Zusatz zum Patente 215007 vom 22. Juli 1908.*)Addendum to patent 215007 of July 22, 1908. *)
Patentiert im Deutschen Reiche vom 29.JuIi 1908 ab. Längste Dauer: 21. Juli 1923.Patented in the German Empire on July 29, 1908. Longest duration: July 21, 1923.
Bei dem Verfahren des Hauptpatentes und des ersten Zusatzpatentes werden das Calcium- und das Magnesiumsalz der Dibrombehensäure gewonnen, die im Gegensatz zu dem Barium- und dem Bleisalze geruchlose, geschmacklose und haltbare Brompräparate von erheblichem therapeutischen Wert sind.In the process of the main patent and the first additional patent, the calcium and the magnesium salt of dibromomehenic acid, which in contrast to the barium and the lead salt odorless, tasteless and durable bromine preparations of considerable are of therapeutic value.
Es wurde nun gefunden, daß die gleichen wertvollen Eigenschaften auch das bisher unbekannte Strontiumsalz der Dibrombehensäure aufweist. Die Darstellung dieses Salzes kann in ganz analoger Weise erfolgen, wie bei dem Verfahren der Patente 215007 und 215008 die Darstellung von Calcium- und Magnesiumsalz bewirkt wird.It has now been found that the same valuable properties also have the previously unknown Has strontium salt of dibromomehenic acid. The representation of this salt can be done in a completely analogous manner to that Procedure of patents 215007 and 215008 the Representation of calcium and magnesium salts is effected.
Dibrombehensäure wird in der erforderlichenDibromomehenic acid is required in the
Menge verdünnter Kalilauge (etwa 1Z40 normal) gelöst und die Flüssigkeit unter starkem RührenDissolve the amount of dilute potassium hydroxide solution (approx. 1 Z 40 normal) and stir the liquid vigorously
Früheres Zusatzpatent 215008.Former additional patent 215008.
mit der berechneten Menge einer verdünnten Lösung von Chlorstrontium versetzt. Das Strontiumsalz scheidet sich als weißer dicker Niederschlag ab, der scharf abgesaugt und mit Alkohol gewaschen wird. Dann verreibt man ihn mit kaltem Wasser, saugt wieder ab und wäscht mit Wasser bis zum Verschwinden der Chlorreaktion. Das Salz wird dann nochmals mit Alkohol gewaschen und im Vakuum getrocknet. Es bildet ein weißes, geschmackloses, haltbares, in Wasser und in Alkohol fast unlösliches Pulver.mixed with the calculated amount of a dilute solution of chlorstrontium. That Strontium salt separates out as a thick white precipitate, which is sucked off sharply and with Alcohol is washed. Then rub it in with cold water, vacuum and again washes with water until the chlorine reaction disappears. The salt is then again washed with alcohol and dried in vacuo. It forms a white, tasteless, durable powder, almost insoluble in water and alcohol.
