Description
Zusatzpatent zum Hauptpatent Nr. 208544. Verfahren zur Herstellung eines stickstoffhaltigen Kondensationsproduktes. Es wurde gefunden, dass man ein stick- stoffhaltiges herstel len kann, wenn man 1 Mol 1,3-Dihalegen-2- methylanthrachinon mit 2 Mal 1-Amino-5- benzoylaminoanthrachinon umsetzt. Der neue Farbstoff ist ein,dunkelbraunes Pulver,
das sich in Schwefelsäure mit braunoliver Farbe löst und Baumwolle aus brauner Küpe in echten braunen Farbtönen färbt.
Als 1,3-Dihalogen-2-methylanthrachinon kann beispielsweise 1,3-Dichlor-2-methyl- anthrachinon verwendet werden.
Die Umsetzung mit 1-Amino:-5-benzoyl- aminoanthrachinon erfolgt zweckmässig in Gegenwart von Lösungs- oder Verteilungs- mitteln, z. B. Nitrobenzol, Dichlarbenzol oder Naphthalin und in Gegenwart von Katalysa toren, wie Kupfer oder Kupferverbindungen, sowie vorzugsweise in Anwesenheit von säurebindenden Mitteln, wie Natriumacetat und Alkalicarbonat, bei höherer Temperatur.
Beispiel: 14,5 Teile 1,3-Dichlor-2-methylanthra- ehinon, 34,5 Teile 1-Amino 5-benzoylamino- anthrachinon, 40 Teile wasserfreies Natrium carbonat, 1 Teil Kupferacetat und 300 Teile Naphthalin werden 18 Stunden zum Sieden erhitzt.
Das Reaktionsgemisch wird noch heiss mit 300 Teilen Chlorbenzol verdünnt und bei 90-100 filtriert. Der Rückstand wird mit Chlorbenzol sowie mit Alkohol ge waschen, mit Wasser ausgekocht, filtriert und getrocknet.
Additional patent to main patent No. 208544. Process for the production of a nitrogen-containing condensation product. It has been found that a nitrogen-containing one can be produced if 1 mole of 1,3-dihalogen-2-methylanthraquinone is reacted with 2 times 1-amino-5-benzoylaminoanthraquinone. The new dye is a dark brown powder
which dissolves in sulfuric acid with a brown-olive color and dyes cotton from a brown vat in real brown shades.
1,3-dichloro-2-methyl-anthraquinone, for example, can be used as 1,3-dihalo-2-methylanthraquinone.
The reaction with 1-amino: -5-benzoylaminoanthraquinone is expediently carried out in the presence of solvents or distributing agents, e.g. B. nitrobenzene, dichlorobenzene or naphthalene and in the presence of cata factors, such as copper or copper compounds, and preferably in the presence of acid-binding agents such as sodium acetate and alkali metal carbonate, at a higher temperature.
Example: 14.5 parts of 1,3-dichloro-2-methylanthraquinone, 34.5 parts of 1-amino 5-benzoylamino anthraquinone, 40 parts of anhydrous sodium carbonate, 1 part of copper acetate and 300 parts of naphthalene are heated to the boil for 18 hours .
The reaction mixture is diluted while still hot with 300 parts of chlorobenzene and filtered at 90-100. The residue is washed with chlorobenzene and with alcohol, boiled with water, filtered and dried.
