Description

Verfahren zur Herstellung eines wasserlöslichen Silbersalzes der Acetvlsalicvlsäure Gegenstand des Patents 624o61 ist ein Verfahren, bei dem das schwer lösliche Silbersalz der Aeetylsalicyisäure mit Hexamethylentetramin in Lösung gebracht wird. Es wurde nun gefunden, äaß man zur gleichen Verbindung gelangt, wenn man berechnete Mengen frisch gefälltes Silberoxyd in eine wässerige Lösung von aeetylsalicylsaurem Hexamethylentetramin unter ständigem Rühren einträgt. Die Lösung wird nach dem Filtrieren im Vakuum zur Trockne gebracht. B eis p iel io Teile Aee.tylsalicylsäure werden mit 144 Teilen Hexamethylentetramin in 5oo Teilen destilliertem Wasser gelöst und in diese Lösung unter ständigem Rühren 8 Teile frisch gefälltes Silberoxyd eingetragen. Nach dem Filtrieren wird die Lösung im Vakuum zur Trockne gebracht.Process for the preparation of a water-soluble silver salt of acetyl salicvic acid The subject of patent 624o61 is a process in which the sparingly soluble silver salt the Aeetylsalicyisäure is brought into solution with hexamethylenetetramine. It was now found that one arrives at the same connection if one calculates quantities freshly precipitated silver oxide in an aqueous solution of aetylsalicylic acid hexamethylenetetramine enters with constant stirring. After filtering, the solution becomes in vacuo Brought dry. A lot of 10 parts of acetylsalicylic acid are added to 144 parts Hexamethylenetetramine dissolved in 500 parts of distilled water and put into this solution 8 parts of freshly precipitated silver oxide entered with constant stirring. After this Filtration, the solution is brought to dryness in vacuo.
