Description
Verfahren zur Herstellung einer Anthrachinon-Verbindung. Gemäss vorliegender Erfindung erhält man l.-Amino-4-anilin--2-cetyloxyanthrachi- nondurch Umsetzung des 1-Amino-4-anilido- 2-phenoxyanthrachinons mit einer Alkali metallverbindung des Cetylalkohols.
Die Alkalimetallverbindung selbst kann durch Erhitzen eines Alkalimetallhydroxyds mit Cetylalkohol erhalten werden. Sie kann auch durch Zufügen eines Alkalimetalles zum Cetylalkohol hergestellt werden.
1- Amino - 4 - anilido - 2 - cetyloxyanthra.chi- non wird im Schweizer Patent Nr. 180059 erwähnt, wo es als Ausgangsmaterial zur Farbstoffherstellung benutzt wird.
Beispiel <I>1:</I> 5 Teile 1-Amino-4-anilido,-2-phenoxy- anthrachinon (erhalten durch Erhitzen von 2-Brom-l-amino-4-anilido-anthrachinon mit Natriumphenolat in Phenol), 19 Teile Cetyl- alkohol und 1 Teil Kaliumhydroxyd-Pulver, welches intermediär die Kaliumverbindung des Cetylalkohols ,bildet, werden zusammen während 6 Stunden bei IM' C umgerührt.
50 Teile Äthylalkohol werden zugegeben und unter Kühlen das 1-Amino=4-anilido-2- cetyloxyanthrachinon abgeschieden und ab filtriert, nacheinander mit Äthylalkohol und Wasser gewaschen und getrocknet. <I>Beispiel 2:</I> 1,8 Teile Natrium werden 50 Teilen Cetylalkohol zugesetzt und das Gemisch während 5 Stunden auf<B>UM'</B> C erhitzt, dann auf<B>100'</B> C gekühlt. 18;
5 Teile 1- Amino-4-anilido-2-phenoxyanthrachinon wer den zugefügt und das Gemisch bei<B>100'</B> C so lange umgerührt, bis eine Probe in Li- groin (.Siedepunkt 60 bis<B>80'</B> C) sich voll ständig löst. Dann werden 250 Teile Äthyl- alkohol zugesetzt, das Produkt wird kalt fil triert und mit Äthylalkohol und Wasser ge waschen.
Process for the preparation of an anthraquinone compound. According to the present invention, l-amino-4-aniline-2-cetyloxyanthraquinone is obtained by reacting 1-amino-4-anilido-2-phenoxyanthraquinone with an alkali metal compound of cetyl alcohol.
The alkali metal compound itself can be obtained by heating an alkali metal hydroxide with cetyl alcohol. It can also be made by adding an alkali metal to the cetyl alcohol.
1- Amino - 4 - anilido - 2 - cetyloxyanthra.chinone is mentioned in Swiss patent no. 180059, where it is used as a starting material for the manufacture of dyes.
Example <I> 1: </I> 5 parts of 1-amino-4-anilido, -2-phenoxy-anthraquinone (obtained by heating 2-bromo-1-amino-4-anilido-anthraquinone with sodium phenolate in phenol), 19 parts of cetyl alcohol and 1 part of potassium hydroxide powder, which forms the intermediate potassium compound of cetyl alcohol, are stirred together for 6 hours at IM 'C.
50 parts of ethyl alcohol are added and, with cooling, the 1-amino = 4-anilido-2-cetyloxyanthraquinone is deposited and filtered off, washed successively with ethyl alcohol and water and dried. <I> Example 2 </I> 1.8 parts of sodium are added to 50 parts of cetyl alcohol and the mixture is heated to <B> UM '</B> C, then to <B> 100' </B> for 5 hours C chilled. 18;
5 parts of 1-amino-4-anilido-2-phenoxyanthraquinone are added and the mixture is stirred at 100 ° C until a sample is poured into Ligroin (boiling point 60 to 80 '</B> C) loosens completely. Then 250 parts of ethyl alcohol are added, the product is filtered cold and washed with ethyl alcohol and water.
