Description
KAISERLICHESIMPERIAL
Es wurde gefunden, daß sich die im Arylrest durch die Aminogruppe substituierten 3"Oxy(i)thionaphtene bzw. deren Carbonsäuren, welche aus den Aminosubstitutionsprodukten der Arylthioglykol-o-carbonsäuren durch Kondensation mit Alkalihydraten erhältlich sind, mit Isatin zu neuen Küpenfarbstoffen kondensieren lassen. So liefert z.B. das leicht zugängliche 6-Amino-3-oxy(i)thionaphten: .It was found that those in the aryl radical were substituted by the amino group 3 "Oxy (i) thionaphtenes or their carboxylic acids, which can be obtained from the amino substitution products of the arylthioglycol-o-carboxylic acids by condensation with alkali hydrates condense with isatin to form new vat dyes. For example, the easily accessible 6-amino-3-oxy (i) thionaphtene:.

bzw. die entsprechenden Carbonsäuren beim Erhitzen mit Isatin in Eisessiglösung einen Küpenfarbstoff, welcher Wolle in leuchtend gelborangefarbenen Tönen, Baumwolle dagegen merklich schwächer, in rötlichbräunliehen Tönen anfärbt. Das 5 - Amino-3-oxy(i)thionaphten bzw. dessen Carbonsäure liefert mit Isatin hingegen einen Küpenfarbstoff, welcher auf Wolle in rötlichgrauen Tönen färbt.or the corresponding carboxylic acids when heated with isatin in glacial acetic acid solution Vat dye, which is wool in bright yellow-orange tones, cotton on the other hand noticeably weaker, colored in reddish-brown tones. The 5-amino-3-oxy (i) thionaphtene or its carboxylic acid, however, provides a vat dye with isatin, which dyes on wool in reddish gray tones.
Beispiel: 16,5Teile 6-Amino-3-oxy(i)thiqnaphten werden in der 20 fachen Menge Eisessig gelöst und mit 15 Teilen Isatin am Rückflußkühler erhitzt. Der Farbstoff scheidet sich hierbei allmählich als dunkelrotes sandiges Pulver aus. Nach dem Absaugen und Waschen mit Wasser stellt derselbe ein dunkelrotes Pulver dar, welches in der Küpe die zuvor bezeichneten Eigenschaften zeigt.Example: 16.5 parts of 6-amino-3-oxy (i) thiqnaphtene are dissolved in 20 times the amount of glacial acetic acid and 15 parts of isatin am Heated reflux condenser. The dye gradually separates out as a dark red sandy one Powder off. After suctioning off and washing with water, it turns out to be a dark red powder, which is in the vat shows previously identified properties.
An Stelle des 6-Amino-3-oxy(i)thionaphtens lassen sich auch dessen Acidylderivate verwenden. Instead of 6-amino-3-oxy (i) thionaphthene, its acidyl derivatives can also be used.
Bei der Herstellung des Farbstoffs aus 5-Amino-3-oxy(i)thionaphten verfährt man genau in derselben Weise. Derselbe zeigt die vorbeschriebenen Eigenschaften.The same procedure is used to prepare the dye from 5-amino-3-oxy (i) thionaphtene exactly in the same way. It shows the properties described above.
