igen Oleums mehrere Stunden er hitzt, bis eine Probe in verdünnter Natrium acetatlösung klar löslich ist. Die Aufarbei tung erfolgt in üblicher Weise durch Aus giessen auf Eis, Filtrieren und Überführung in das Natronsalz. Der erhaltene Farbstoff enthält zwei Sulfogruppen im Molekül.
Er löst sich in konzentrierter Schwefelsäure mit grüner, in Wasser mit blauer Farbe und färbt Wolle in blauen Tönen von guten Echtheits eigenschaften.
Additional patent to main patent No. 189649. Process for the production of an acidic wool dye. The present patent relates to a process for the preparation of an acidic wool dye, which is characterized in that the dye of the formula:
EMI0001.0004
treated with a sulfonating agent. The new dye, which contains two sulfo groups in the molecule, dissolves in concentrated sulfuric acid with a green color and in water with a blue color and dyes wool in blue shades with good fastness properties.
Example: The dye of the formula
EMI0001.0009
is for the purpose of sulfonation in five times the amount of 32% oleum for several hours he heated until a sample in dilute sodium acetate solution is clearly soluble. The processing is carried out in the customary manner by pouring out onto ice, filtering and converting into the sodium salt. The dye obtained contains two sulfo groups in the molecule.
It dissolves in concentrated sulfuric acid with green color, in water with blue color and dyes wool in blue shades with good fastness properties.
