Description
Verfahren zur Herstellung eines Kondensationsproduktes der Ogazinreihe. Vorliegendes Patent bezieht sich auf ein Verfahren zur Herstellung eines Kon densationsproduktes der Ogazinreihe, da durch gekennzeichnet, dass man 1 Mol. Chloranil mit 1 Mol. 4-Methyl-5-nitro-2- aminophenol kondensiert.
Das so erhaltene 1. 3. 4-Trichlor-6-me- thyl-7-nitrophenogazon-2 der Formel:
EMI0001.0010
ist ein neuer Körper. Durch Umkristallisieren aus Essigsäureanhydrid erhält man es in Farm von leuchtend roten Nadeln, die sich in konz. Schwefelsäure mit gelbgrüner Farbe lösen. Das neue Produkt soll als Zwischenpro dukt zur Herstellung von weiteren Farb stoffen, insbesondere von Schwefelfarbstoffen, Verwendung finden.
Beispiel: 28 Teile Chloranil werden mit 16,8 Teilen 4-Methyl-5-nitro-2-aminophenol unter Zusatz von 10 Teilen wasserfreiem Nätriumacetat in <B>50</B> Teilen Alkohol bis zur Beendigung der <B>2</B> Reaktion- gerührt, was nach kurzer Zeit der Fall ist. Das entstandene 1.3.4-Trichlor-6-methyl-7- nitro-phenoaazon-2 ist ausgeschieden;
es wird abgesaugt, mit Alkohol und Wasser gewa schen und getrocknet.
Process for the production of a condensation product of the Ogazine series. The present patent relates to a process for the preparation of a condensation product of the ogazine series, characterized in that 1 mol. Of chloranil is condensed with 1 mol. 4-methyl-5-nitro-2-aminophenol.
The thus obtained 1. 3. 4-trichloro-6-methyl-7-nitrophenogazon-2 of the formula:
EMI0001.0010
is a new body. It is obtained by recrystallization from acetic anhydride in the form of bright red needles which are in conc. Dissolve sulfuric acid with a yellow-green color. The new product is to be used as an intermediate product for the production of other dyes, in particular sulfur dyes.
Example: 28 parts of chloranil are mixed with 16.8 parts of 4-methyl-5-nitro-2-aminophenol with the addition of 10 parts of anhydrous sodium acetate in <B> 50 </B> parts of alcohol until the <B> 2 </ B> reaction - stirred, which is the case after a short time. The resulting 1,3.4-trichloro-6-methyl-7-nitro-phenoaazon-2 is eliminated;
it is suctioned off, washed with alcohol and water and dried.
