Description

  

  Verfahren mir Darstellung     eines        IKfipenfarbstoffes.            lm    Hauptpatent ist ein     Verfahren    zur  Darstellung eines     Küpenfarbstoffes    beschrie  ben, bei dem     Anthanthron    mit jodierenden  Mitteln behandelt wird.  



  Es wurde nun gefunden, dass man einen  Farbstoff von ähnlichen Eigenschaften er  halten kann, wenn man     Monobromarrthan-          thron,    erhalten z.     B.    durch     Biomieren    von       Anthanthron    oder durch Überführen von       Monoaminoanthanthron    nach     Sandrneyer    in       Bromanthanthron,        jodiert.     



  Der erhaltene     Farbstoff,    ein     Bromjod-          anthanthron,    stimmt in seinen Eigenschaften  mit dem des gemäss dem Schweiz. Patent  Nr. 149901 erhaltenen     Farbstoff        überein.     



  <I>Beispiel:</I>  76 Teile     Monobromanthanthron    (darge  stellt durch     Diazotieren    von     Monoaminoanth-          anthron    und Ersatz der     Diazogruppe    durch  Brom nach     Sandmeyer    mittelst     Kupferbromür)       werden in<B>360</B> Teilen     lllonohydrat    gelöst und  mit 26 Teilen Jod jodiert.

   Nach     Beendigung     der Reaktion     @.vird    das gebildete     Bromjod-          anthanthron    durch Zugabe vorn verdünnter  Schwefelsäure oder Eis in Form seines Sul  fates abgeschieden, abgesaugt und dieses in  der     üblichen    Weise mit Wasser zersetzt.



  Method with representation of an IKfipen dye. The main patent describes a process for preparing a vat dye in which anthanthrone is treated with iodine agents.



  It has now been found that you can keep a dye of similar properties, if you get Monobromarrthan- thron, z. B. by biomizing of anthanthrone or by converting monoaminoanthanthrone to Sandrneyer in bromanthanthron, iodized.



  The dye obtained, a bromoiodanthanthrone, has the same properties as that of Switzerland. U.S. Patent No. 149901.



  <I> Example: </I> 76 parts of monobromoanthanthrone (represented by diazotizing monoaminoantanthanthrone and replacing the diazo group by bromine according to Sandmeyer using copper bromur) are dissolved in <B> 360 </B> parts of ilonohydrate and 26 parts of iodine iodized.

   After the end of the reaction, the bromoiodanthanthrone formed is separated out in the form of its sulphate by adding dilute sulfuric acid or ice, filtered off with suction and this is decomposed with water in the usual way.

PATENTANSPRUCH: Verfahren zur Darstellung eines Kül>en- farbstoffes, dadurch gekennzeichnet, da( man Dlonobromanthauthron, wie es durch Biomieren von Anthanthron erhalten werden kann, mit jodierenden Mitteln behandelt. Der erhaltene Farbstoff, ein Bromjod anthanthron, stimmt mit seinen Eigenschaften mit dem des gemäss dein Schweiz. Patent Nr. 149901 erhaltenen Farbstoff überein. PATENT CLAIM: Process for the preparation of a coolant dye, characterized in that (dlonobromanthrone, as it can be obtained by biomizing anthanthrone, is treated with iodising agents. The obtained dye, a bromiodine anthanthrone, has the same properties as those of the des according to Swiss Patent No. 149901.
