Description
Verfahren zur Herstellung eines neuen Farbstoffes. Es wurde gefunden, dass man einen neuen Farbstoff erhält, wenn man den Azofarb- stoff aus Diazoparanitrobenzol und 4-Chlar- o-anisidin weiter diazotiert und mit Mono- äthyl-a-naphthylamin kuppelt. Der neue Farbstoff bildet ein schwärzliches Pulver, das sich in Eisessig mit tiefroter, in Schwe felsäure mit grünschwarzer Farbe löst.
Auf einer geeigneten Unterlage, zum Beispiel Azetylzellulose, hergestellt, färbt er diese in echten tiefschwarzen Tönen an.
<I>Beispiel:</I> 306 Teile des Farbstoffes aus Diazopara- nitrobenzol und 4-Chlor-o-anisidin werden wie üblich mit 69 Teilen Nitrit diazotiert und unter Rühren in eine wässerige Suspen sion von 207 Teilen Monoäthyl-a-naphthyl- aminchlorhydrat eingetragen. Nach einiger Zeit wird der gebildete Farbstoff filtriert. mit .verdünntem Ammoniak durchgerührt, nochmals filtriert und getrocknet.
Process for the production of a new dye. It has been found that a new dye is obtained if the azo dye from diazoparanitrobenzene and 4-chloro-o-anisidine is further diazotized and coupled with monoethyl-a-naphthylamine. The new dye forms a blackish powder that dissolves in glacial acetic acid with a deep red color and in sulfuric acid with a greenish black color.
Produced on a suitable base, for example acetyl cellulose, it stains it in real deep black tones.
<I> Example: </I> 306 parts of the dye from diazopara- nitrobenzene and 4-chloro-o-anisidine are diazotized as usual with 69 parts of nitrite and, with stirring, in an aqueous suspension of 207 parts of monoethyl-a-naphthyl- amine chlorohydrate registered. After some time, the dye formed is filtered off. Stirred with .dünntem ammonia, filtered again and dried.
