Description

  

  Verfahren zur Darstellung eines neuen     Anthrachinonderivates.            Cxegenstarrd    vorliegender Erfindung ist  ein Verfahren zerr Darstellung eines neuen       Anthrachinonderivates,    welches darin besteht,  dass man auf     1-Amino-4-bromanthrachinorr-          2-sulfomethyltarrrid        Cyklohexylamin    einwir  ken lässt.    <I>Beispiel:</I>    10 Gewichtsteile     1-Amino-4-bromarrthra-          clrinorr-2-sulfochlorid    werden mit 25 Gewichts  teilen einer 15      /oigen        Methyltaurinkalium-          lösung    in einer Kugelmühle umgesetzt.

   Nach  etwa 20 Stunden wird die dunkelrote Paste       abgesaugt.    Zur Reinigung wird das entstan  dene     Kaliumsalz        1-Amino-4-bromanthra-          chinon-2-sulfomethyltaurid    aus Wasser um  kristallisiert.

   Es wird dabei in sehr kleinen,  kurzen, gedrungenen scharlachroten     Kriställ-          chen    erhalten, die in kaltem Wasser schwer  löslich sind. 6,5 Gewichtsteile des aus Was  ser umkristallisierten     Kaliumsalzes    des 1  Anrino-4-brom-2-sulfomethyltaurids werden    zusammen mit 2 Gewichtsteilen Soda, 100  Gewichtsteilen Wasser, 35 Gewichtsteilen       Cyklohexylamin    und 1 Gewichtsteil     Kupfer-          chlorür    etwa 3 Stunden auf<B>50-60'</B> er  wärmt. Dabei färbt sich die Reaktionsmasse  bald blau.

   Das gebildete Salz des     1-Amino-          4    -     eyklohexylamirroanthrachinon    - 2 -     sulfome-          thyltaurids    wird zweckmässig durch Zusatz  von     Sodalösung    abgeschieden und zur wei  teren Reinigung wiederholt in Wasser gelöst  und mit Soda, Kochsalz oder Chlorammonium  gefällt. Es bildet ein dunkelblaues Pulver,  das Wolle aus saurem Bade blau anfärbt.  Eine heisse wässerige Lösung des Salzes ge  latiniert beim Erkalten.



  Process for the preparation of a new anthraquinone derivative. The present invention is based on a method for the preparation of a new anthraquinone derivative, which consists in allowing cyclohexylamine to act on 1-amino-4-bromoanthraquinor-2-sulfomethyltarrride. <I> Example: </I> 10 parts by weight of 1-amino-4-bromarrthraclrinorr-2-sulfochloride are reacted with 25 parts by weight of a 15% potassium methyl taurine solution in a ball mill.

   After about 20 hours, the dark red paste is suctioned off. For purification, the resulting potassium salt 1-amino-4-bromoanthraquinone-2-sulfomethyltauride is recrystallized from water.

   It is obtained in very small, short, squat, scarlet crystals that are sparingly soluble in cold water. 6.5 parts by weight of the potassium salt of 1 anrino-4-bromo-2-sulfomethyltauride recrystallized from water, together with 2 parts by weight of soda, 100 parts by weight of water, 35 parts by weight of cyclohexylamine and 1 part by weight of copper chlorine for about 3 hours to <B> 50- 60 'he is warming. The reaction mass soon turns blue.

   The salt formed of 1-amino-4-eyklohexylamirroanthraquinone-2-sulfome- thyltaurids is expediently deposited by adding soda solution and repeatedly dissolved in water for further purification and precipitated with soda, table salt or chlorammonium. It forms a dark blue powder that stains wool from an acid bath blue. A hot, aqueous solution of the salt gels when cooled.
