Form der   BromwaS8erstof'8iure.   



   Die mannigfache Verwendung der Bromwasserstoffsäure in der Heilkunde leidet an dem   Überstände,   dass die   Säure   in flüssiger Form verwendet werden muss ; sie lässt sich daher nur schwer dosieren, und die ätzenden Eigenschaften der Säure machen sich, besonders beim Aufbewahren der   Abfassungen,   sehr unangenehm bemerkbar. 



   Es wurde nun gefunden, dass diese   Übelstände wegfallen, wenn   man die Säure in das bisher nicht bekannte Betainsalz   überführt.   Es zeigte sich nämlich, dass das Betainbrombydrat ein leicht wasserlösliches Salz bildet. das einen sehr angenehmen   Fruchtsäuregeschmack besitzt   und in wässeriger Lösung weitgehend hydrolytisch gespalten ist. Das feste Salz ist auch in der 
 EMI1.1 
 Pastillen gepresst werden ; diese sind äusseist bequem in der Handhabung, lösen sich leicht in   Wasser une eben   die therapeutische Wirkung der Bromwasserstoffsäure. 



   Die Herstellung des   Betainbromhydratea   kann z. B. durch Neutralisieren von Betainbase mit Bromwasserstoffsäure und Eindampfen der   Lösung   erfolgen ; andererseits kann Betainbromhydrat auch durch doppelte Umsetzung von anderen   Betainsaltcn   mit Salzen der Brom-   wasseistofl'säure, also .   B. dmch Einwirken von Bariumbromid auf Betainsulfat, erhalten werden. 



   Das so gewonnene bisher unbekannte   Betainbromhydrat ist   ein farbloses, gut kristallsierendes, an der Luft   beständiges   Salz. In Wasser ist es sehr leicht löslich ; ein Teil des Salzes löst sich in Alkohol in der Hitze in 17 Teilen, bei gewöhnlicher Temperatur in 60 Teilen auf. Von Methylalkohol bedarf die Sutstanz in der Hitze 11 Teile und bei gewöhnlicher Temperatur 25 Teile zur Lösung. sie enthält   41% H Br.

  Process for the production of a particularly suitable for medicinal use
Form of the bromine sulfate.



   The multiple uses of hydrobromic acid in medicine suffers from the supernatant that the acid must be used in liquid form; it is therefore difficult to dose, and the caustic properties of the acid are very unpleasantly noticeable, especially when storing the compositions.



   It has now been found that these inconveniences are eliminated if the acid is converted into the previously unknown betaine salt. It was shown that the betaine bromide hydrate forms an easily water-soluble salt. which has a very pleasant fruit acid taste and is largely hydrolytically split in an aqueous solution. The solid salt is also in the
 EMI1.1
 Pastilles are pressed; These are extremely convenient to use, easily dissolve in water and have the therapeutic effect of hydrobromic acid.



   The production of Betainebromhydratea can, for. B. by neutralizing betaine base with hydrobromic acid and evaporating the solution; on the other hand, betaine bromohydrate can also be produced by double reaction of other betaine salts with salts of hydrobromic acid. B. can be obtained by the action of barium bromide on betaine sulfate.



   The previously unknown betaine bromide hydrate obtained in this way is a colorless, well crystallizing salt that is stable in the air. It is very easily soluble in water; One part of the salt dissolves in alcohol in 17 parts in the heat, in 60 parts in normal temperature. The substance requires 11 parts of methyl alcohol to dissolve in the heat and 25 parts at ordinary temperature. it contains 41% H Br.
