Description

Anwendung des Verfahrens des Hauptpatentes 500 692 auf andere metallcarbonyle als Eisencarbonyl oder auf beliebige Carbonylgemische Das Patent 5oo 692 betrifft ein Verfahren zur Herstellung von reinem Eisen voll ausgezeichneten Eigenschaften durch thermische Zersetzung Ivon Eisencarbonyl, wobei man dieses in einen erhitzten Hohlraum derart einführt, daß es eine längere Strecke im Gasraum durchlaufen muß, ehe es mit der Wandung in Berührung kommt, so daß es sich in der Hauptsache irre freien Rauire zersetzt.Application of the process of main patent 500 692 to other metal carbonyls as iron carbonyl or any carbonyl mixture. Patent 5oo 692 relates a process for producing pure iron full of excellent properties by thermal decomposition of iron carbonyl, which is heated in a Introduces cavity in such a way that it has to travel a longer distance in the gas space, before it comes into contact with the wall, so that it is essentially wrong free rauire decomposes.

Es hat sich nun gezeigt, daß man dieses Verfahren auch auf andere Metallcarbonvle als Eisencarbonyl oder Gemische solcher gegebenenfalls mit Eisencarbonyl anwenden und auf diese Weise die betreffenden 1letalle in feinster Verteilung und reinster Beschaffenheit ähnlich wie das Eisen erhalten kann.It has now been shown that this procedure can also be applied to others Metallcarbonvle as iron carbonyl or mixtures of such optionally with iron carbonyl apply and in this way the relevant 1letalle in the finest distribution and purest quality similar to what iron can get.

Das Metallcarbonyl bzw. Carbonylbenisch wird am zweckmäßigsten dampfförmig, unverdünnt oder mit indifferenten Gasen oder Dämpfen vermischt in den Ofenhohlraum eingeführt. Ist das Carbonyl fest, wie z. B. das Kobaltcarbonyl, und besitzt es nur geringen Dampfdruck, so kann man auch so arbeiten, daß man es unter Kohlenoxv.ddruck schmilzt und in den erhitzten Raum hinein zerstäubt. Oder man löst das Carbonvl bzw. das Gemisch in einem geeigneten Lösungsmittel, z. h. Benzin-, und spritzt diese Lösung in den Zersetzungsraum ein. Hierbei fällt (las durch Zersetzung des Carbomvls -iin freien Räum gewonnene Metallpulver zu Boden, während das Lösungsmittel dampfför-@-ml-g # mit dem Kohlenoxyd entweicht und durch Kühlung oder andere -Maßnahmen zurückgewonnen werden kann. Als Lösungsmittel für .die festen Carbomvle können auch flüssige Carbonyle dienen.The metal carbonyl or carbonylbenisch is most conveniently in vapor form, undiluted or mixed with inert gases or vapors into the furnace cavity introduced. If the carbonyl is solid, e.g. B. cobalt carbonyl, and has it only low vapor pressure, so one can also work in such a way that it is carried out under carbon dioxide pressure melts and atomizes into the heated room. Or you can solve the Carbonvl or the mixture in a suitable solvent, e.g. H. Gasoline, and splashes this Solution into the decomposition room. During this process (read by the decomposition of the carbomol -i in free space obtained metal powder to the ground, while the solvent steam - @ - ml-g # escapes with the carbon dioxide and is recovered by cooling or other measures can be. Liquid carbonyls can also be used as solvents for the solid carbomide to serve.

Die Zersetzung des Carbonyls bzw. CarbonvIgemisches kann bei gewöhnlichem, vermindertem oder erhöhtem Druck ausgeführt werden; die hierfür günstigste Temperatur ist abhängig von der Art der betreffenden Carbonyle, des etwa beigemischten Gases und deni angewandten Druck; z. B. liefert Kobaltcarbonyldampf, der mit Köhlenox@#d verdünnt und in einen auf - r5o° erhitzten Hohlraum geleitet wird, praktisch reines Kobalt von außerordentlich feiner Verteilung. Im allgemeinen erhält man bei niedrigeren Temperaturen ein schweres, sehr feines Metallpulver, bei höheren Temperaturen dagegen leichte, schwammige Metallflocken, die besonders für katalytische Zwecke sehr -eignet sind. Außer Kobaltcarbonyl kommen beispielsweise \'ickelcarbonyl, Molvbdäncarbonv l usw. in Betracht.The decomposition of the carbonyl or carbon mixture can be carried out under normal, reduced or increased pressure; the most favorable temperature for this depends on the type of carbonyls in question, the gas that may be added and the pressure used; z. For example, cobalt carbonyl vapor, which is diluted with Köhlenox @ # d and passed into a cavity heated to - r5o °, provides practically pure cobalt with an extraordinarily fine distribution. In general, a heavy, very fine metal powder is obtained at lower temperatures, whereas light, spongy metal flakes, which are particularly suitable for catalytic purposes, are obtained at higher temperatures. In addition to cobalt carbonyl, nickel carbonyl, molybdenum carbonyl, etc., are also suitable.
