Description
Verfahren zur Herstellung des Wismutsalzes einer 9.rsenoverbiudung. Gegenstand dervorliegender Erfindung ist ein Verfahren zur Herstellung des Wismutsalzes einer Arsenoverbindung, das dadurch gekenn zeichnet ist, dass man 3,3'-dichlor-4-oxy-5,5'- di(acetylamino) - arsenobenzol- 4'- oxyessigsau- res Natrium in wässeriger Lösung mit einem Wismutsalz umsetzt und die ausgeschiedene neue Wismutverbindung abfiltriert.
Das neue Verfahrensprodukt ist ein bräun lichgelbes Pulver, das in Wasser unlöslich, in Alkalien löslich ist. Aus der alkalischen Lösung kann das Natriumsalz mit Alkohol oder Äther ausgefällt werden. Das Produkt soll als Arzneimittel Verwendung finden.
<I>Beispiel:</I> 6gr 3,3'-dichlor-4-oxy-5,5'-di(acetylamino)- arseno-benzol-4'-oxysaures Natrium, herge stellt nach Patent Nr. 159590, werden in 100 cms Wasser gelöst und mit einer wässe- rigen Lösung von 4,8 gr Wismutnitrat um gesetzt, worauf sich die Wismutverbindung als gelb gefärbter Brei abscheidet, der mit Alkohol und Äther gewaschen werden kann.
Das neue Verfahrensprodukt ist ein bräun lichgelbes Pulver, das in Wasser unlöslich, in Alkalien löslich ist. Aus der alkalischen Lösung kann das Natriumsalz mit Alkohol oder Äther ausgefällt werden.
Process for the production of the bismuth salt of a 9th arsenic compound. The present invention relates to a process for the production of the bismuth salt of an arsenic compound, which is characterized in that 3,3'-dichloro-4-oxy-5,5'-di (acetylamino) arsenobenzene-4'-oxyacetic acid is added Reacts sodium in aqueous solution with a bismuth salt and the separated new bismuth compound is filtered off.
The new process product is a brownish yellow powder that is insoluble in water and soluble in alkalis. The sodium salt can be precipitated from the alkaline solution with alcohol or ether. The product is intended to be used as a medicinal product.
<I> Example: </I> 6gr 3,3'-dichloro-4-oxy-5,5'-di (acetylamino) - arsenobenzene-4'-oxyacid sodium, manufactured according to patent no. 159590 dissolved in 100 cms of water and reacted with an aqueous solution of 4.8 g of bismuth nitrate, whereupon the bismuth compound separates out as a yellow colored paste which can be washed with alcohol and ether.
The new process product is a brownish yellow powder that is insoluble in water and soluble in alkalis. The sodium salt can be precipitated from the alkaline solution with alcohol or ether.
