Description
<B>Zusatzpatent</B> zum Hauptpatent Nr. 189649. Verfahren zur Herstellung eines sauren Wollfarbstoffes. Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung eines sauren Wollfarbstoffes, das dadurch gekennzeichnet ist, dass man den Farbstoff der Formel:
EMI0001.0002
mit einem sulfonierenden Mittel behandelt. Der neue Farbstoff, der zwei Sulfogrup- pen im Molekül enthält, löst sich in konzen trierter Schwefelsäure grün, in Wasser blau und färbt Wolle in blauen Tönen von guten Echtheitseigenschaften.
<I>Beispiel:</I> Das basische Safranin der Formel:
EMI0001.0007
das erhältlich ist, indem man das aus m-To- lyl-ss-naphthylamin und Nitrosodiäthylanilin in üblicher Weise erhaltene Isorosindulin in bekannter Weise mit Bisulfit in die 6-Mono- sulfonsäure überführt und letztere in alkoho lischer Lösung mit Xylylendiamin umsetzt.
wird durch mehrstündiges Erwärmen mit 5 Teilen 62 % igen Oleums sulfoniert, bis eine Probe in verdünnter Natriumacetatlösung klar löslich ist. Die Aufarbeitung geschieht in üblicher Weise durch Ausgiessen auf Eis, Filtrieren und Überführung in das Natron salz.
Der neue Farbstoff enthält zwei Sulfo- gruppen im Molekül. Er löst sich in konzen trierter Schwefelsäure grün, in Wasser blau und färbt Wolle in blauen Tönen von guten Echtheitseigenschaften.
<B> Additional patent </B> 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:
EMI0001.0002
treated with a sulfonating agent. The new dye, which contains two sulfo groups in the molecule, dissolves green in concentrated sulfuric acid, blue in water and dyes wool in blue shades with good fastness properties.
<I> Example: </I> The basic safranin of the formula:
EMI0001.0007
this can be obtained by converting the isorosindulin obtained in the usual way from m-tolyl-ss-naphthylamine and nitrosodiethylaniline in a known manner with bisulfite into the 6-monosulfonic acid and reacting the latter in an alcoholic solution with xylylenediamine.
is sulfonated by heating for several hours with 5 parts of 62% oleum until a sample is clearly soluble in dilute sodium acetate solution. Working up is done in the usual way by pouring onto ice, filtering and converting into the sodium salt.
The new dye contains two sulfo groups in the molecule. It dissolves green in concentrated sulfuric acid, blue in water and dyes wool in blue shades with good fastness properties.
