Description
Verfahren zur Herstellung eines neuen Kondensationsproduktes der Naphthochinoniminreihe. Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung eines neuen Kondensationsproduktes der Naphthoehinon- iminreihe, das dadurch gekennzeichnet ist., dass man 3,7-Dibrom-5-amino-8-oxy-1,4-naph- t.hoehinonimin-(l.) in Gegenwart eines Lö- sungsmittels mit p-Amino-azobenzol konden siert.
<I>Beispiel:</I> 87 Teile feingepulvertes 3,7-Dibroin-5- acnino-8-oxy-1,4-naphtliochinonimin-(l) wer den in 300 Teilen Eisessig angerührt. Man tränt nach einer halben Stunde 50 Teile 4 Amino-azobenzol ein und erhitzt kurze Zeit auf 900. Hierauf lässt man erkalten und fil triert. Der Rückstand wird mit Wasser essig säurefrei gewaschen. Er löst sich grün in Al- kohol, gelbgrün in konzentrierter Schwefel säure und auf Zusatz von Formaldehyd grün. Das Produkt soll als Zwischenprodukt oder als Farbstoff Verwendung finden.
Process for the preparation of a new condensation product of the naphthoquinone imine series. The subject of the present patent is a process for the preparation of a new condensation product of the naphthoehinonimine series, which is characterized in that 3,7-dibromo-5-amino-8-oxy-1,4-naph- t.hoehinonimin- ( l.) in the presence of a solvent with p-amino-azobenzene condenses.
<I> Example: </I> 87 parts of finely powdered 3,7-dibroin-5-acnino-8-oxy-1,4-naphthiochinonimine (l) are mixed in 300 parts of glacial acetic acid. After half an hour, 50 parts of 4-amino-azobenzene are soaked in and heated to 900 for a short time. This is then allowed to cool and filter. The residue is washed acid-free with water, acetic acid. It dissolves green in alcohol, yellow-green in concentrated sulfuric acid and green when formaldehyde is added. The product is intended to be used as an intermediate or as a dye.
