Description
Herstellung von Alkalinitraten durch Umsetzung von Ammonnitrat mit Alkaiibicarbonaten Es ist bekannt, daß man Ammoniumnitrat wegen seiner hygroskopischen und explosiblen Eigenschaften nicht unmittelbar als Düngemittel verwenden kann. Es sind daher schon die verschiedensten Vorschläge gemacht, um wenigstens mittelbar dieses Salz für den vorgenannten Zweck dienlich zu machen, indem es mit anderen Salzen umgesetzt wird.Production of alkali nitrates by reacting ammonium nitrate with Alkaiibicarbonaten It is known that one uses ammonium nitrate because of its hygroscopic and explosive properties can not use directly as fertilizer. The most varied proposals have therefore already been made, at least indirectly To make this salt useful for the aforementioned purpose by sharing it with others Salts is implemented.
So ist es bekannt, eine konzentrierte Lösung von Ammoniumnitrat oder eine wasserhaltige Schmelze mit anorganischen Salzen zu vermischen unter Gewinnung von Mischdüngern. Auch ist es bekannt, aus Ammoniumnitrat mit verschiedenen anderen Salzen Alkalinitrat herzustellen. Bei diesen bekannten Verfahren wird aber stets in Lösung gearbeitet.So it is known to be a concentrated solution of ammonium nitrate or to mix a water-containing melt with inorganic salts to obtain of mixed fertilizers. It is also known from ammonium nitrate with various others Salts to produce alkali nitrate. In these known methods, however, is always worked in solution.
Es ist auch schon vorgeschlagen worden, Natronsalpeter aus Ammoniumnitrat und Kochsalz herzustellen, bei dem in wässeriger Lösung Natriumbicarbonat als Zwischenkörper Verwendung findet, wobei eine Erwärmung auf höchstens 75 ° C stattfindet.It has also been suggested to use sodium nitrate from ammonium nitrate and to produce common salt, in which sodium bicarbonate as an intermediate body in aqueous solution Is used, with heating to a maximum of 75 ° C takes place.
Im Gegensatz zu diesen bekannten Verfahren, die alle in Lösung arbeiten, ist der Gegenstand der Erfindung die quantitative Umsetzung von Ammoniumnitrat mit Alkalibicarbonat in trokkenem oder schwach feuchtem Zustande in Natron- bzw. Kalisalpeter unter unmittelbarer Gewinnung eines trockenen Salzes, wobei das gebildete Ammoniumbicarbonat im gleichen Arbeitsgang vollständig verflüchtigt wird. Der Vorgang verläuft nach folgender Gleichung: NH,N03 + NaHC03 = NaN03+NH4HC03. Die beiden Salze werden in trockenem oder leicht feuchtem Zustande unter Erwärmen auf zoo bis 130 ' C zur Reaktion gebracht, wobei sich das gebildete Ammonbicarbonat verflüchtigt. Die Reaktion verläuft rasch und quantitativ, da infolge der fortlaufenden Entfernung der einen Komponente aus der Reaktionsphase die Bedingungen für die Bildung von Alkalinitrat außerordentlich begünstigt werden. Ausführungsbeispiel Eine Mischung molekularer Mengen von trockenem oder schwach feuchtem, jedoch festem Ammonnitrat und Natriumbicarbonat wird in einem Gefäß auf etwa zoo bis 13o ° C erhitzt, wobei das Ammoniumnitrat vollständig zu reinem Natriumnitrat umgesetzt wird, das in der anfallenden Form unmittelbar, z. B. als Düngemittel, Verwendung finden kann, denn die zweite Reaktionskomponente, nämlich das Ammoniumbicarbonat, verflüchtigt sich vollständig und kann z. B. in einer Vorlage zu beliebiger Verwendung aufgefangen werden.In contrast to these well-known methods, which all work in solution, the subject of the invention is the quantitative conversion of ammonium nitrate with Alkali bicarbonate in a dry or slightly moist state in sodium or potassium nitrate with immediate production of a dry salt, the ammonium bicarbonate formed is completely volatilized in the same operation. The process continues after following equation: NH, N03 + NaHC03 = NaN03 + NH4HC03. The two salts are in dry or slightly moist condition with warming to zoo to 130 ° C for reaction brought, with the formed ammonium bicarbonate volatilized. The reaction proceeds Quickly and quantitatively, as a result of the continuous removal of one component from the reaction phase the conditions for the formation of alkali nitrate are extraordinary be favored. Embodiment A mixture of molecular quantities of dry or slightly moist, but solid ammonium nitrate and sodium bicarbonate are combined in one Vessel heated to about zoo to 130 ° C, with the ammonium nitrate completely closed pure sodium nitrate is implemented, which in the resulting form immediately, z. B. as fertilizer, can be used, because the second reaction component, namely the ammonium bicarbonate, volatilized completely and can, for. Am a template for any use.
Zur Förderung der Reaktion zwischen dem Ammoniumnitrat und dem Alkalibicarbonat kann man durch das Gefäß auch noch Luft oder Dampf hindurchleitenTo promote the reaction between the ammonium nitrate and the alkali bicarbonate can air or steam can also be passed through the vessel
