Zusatz zum Patente 181991 vom 21. Juni 1905.Addendum to patent 181991 of June 21, 1905.

Patentiert im Deutschen Reiche vom 15. April 1906 ab. Längste Dauer: 20. Juni 1920.Patented in the German Empire on April 15, 1906. Longest duration: June 20, 1920.

Vorliegende Erfindung betrifft eine Verbesserung des Verfahrens zur Darstellung von Alumiumstickstoffverbindungen gemäß Patent 181991, nach welchem Aluminiumcarbid, erhitzt und der Einwirkung von Stickstoff ausgesetzt wird. Die Verbesserung besteht darin, daß der Stickstoff im Gemisch mit Salzsäuregas oder Schwefeldioxyd auf das Aluminiumcarbid zur Einwirkung gebracht wird, wodurch die Bildung der Stickstoffverbindungen wesentlich gefördert wird. Die Menge der dem Stickstoff zuzusetzenden Säuregase braucht nur sehr gering zu sein, um diese Wirkung zu erzielen. Ebenso kann die Zufuhr dieser Gase zum Stickstoff in beliebiger Weise erfolgen, so z. B. dadurch, daß man den Stickstoff, bevor man ihn mit dem Aluminiumcarbid in Reaktion bringt, durch Gefäße leitet (selbstverständlich unter Zurückhaltung eventuell mitgerissener Wasserdämpfe), in denen diese Gase sich entweder in mehr oder weniger konzentrierter wässeriger Lösung befinden, oder aus denen sie sich sonstwie entwickeln können.The present invention relates to an improvement in the method of display of aluminum nitrogen compounds according to patent 181991, according to which aluminum carbide, heated and exposed to nitrogen. The improvement is there in that the nitrogen, mixed with hydrochloric acid gas or sulfur dioxide, acts on the aluminum carbide , whereby the formation of nitrogen compounds is significantly promoted. The amount of nitrogen to be added Acid gases only need to be very small to achieve this effect. Likewise, the supply of these gases to nitrogen done in any way, such. B. by having the nitrogen before brings it into reaction with the aluminum carbide, passes it through vessels (of course with retention of possibly entrained water vapors), in which these gases are either more or less concentrated watery solution, or from which they can otherwise develop.
