Description
Verfahren zur Darstellung eines echten Küpenfarbstoffes. Die Erfindung beruht auf der Beobach tung, dass die Thioderivate der p-Chitione und ihre Halogensubstitutionsprodukte (be schrieben im deutschen Patent Nr. 175070) sich auch mit zwei verschiedenen Arylaminen zu besonders zum Färben der tierischen Faser geeigneten wertvollen Küpenfarbstoffen kondensieren lassen.
Gegenstand des vorlie genden Patentes ist nun .ein Verfahren zur Darstellung eines echten Küpenfarbstoffes, wonach man Chinonmonothiosulfosäure in in differenten Medien bei niederer Temperatur zunächst mit . Metatoluidin zu einem Mono kondensationsprodukt kondensiert und hier auf dieses mit p-Chloranilin zu einem ge mischten Kondensationsprodukt vereinigt. Beispiel: 26 kg cbinoninonothiosulfosaures Kalium werden in ungefähr 1000 Liter Wasser bei gewöhnlicher Temperatur gelöst, hierzu gibt man unter gutem Rühren eine Lösung von 5,3 kg m-Toluidin in 12 kg Eisessig.
Die Bildung des Kondensationsproduktes beginnt sofort und ist nach einigen Stunden Rührens beendet; dasselbe bleibt mit kirschroter Farbe in Lösung. Man fügt dann eine Lösung von 4 kg p-Chloranilin in 10 kg Eisessig zu und setzt das Rühren bei gewöhnlicher Tempe ratur so lange fort, bis die Bildung des ge mischten Kondensationsproduktes beendet ist. Dasselbe ist nach fertiger Bildung zum Teil ausgeschieden; man salzt aus, filtriert und wäscht das Filtergut mit verdünntem Salz wasser. Der so gewonnene Farbstoff färbt Wolle in der Küpe echt gelb.
Process for the preparation of a real vat dye. The invention is based on the observation that the thio derivatives of the p-chitione and their halogen substitution products (described in German Patent No. 175070) can also be condensed with two different arylamines to give valuable vat dyes, which are particularly suitable for dyeing animal fibers.
The subject of the present patent is now .ein a method for the preparation of a real vat dye, after which one quinone monothiosulfonic acid in different media at low temperature initially with. Metatoluidine condensed to a mono condensation product and here combined with p-chloroaniline to form a mixed condensation product. Example: 26 kg of cbinoninonothiosulphonic acid potassium are dissolved in approximately 1000 liters of water at normal temperature, to this a solution of 5.3 kg of m-toluidine in 12 kg of glacial acetic acid is added with thorough stirring.
The formation of the condensation product begins immediately and ends after a few hours of stirring; the same remains in solution with cherry red color. A solution of 4 kg of p-chloroaniline in 10 kg of glacial acetic acid is then added and stirring is continued at the usual temperature until the formation of the mixed condensation product has ended. The same is partly eliminated after it has been educated; it is salted out, filtered and the filter material is washed with dilute salt water. The dye obtained in this way dyes wool in the vat really yellow.
