Description

  

  Verfahren zur Darstellung von     Diäthanolamin-Calciumbromid.       Das Hauptpatent betrifft ein Verfahren  zur Darstellung von     Triäthanolamin-Calcium-          bromid.     



  Gegenstand des vorliegenden Patentes ist  ein Verfahren zur Darstellung des     Diäthanol-          amin-Calciumbromids.    Das Verfahren ist da  durch gekennzeichnet, dass man     Calciumbro-          mid    auf     Diäthanolamin    einwirken lässt. Die  Umsetzung wird zweckmässig in Gegenwart  eines Löse- oder     Verdünnemittels,    z. B. Al  kohol, vorgenommen.  



  Das so erhältliche, bisher noch nicht be  kannte     Diäthanolamin-Calciumbromid    ist ein  farbloses, hochschmelzendes, kristallines, an  der Luft beständiges Produkt, das sich in  Wasser mit alkalischer Reaktion löst. Es  kann für pharmazeutische Zwecke Verwen  dung finden.  



       Beispiel:     20 Gewichtsteile     Calciumbromid    (wasser  frei) werden in 65 Gewichtsteilen Alkohol  gelöst, filtriert und 20 Gewichtsteile     Diätha-          nolamin    zugegeben und mit Eiswasser ge  kühlt. Die auskristallisierte Verbindung  wird mit wenig Alkohol     gewaschen    und ge-    trocknet. Beim Einengen der     Mutterlauge     erhält man weitere Mengen des Salzes. Das  so erhaltene     Diäthanolamin-Calciumbromid     hat die     oben    angegebenen Eigenschaften.



  Process for the preparation of diethanolamine calcium bromide. The main patent relates to a process for the preparation of triethanolamine calcium bromide.



  The subject of the present patent is a process for the preparation of diethanolamine calcium bromide. The process is characterized in that calcium bromide is allowed to act on diethanolamine. The reaction is conveniently carried out in the presence of a solvent or diluent, e.g. B. Al alcohol.



  The previously unknown diethanolamine calcium bromide is a colorless, high-melting, crystalline product which is stable in air and which dissolves in water with an alkaline reaction. It can be used for pharmaceutical purposes.



       Example: 20 parts by weight of calcium bromide (anhydrous) are dissolved in 65 parts by weight of alcohol, filtered, and 20 parts by weight of diethanolamine are added and cooled with ice water. The compound which has crystallized out is washed with a little alcohol and dried. When the mother liquor is concentrated, additional amounts of the salt are obtained. The diethanolamine calcium bromide thus obtained has the properties given above.
