   Der auf gleiche Weise aus 1-Chlor-4-benzoylaminoanthrachinon erhaltene Körper kristallisiert in roten Nadeln und färbt Baumwolle rot an. Aus 1-Benzoylamino-6-chloranthrachinon erhält man einen sehr kräftigen gelben Küpenfarbstoff von hervorragenden Echtheitseigenschaften. 



   Ganz analog verhalten sich andere Halogenanthrachinonderivate sowie die Alkalisalze anderer Abkömmlinge der Thiokohlensäure.

  Process for the preparation of sulfur-containing anthraquinone derivatives.



   It was found that by the action of thiocarbonic acid derivatives, e.g. B. xanthates, tritbiocarbonates or similarly acting substances on halantbrachinones and their derivatives leads to new products which are of major technical importance as dyes or as starting materials for the preparation of such substances.



  The reaction is expediently carried out in a suitable solvent.



   Example 1.



   15 parts of a-chloranthraquinone and 15 parts of trithiocarbonate of soda (or potash) are heated in 100 parts of nitrobenzene (or another high-boiling solvent) for two to three hours for about 1400 (or one hour to boil). It is allowed to cool, filtered off with suction, washed with Alcohol and water. When dried, the body is a yellow crystal powder that dissolves in concentrated sulfuric acid with an olive color.

 one holds an orange-colored body that dyes cotton in vivid red-yellow tones from the vat. The analogous product from 1-benzoylamino-6-chloroanthraquinone has a strong color

   15 parts of ß-chloranthraquinone in 120 parts of xitrobenzene are heated to 120 to 1300 and slowly 10 parts of @anthogensaures potash are introduced. After the reaction has ended, the mixture is left to cool, filtered off with suction, washed with alcohol and water. That after

 and turns an intense orange.



   The body obtained in the same way from 1-chloro-4-benzoylaminoanthraquinone crystallizes in red needles and stains cotton red. A very strong yellow vat dye with excellent fastness properties is obtained from 1-benzoylamino-6-chloroanthraquinone.



   Other halogenanthraquinone derivatives and the alkali salts of other derivatives of thiocarbonic acid behave in a completely analogous manner.
