Description
Verfahren zur Darstellung eines wasserlöslichen Antimonsalzes. Das vorliegende Verfahren betrifft die Darstellung von bis jetzt unbekanntem Na triumantimonyl-V-gluconat und ist dadurch gekennzeichnet, dass man Antimonsäure. Gluconsäure und Natriumhydroxyd in Lö sung aufeinander einwirken lässt.
Die neue Verbindung soll zu therapeu tischen Zwecken Verwendung finden. <I>Beispiel:</I> Eine Lösung von 20 gr Natriumgluconat, dargestellt durch Neutralisieren von Glucon- säure mit Natronlauge, in 40 cm' Wasser wird auf dem Dampfbad mit -25 gr Anti- monsäure, die durch Zersetzen von Antimon- pentachlorid mit Wasser erhalten wurde, be handelt. Es entsteht eine trübe Lösung, welche durch Zentrifugieren und Filtrieren geklärt wird.
Aus dieser Lösung wird durch Versetzen mit viel Methylalkohol (etwa 300 cm') Natriumantimonyl-V-gluconat in Form eines farblosen Pulvers ausgeschieden.
Das ausgeschiedene, mit Methylalkohol und Äther gewaschene und hierauf getrock- nete Pulver ist nicht hygroskopisch und in Wasser leicht löslich. Säuren und Alkalien fällen auch in der Siedehitze keine unlös lichen Produkte aus. Schwefelwasserstoff fällt rotes Antimonsulfid.
Process for the preparation of a water-soluble antimony salt. The present method relates to the preparation of previously unknown sodium antimonyl V-gluconate and is characterized in that one antimonic acid. Lets gluconic acid and sodium hydroxide interact in solution.
The new connection is intended to be used for therapeutic purposes. <I> Example: </I> A solution of 20 grams of sodium gluconate, represented by neutralizing gluconic acid with caustic soda, in 40 cm 'of water is poured on the steam bath with -25 grams of antimonic acid, which is produced by the decomposition of antimony pentachloride was obtained with water, be treated. A cloudy solution is created, which is clarified by centrifugation and filtration.
Sodium antimonyl V-gluconate is excreted in the form of a colorless powder from this solution by adding a lot of methyl alcohol (about 300 cm ').
The precipitated powder, washed with methyl alcohol and ether and then dried, is not hygroscopic and easily soluble in water. Acids and alkalis do not precipitate any insoluble products, even at the boiling point. Hydrogen sulfide precipitates red antimony sulfide.
