Description
<Desc/Clms Page number 1>
Verfahren zur Darstellung von Alkalimetallen.
EMI1.1
Reaktion geht in der oben erläuterten Weise nach der Gleichung :
EMI1.2
vor sich. Anstatt von dem fertigen Sulfid auszugehen, kann man auch in der Weise vor- gehen, dass man im Destilliergefäss das entsprechende Sulfat mit Kohle zu Sultid reduziert, dann das karbid einträgt und das Alkalimetall abdestilliert.
PATENT-ANSPRÜCHE : 1. Verfahren zur Darstellung von Alkalimetallen, dadurch gekennzeichnet, dass man Karbide der Erdalkalimetalle auf die Sulfide der Alkalimetalle bei Destillationstemperatur der letzteren einwirken lässt.
EMI1.3
**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

Process for the preparation of alkali metals.
EMI1.1
Reaction goes in the manner explained above according to the equation:
EMI1.2
in front of you. Instead of starting with the finished sulfide, you can also proceed in such a way that the corresponding sulfate is reduced to sulfide with charcoal in the still, then the carbide is introduced and the alkali metal is distilled off.
PATENT CLAIMS: 1. Process for the preparation of alkali metals, characterized in that carbides of the alkaline earth metals are allowed to act on the sulfides of the alkali metals at the distillation temperature of the latter.
EMI1.3
** WARNING ** End of DESC field may overlap beginning of CLMS **.
