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.
