Description

  

  Verfahren zur Darstellung eines     Gemisehes    von<B>in</B> Wasser löslichen Arsenverbindungen.    Es wurde gefunden, dass man zu einem  Gemisch von wasserlöslichen Arsenverbin  dungen von vorzüglichen Eigenschaften ge  langt, wenn man     Epihydrinalkohol    auf     4'4-          Di,dimdthylamiino-3'        3-,diamino-        p,        arsenobenzol     einwirken lässt. Die erhaltene     Substanz    ist  gelb und in Wasser leicht löslich.  



       Beispiel:     39,2     gr        4'4-Didimethylamino-3'3-diamino-          p-arsenobenzol    werden mit 17     gr        Epihydrin-          alkohol    in 50 cm' Methylalkohol eingetragen.  Nach eingetretener Lösung der Base wird mit  Alkohol und Äther ausgefällt; das Reaktions  produkt aus 4'4-Didimethylamino-ä'3-ce-         amino-p-arsenobenzol    und     Epihydrinalkohol          wird    abgesaugt. Die erhaltene Substanz ist  gelb und in Wasser leicht     löslich.  



  Process for the preparation of a mixture of <B> water-soluble arsenic compounds. It has been found that a mixture of water-soluble arsenic compounds of excellent properties is obtained if epihydrin alcohol is allowed to act on 4'4-di, dimdthylamiino-3 '3-, diamino-p, arsenobenzene. The substance obtained is yellow and easily soluble in water.



       Example: 39.2 g of 4'4-didimethylamino-3'3-diamino-p-arsenobenzene are added to 50 cm 'of methyl alcohol with 17 g of epihydrin alcohol. After the base has dissolved, it is precipitated with alcohol and ether; the reaction product of 4'4-didimethylamino-3-ce- amino-p-arsenobenzene and epihydrin alcohol is filtered off with suction. The substance obtained is yellow and easily soluble in water.
