Description
Verfahren zur Herstellung eines braunen Nüpenfarbstoffes der Anthanthronreihe. Vorliegendes Patent bezieht sich auf ein Verfahren zur Herstellung eines braunen Kii- penfarbstoffes der Anthanthronreihe von der wahrscheinlichen Formel:'
EMI0001.0006
dadurch gekennzeichnet, dass man Dibrom- anthanthron mit der diniolekularen Menge 1-Amino-anthrachinon-2-aldehyd bei höherer Temperatur zur Umsetzung bringt.
Der Farb stoff löst sich in konzentrierter Schwefelsäure mit roter, in heissem Nitrobenzol mit brauner Farbe. Er färbt Baumwolle aus rotvioletter Hydrosulfitküpe in rotbraunen echten Tönen an. Beispiel: 4,6 Teile Dibrom-anthanthron (vergl. Schweizerisches PatentNr.130618) und 5 Teile 1-Amiiio-anthrachinoii-2-aldehyd werden in 200 Teilen Naphthalin unter Zusatz von 4 Teilen wasserfreiem Natriumacetat und 0,5 Teilen Kupferchlorür einige Stunden unter Rückfluss gekocht.
Die noch warme Schmelze wird mit Naphtha verdünnt, abgesaugt, mit Naphtha, darin mit Spiritus und heissem, ganz verdünntem Ammoniak gewaschen und getrocknet.
Process for the production of a brown nub dye of the anthanthrone series. The present patent relates to a process for the production of a brown box dye of the anthanthrone series of the probable formula: '
EMI0001.0006
characterized in that dibromanthanthrone is reacted with the dinolecular amount of 1-amino-anthraquinone-2-aldehyde at a higher temperature.
The dye dissolves in concentrated sulfuric acid with a red color and in hot nitrobenzene with a brown color. He dyes cotton from red-violet hydrosulfite vat in red-brown real tones. Example: 4.6 parts of dibromo-anthanthrone (see Swiss Patent No. 130618) and 5 parts of 1-Amiiio-anthraquinone-2-aldehyde are added to 200 parts of naphthalene with 4 parts of anhydrous sodium acetate and 0.5 part of copper chloride for a few hours Boiled under reflux.
The still warm melt is diluted with naphtha, filtered off with suction, washed with naphtha, then with spirit and hot, completely diluted ammonia and dried.
