Description
Verfahren zur Darstellung einer auf die Baumwolle ziehenden und auf der Faser diazotierbaren Verbindung. Das den Gegenstand vorliegender Erfin dung bildende Verfahren ist dadurch gekenn zeichnet, dass man aus zwei Molekülen 1- For mylatnino-4-(4'-n itrobenzoylamino)-benzol- 3-sulfosäure
EMI0001.0008
durca vorsichtige Reduktion der beiden Nitro- grupl-en, wobei Bindung zwischec14den Stick- stof'a''vomenstattfie-d:
et, und darauffolgendeAb- spaltung des Am eisensäurerestes eine schwach gelb gefärbte Verbindung herstellt, die als Natriumsalz in Wasser leicht löslich ist und aus der wässerigen Lösung mit blassgelber Farbe auf Baumwolle zieht.
Durch Diazotieren auf der Faser und Kuppeln mit 1-Phenyl-3- methyl-5-pyrazolon erhält man ein kräftiges, lebhaftes grünstichiges Gelb von sehr guter Wasch- und Lichtechtbeit. <I>Beispiel:</I> 38,7 Teile 1-formylamino-4-(4'-nitrobenzoyl- amino)-benzol-3-sulfosaures Natrium, erhalten aus4-Amino-l-formylaminobenzol-3-sulfosäure , und 4-Nitrobenzoylchlorid, werden in 1000 Teilen Wasser gelöst. Man setzt bei 20 7,8 Teile wasserfreies Natriumsulfid zu und verfährt gemäss Beispiel 1 des Hauptpatentes.
Das Reaktionsprodukt wird durch kurzes Kochen mit 1/2 bis 1 /o iger Natriumhydroxyd- lösung verseift.
Process for the preparation of a compound which pulls on the cotton and can be diazotized on the fiber. The method forming the subject of the present invention is characterized in that 1- For mylatnino-4- (4'-n itrobenzoylamino) -benzene-3-sulfonic acid is made from two molecules
EMI0001.0008
by cautious reduction of the two nitro groups, whereby binding between the nitrogen takes place:
et, and the subsequent cleavage of the amic acid residue produces a pale yellow colored compound which, as the sodium salt, is easily soluble in water and from the aqueous solution draws a pale yellow color onto cotton.
Diazotization on the fiber and coupling with 1-phenyl-3-methyl-5-pyrazolone gives a strong, vivid greenish yellow with very good wash and lightfastness. <I> Example: </I> 38.7 parts of 1-formylamino-4- (4'-nitrobenzoyl-amino) -benzene-3-sulfonic acid sodium, obtained from 4-amino-1-formylaminobenzene-3-sulfonic acid, and 4 -Nitrobenzoyl chloride are dissolved in 1000 parts of water. 7.8 parts of anhydrous sodium sulfide are added at 20 and the procedure is as in Example 1 of the main patent.
The reaction product is saponified by briefly boiling with 1/2 to 1 / o strength sodium hydroxide solution.
