  Verfahren zur Darstellung von 3. 3'-Dichlor-4.4'-dioxy-5.5'-diacetaminoarsenobenzol. 



   In der Patentschrift Nr. 123401 ist die Herstellung des 3.   3'-Dichlor.     41-doxy-   5. 5'-discetaminoarsenobenzols durch Reduktion der 3-Chlor-4-oxy-5-acctaminobenzol-1-arsinsäure beschrieben. Es wurde nun gefunden, dass man auch zu dem gleichen Produkt gelangt, wenn man das von Binz, Bauer und Hallstein beschriebene, durch Reduktion der 3-Chlor-4-oxy-5nitrobenzolarsinsäure crhaltene-3.3'-Dichlor-4.4'-dioxy-5.5'-diaminoarsenobenzol (B. 53   [1920] 422)   nach Ersatz des Wasserstoffes der beiden Hydroxylgruppen durch Alkalimetall nach üblichen Methoden acetyliert.

  Process for the preparation of 3. 3'-dichloro-4.4'-dioxy-5.5'-diacetaminoarsenobenzene.



   In patent specification No. 123401, the preparation of the 3rd 3'-dichloro. 41-doxy-5, 5'-discetaminoarsenobenzene described by reducing 3-chloro-4-oxy-5-acctaminobenzene-1-arsinic acid. It has now been found that the same product is also obtained if the 3.3'-dichloro-4.4'-dioxy-5.5 obtained by reducing the 3-chloro-4-oxy-5nitrobenzolaric acid described by Binz, Bauer and Hallstein '-diaminoarsenobenzene (B. 53 [1920] 422) after replacement of the hydrogen of the two hydroxyl groups by alkali metal acetylated by customary methods.
 EMI1.1
 4. 4'-dioxy-5. 5'-diacetaminoarsenobenzene is filtered off with suction, washed with water and dried in vacuo.
