Description

Herstellung eines zur Absorption von Stickstoff geeigneten Calciums Nach dem Verfahren der Patentschrift 494 2 12 läßt sich Calcium zur Absorption von Stickstoff dadurch besonders reaktionsfähig machen, daß man Alkalimetalle, besonders Natrium, in sehr geringer Menge und in äußerst feiner Verteilung auf der Oberfläche des Calciums niederschlägt. Da Natriummetall an sich ziemlich teuer ist und besonders die gleichmäßige, feine Verteilung geringer Mengen von Alkalimetallen auf der Oberfläche des Calciums gewisse experimentelle Schwierigkeiten bereitet, so tvurden Versuche unternommen, an Stelle der Alkalimetalle ihre billigeren und leichter zu handhabenden Verbindungen zu verwenden.Production of a calcium suitable for the absorption of nitrogen According to the method of patent specification 494 2 12, calcium can be used to absorb Make nitrogen particularly reactive by using alkali metals, especially Sodium, in very small amounts and in extremely fine distribution on the surface of calcium precipitates. Since sodium metal in itself is quite expensive and special the even, fine distribution of small amounts of alkali metals on the surface of calcium presents certain experimental difficulties, experiments were carried out undertaken to replace the alkali metals with their cheaper and easier-to-use ones Connections to use.

Es hat sich dabei gezeigt, daß an Stelle von Alkalimetallen, insbesondere von Natrium, deren Hydroxyde, also besonders Natriumhydroxyd, verwendet werden können. Es genügt, geringe Mengen von Alkalihydroxyd, z. B. Natriumhydroxyd, auf der Oberfläche kalter Calciumstücke oder Calciumspäne zu verteilen. So können diese beispielsweise durch feinste Zerstäubung der geschmolzenen wasserfreien Alkalihydroxyde selbst oder ihrer wässerigen Lösungen oder schließlich auch in pulverisierter Form auf die Calciumoberfläche gebracht werden. Das so vorbereitete Calcium absorbiert Stickstoff bei denselben Temperaturen und ebenso rasch wie Calcium, das nach dem im Hauptpatent beschriebenen Verfahren mit Alkalimetalldampf aktiviert wurde.It has been shown that instead of alkali metals, in particular of sodium, the hydroxides of which, especially sodium hydroxide, can be used. It is sufficient to use small amounts of alkali metal hydroxide, e.g. B. Sodium Hydroxide, on the surface to distribute cold pieces of calcium or calcium shavings. For example through the finest atomization of the melted anhydrous alkali hydroxides themselves or their aqueous solutions or finally in powdered form the calcium surface can be brought. The calcium prepared in this way absorbs nitrogen at the same temperatures and just as quickly as calcium, the one in the main patent described method was activated with alkali metal vapor.
