Description

Verfahren zur Herstellung von Ammoniak aus Cyaniden. Gegenstand der Erfindung ist ein Verfahren zur Herstellung von Ammoniak aus. Cyaniden unter Erhitzung in Gegenwart von Wasser, und die Erfindung findet besonders Anwendung, wenn das Cyanid durch die Absorption freien Stickstoffes bei Erhitzung in .einer Mischung von Alkalimetallen oder alkalischen Erdmetallen oder deren Verbindungen und Kohle hergestellt ist. Bei dieser letztgenannten Reaktion werden gewöhnlich, um die Reaktion zu beschleunigen, Metalle, wie z. B. Eisen oder Mangan usw., zugesetzt. Dieser Zusatz von Metallen kann jedoch in manchen Fällen große Nachteile und Gefahr für die Umgebung mit sich bringen.Process for the production of ammonia from cyanides. Subject of Invention is a process for the production of ammonia from. Cyanides under heating in the presence of water, and the invention finds particular application when that Cyanide through the absorption of free nitrogen when heated in a mixture of alkali metals or alkaline earth metals or their compounds and coal is made. In this latter reaction are usually to the reaction to accelerate metals, such as B. iron or manganese, etc., added. This addition However, metals can in some cases have great disadvantages and danger to the environment entail.

Wenn die Masse z. B. in heißem Zustande aus dem Reaktionsgefäß abgezogen wird und unmittelbar in ein Gefäß oder einen Autoklaven mit Wasser zur Herstellung von Ammoniak eingeführt werden soll, so bildet das in der Masse zurückbleibende Metall mit dem Wasser Wasserstoff in großen Mengen, und wenn die Masse sehr warm ist, z. B. 9oo ° C oder mehr, so kann auch der freie Kohlenstoff in der Masse mit Wasser reagieren und damit Wasserstoff bilden. Wenn nun Luft vorhanden ist, wird natürlicherweise Knallgas entstehen, und um dieser Gefahr vorzubeugen wird nach der vorliegenden Erfindung sowohl das Abzapfen der Masse aus dem Reaktionsgefäß als auch ihre Einführung in den Autoklaven unter Luftabschluß bewirkt. Um die Luft gänzlich auszuschließen wird nach der Erfindung ein Gas, welches keinen freien Sauerstoff enthält, über dem Wasser in den Autoklaven oder das Gefäß, worin die Ammoniakbildung vor sich geht, eingeführt.If the mass z. B. withdrawn from the reaction vessel in a hot state and immediately into a vessel or an autoclave with water for production of ammonia is to be introduced, it forms what remains in the mass Metal with the water hydrogen in large quantities, and when the mass is very warm is e.g. B. 900 ° C or more, so can the free carbon in the mass with React water and thus form hydrogen. If there is now air, it will oxyhydrogen gas is produced naturally, and this risk is being avoided of the present invention both the tapping of the mass from the reaction vessel as well as their introduction into the autoclave in the absence of air. To the air According to the invention, a gas which does not contain free oxygen can be completely excluded contains, above the water in the autoclave or the vessel in which the ammonia formation going on, introduced.
