Description
Verfahren zur Darstellung eines sauren Wollfarbstoffes. Im Hauptpatent Nr. 141320 ist ein Ver fahren beschrieben, saure Wollfarbstoffe darzustellen durch Kondensation von Sulfo- säuren, Nitro- und Aminosulfosäuren, ferner Sulfaminsäuren von Naphtalsäureanhydrid mit Ammoniak, aliphatischen oder aromati schen Aminen oder durch Überführen der Umsetzungsprodukte von \ aphtalsäure- anhy drill oder dessen Derivaten mit Am moniak,
aliphatischen oder aromatischen Aminen in Sulfosä.uren oder Sulfaminsäuren, oder ferner durch Kondensation von Naph- talsäureanhydrill oder dessen Derivaten mit Sulfosäuren von Aminen.
Bei der weiteren Ausarbeitung dieser Er findung wurde nun gefunden, dass man zu ähnlichen oder gleichen sauren Farbstoffen gelangt, wenn man Halogensulfonaphtal- säureanhydride oder Derivate vom allge meinen Typ:
EMI0001.0021
wobei sowohl das Halogen, als auch die Sulfogruppe in verschiedenen Stellungen des 11folehiils stehen können, mit Ammoniak, aliphatischen oder aromatischen Aminen um setzt.
Es entstehen hierbei saure Wollfarb- stoffe von gutem Egalisierungsvermögen und sehr klaren Farbtönen vom grünstickig- sten Gelb bis zum rotstickigsten Orange von vermutlich folgender Konstitution:
EMI0001.0030
wobei X M'asserstoff, Alkyl, Aralkyl oder Aryl bedeutet.
Gegenstand dieses Zusatzpatentes ist ein erfahren zur Darstellung eines sauren Wollfarbstoffes, welches dadurch gekenn zeichnet ist, dass man Sulfo-4-bromnaphtal- säureanhvdrid mit Ammoniak umsetzt.
<I>Beispiel:</I> 40 Gewichtsteile Sulfo - 4 - bromnaphtal- säureanhydrid (erhalten durch Sulfieren von 4 - Bromnaphtalsäureanhydrid) werden mit 200 Raumteilen Ammoniak im Autoklaven auf 110 C bis 120 C erhitzt. Nach beende ter Umsetzung wird heiss abgesaugt, das überschüssige Ammoniak vertrieben und der gebildete Farbstoff in üblicher Weise aus gesalzen. abgesaugt und getrocknet; er färbt die tierische Faser aus saurem Bade klar gelb.
Process for the preparation of an acidic wool dye. In the main patent No. 141320 a process is described to produce acidic wool dyes by condensation of sulfonic acids, nitro and aminosulfonic acids, also sulfamic acids of naphthalic anhydride with ammonia, aliphatic or aromatic amines or by converting the reaction products of \ aphtalsäure- anhy drill or its derivatives with ammonia,
aliphatic or aromatic amines in sulfonic acids or sulfamic acids, or furthermore by condensation of naphthalic anhydride or its derivatives with sulfonic acids of amines.
In the further elaboration of this invention it has now been found that similar or identical acidic dyes are obtained if halosulfonaphthalic anhydrides or derivatives of the general type are used:
EMI0001.0021
where both the halogen and the sulfo group can be in different positions of the foil, reacts with ammonia, aliphatic or aromatic amines.
The result is acidic wool dyes with good leveling power and very clear shades from the greenest yellow to the redest orange, presumably of the following constitution:
EMI0001.0030
where X denotes hydrogen, alkyl, aralkyl or aryl.
The subject of this additional patent is an experience for the representation of an acidic wool dye, which is characterized in that sulfo-4-bromonaphthalic anhydride is reacted with ammonia.
<I> Example: </I> 40 parts by weight of sulfo - 4 - bromonaphthalic anhydride (obtained by sulfonating 4 - bromonaphthalic anhydride) are heated with 200 parts by volume of ammonia in an autoclave to 110 ° C to 120 ° C. After the end of the reaction, it is suctioned off hot, the excess ammonia is driven off and the dye formed is salted out in the usual way. vacuumed and dried; it colors the animal fibers from acid baths clear yellow.
