Description
verfahren zur Darstellung einer organischen Wismutverbindung. Gegenstand des vorliegenden Patentes ist ein Verfahren zur Darstellung einer organi schen Wismutverbindung, welches dadurch gekennzeichnet ist, dass man 1 Hol eines Alkalisalzes der Camphenilansäure und 2 Mol Alkali mit 1 WIol eines anorganischen Wis- mutsalzes umsetzt.
Die so erhaltene neue Verbindung ist in Ölen löslich. Sie soll als Arzneimittel Ver wendung finden. <I>Beispiel:</I> Eine Lösung von 16,8 g Camphenilan- säure mit 4 g Ätznatron und 150 cm' Was ser wird unter Rühren gleichzeitig versetzt mit einer Lösung von 48;5 g kristallisiertem Wismutnitrat in 150 cm' Glyzerin und 300 cm' Wasser und zweitens mit einer Lösung von 8 g Ätznatron in 100 cm0 Wasser derart, dass die Flüssigkeit stets lackmusalkalisch bleibt.
Der entstandene weisse Niederschlag wird abgesaugt, mit Wasser gewaschen und dann in Benzol gelöst. Aus der getrockneten filtrierten Benzollösung wird durch Eindamp fen das camphenilansaure Wismutoxyd der Formel C10H1r02 # -Bi0 mit einem Wismut- gehalt von 53;3 % (Theorie 53,3 1o) erhalten, das sich in Ö1 löst.
process for the preparation of an organic bismuth compound. The subject of the present patent is a process for the preparation of an organic bismuth compound, which is characterized in that 1 mol of an alkali salt of camphenilanic acid and 2 mol of alkali are reacted with 1 vol of an inorganic bismuth salt.
The new compound thus obtained is soluble in oils. It should be used as a medicinal product. <I> Example: </I> A solution of 16.8 g of camphenilanic acid with 4 g of caustic soda and 150 cm of water is simultaneously mixed with a solution of 48; 5 g of crystallized bismuth nitrate in 150 cm of glycerine and while stirring 300 cm 'of water and secondly with a solution of 8 g of caustic soda in 100 cm0 of water in such a way that the liquid always remains litmus-alkaline.
The resulting white precipitate is filtered off with suction, washed with water and then dissolved in benzene. The camphenilanoic acid bismuth oxide of the formula C10H1r02 # -Bi0 with a bismuth content of 53.3% (theory 53.3 10) is obtained from the dried, filtered benzene solution by evaporation, which dissolves in oil.
