EMI1.2
lang in wässeriger Lösung, auch an der Luft haltbar ist. ohne auszufallen, ohne eine Zunahme der Giftigkeit zu erfahren oder an therapeutischer Wirkamkeit einzubüssen. Diese Lösung ist darum von praktiseher Bedeutung und stellt einen technischen und therapeutischen Fortschritt dar.
Auch wenn man die Silververbindung des 4,4'-Dioxy-3,3'-diaminoarsnobenzolantriums durch das natriumsalz des Dioxydiaminoarsenobenzols ersetzt verläuft die Reaktion in gleicher Richtung, wie daraus ersieht- lieh-ist. dass beim Einleiten von Kohlendioxyd in das Reaktionsgemisch kein Dioxydiaminoarsenobenzol
EMI1.3
mit Kochsalz keinen Niederschlag, woraus ebenfalls hervorgeht, dass die Silberverbindung des 4. 4'-Dioxy- 3. 3'-diaminoarsenobenzolnatriums nicht mehr als solches vorhanden, sondern in Reaktion gegangen ist, denn dieses fällt mit ('hlornatrium aus, wenn eine Lösung davon einige Zeit. gestanden hat.
EMI1.4

EMI1.1
EMI1.2
long in aqueous solution, can also be kept in air. without failing, without experiencing an increase in toxicity or losing therapeutic effectiveness. This solution is therefore of practical importance and represents a technical and therapeutic advance.
Even if the silver compound of 4,4'-dioxy-3,3'-diaminoarsnobenzolantrium is replaced by the sodium salt of dioxydiaminoarsenobenzene, the reaction proceeds in the same direction, as can be seen from it. that when introducing carbon dioxide into the reaction mixture, no dioxydiaminoarsenobenzene
EMI1.3
no precipitate with sodium chloride, which also shows that the silver compound of 4, 4'-dioxy-3, 3'-diaminoarsenobenzene sodium is no longer present as such, but has reacted, because this precipitates with ('sodium sodium when a solution of which has stood for some time.
EMI1.4
arsenobenzene has united.
