KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Es hat sich gezeigt, daß man rote beizenfärbende Wollfarbstoffe erhält, wenn man die durch Sulfurieren von o-Aminoazoanisol entstehende Monosulfosäure mit Salicylsäure oder deren Homologen kombiniert.It has been found that red stain-dyeing wool dyes are obtained if the monosulfonic acid formed by sulfurizing o-aminoazoanisole with salicylic acid or their homologues combined.
33,8 Gewichtsteile o-Arninoazoanisolmonosulfosäure, erhalten durch Sulfonation von33.8 parts by weight of o-aminoazoanisole monosulfonic acid, obtained by sulfonation of
ίο o-Aminoazoanisol mit schwach rauchender Säure in der Kälte, werden in üblicher Weise mit einer Lösung von 7 Gewichtsteilen Natriumnitrit diazotiert und sodaalkalisch mit 14 Teilen Salicylsäure kombiniert. Der Farbstoff scheidet sich zum größten Teil aus und wird durch Aussalzen völlig abgeschieden. Getrocknet bildet er ein braunes Pulver, das sich orangefarben in Wasser löst; Auf Zusatz von Natronlauge färbt sich die Lösung blaurot, aufίο o-Aminoazoanisole with low smoking Acid in the cold, in the usual way, with a solution of 7 parts by weight of sodium nitrite diazotized and soda-alkaline combined with 14 parts of salicylic acid. The dye for the most part separates out and is completely separated out by salting out. Dried it forms a brown powder that dissolves in water in an orange color; Upon addition of Caustic soda, the solution turns blue-red
Zusatz von Mineralsäuren gelb. Wolle wird in saurem Bade orange gefärbt. Die Färbung geht beim Nachchromieren in ein gelbliches Rot über.Yellow mineral acids added. Wool is dyed orange in an acid bath. The coloring turns into a yellowish red when chromium plating.
Ersetzt man in obigem Beispiel die Salicylsäure durch die äquivalente Menge einer Kresotinsäure, so erhält man Farbstoffe von ähnlichen Eigenschaften; sowohl die direkte wie auch die mit Chrom nachbehandelte Färbung zeigen gegen den Salicylsäurefarbstoff eine Nuancenverschiebung nach Rot.If in the above example the salicylic acid is replaced by the equivalent amount of a cresotinic acid, thus one obtains dyes with similar properties; both direct and The color after-treated with chromium also shows a resistance to the salicylic acid dye Shift of nuances to red.
