KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die vorliegende Erfindung bezieht sich auf die Gewinnung eines Ammoniumnitrat-Natriumnitrat-Gemisches, bei welchem der Procentgehalt an Ammoniumnitrat beliebig hoch sein kann. Ein Gemisch derartiger Salze eignet sich unter Voraussetzung einer billigen Herstellungsweise vortheilhaft zur Erzeugung von Sprengstoffen.The present invention relates to the production of an ammonium nitrate-sodium nitrate mixture, at which the percentage of ammonium nitrate can be arbitrarily high. A mixture of such salts is advantageously suitable for production provided that it is inexpensive to manufacture of explosives.
Das Verfahren zur Herstellung des vorstehenden Salzgemisches ist das folgende:The procedure for making the above salt mixture is as follows:
Man löst Natriumnitrat und Ammoniumsulfat in Wasser auf und läfst die Lösung auskrystallisiren, wodurch ein Theil des infolge der doppelten, aber unvollständigen Umsetzung entstandenen Natriumsulfats abgeschieden wird. Die Krystalle werden nun von der die Nitrate und Sulfate von Ammoniak und Natron enthaltenden Mutterlauge getrennt, und wird der letzteren nunmehr ein solches Salz hinzugefügt, zweckmäisig ein salpetersaures Salz, dessen Base ein unlösliches bezw. ein schwerlösliches Sulfat bildet. Statt des Salzes kann auch die Base selbst verwendet werden. Es schlägt sich ein Sulfat nieder und die klare Lösung besteht aus mehr oder weniger reinem Ammonium- und Natriumnitrat.Dissolve sodium nitrate and ammonium sulfate in water and let the solution crystallize out, thereby part of the result of the double but incomplete conversion resulting sodium sulfate is deposited. The crystals are now made up of the nitrates and sulphates of ammonia and mother liquor containing soda separated, and the latter is now a such a salt is added, expediently a nitric acid salt, the base of which is an insoluble one respectively forms a sparingly soluble sulfate. Instead of the salt, the base itself can also be used will. A sulphate precipitates and the clear solution consists of more or less pure ammonium and Sodium nitrate.
Man trennt den Niederschlag von der klaren Lösung und gewinnt die in der Lösung enthaltenen Salze durch Verdampfen des Wassers oder durch Auskrystallisirenlassen.The precipitate is separated from the clear solution and those contained in the solution are recovered Salts by evaporation of the water or by allowing it to crystallize out.
Einige der Salze oder Oxyde, welche als un- oder schwerlösliche Sulfate abgeschieden werden, sind z. B. Bariumnitrate Calciumnitrat, Calciumhydrat, Calciumoxyd u. s. w. Wird ein Oxyd verwendet, so entsteht zufolge der Umsetzung zwischen dem Oxyd und dem Ammoniumsulfat neben dem Niederschlag von schwefelsaurem Salz freies Ammoniak, welches beim Abdampfen der Mutterlauge verdampft. Some of the salts or oxides which are deposited as insoluble or sparingly soluble sulfates are z. B. barium nitrates calcium nitrate, calcium hydrate, calcium oxide and so on. If an oxide is used, the reaction between the oxide and the Ammonium sulfate in addition to the precipitate of sulfuric acid salt free ammonia, which evaporated on evaporation of the mother liquor.
Bei der praktischen Durchführung des vorliegenden Verfahrens verfährt man in folgender Weise:The following procedure is used in practicing the present process Way:
Man löst etwa äquivalente Mengen von käuflichem Natriumnitrat und Ammoniumsulfat in Wasser und rührt die Mischung gut durch. Die in diesen Salzen enthaltenen Verunreinigungen setzen sich zu Boden, und die klare, oben schwimmende Lösung wird durch Abkühlen zur !Crystallisation gebracht. Je verdünnter die Lösung war, um so reiner sind die entstehenden Krystalle von Glaubersalz, und um so geringer ist infolge dessen der Verlust an den kostbaren salpetersauren Salzen.Approximately equivalent amounts of commercially available sodium nitrate and ammonium sulfate are dissolved in Water and stir the mixture well. The impurities contained in these salts sit on the bottom, and the clear, floating solution on top is cooled down brought to! crystallization. The more dilute the solution, the purer it is the resulting crystals of Glauber's salt, and the less is the loss as a result the precious nitric acid salts.
Die von der klaren Mutterlauge befreiten Krystalle sind ein Nebenproduct und können zu irgend welchen Zwecken Anwendung finden. The crystals freed from the clear mother liquor are a by-product and can can be used for any purpose.
Man fügt nun der Mutterlauge eine Lösung eines Salzes hinzu, dessen Base (z. B. Calciumnitrat) Schwefelsäure niederschlägt. Am zweckmäfsigsten verwendet man von dem Salz eine den in der Lösung befindlichen Sulfaten äquivalente Menge; man kann aber auch eine geringere Menge als der niederzuschla-A solution of a salt is now added to the mother liquor, the base of which (e.g. calcium nitrate) Sulfuric acid precipitates. Most appropriately one uses of that Salt an amount equivalent to the sulfates in the solution; but you can also a smaller amount than the
genden Schwefelsäuremenge entspricht, in Anwendung bringen. Man läfst den Niederschlag sich absetzen und verdampft die überstehende klare Flüssigkeit bis zur Trockne.corresponding to the amount of sulfuric acid. You let the precipitate settle and evaporate the supernatant clear liquid to dryness.
Das niedergeschlagene schwefelsaure Salz bildet ebenfalls ein zu beliebigen Zwecken verwerthbares Nebenproduct.The precipitated sulfuric acid salt also forms something that can be used for any purpose Byproduct.
Der aus einem Gemenge von Natrium- und Ammoniumnitrat bestehende Salzrückstand wird getrocknet und pulverisirt, worauf er zur Weiterverarbeitung brauchbar ist.The salt residue made up of a mixture of sodium and ammonium nitrate is dried and pulverized, whereupon it can be used for further processing.
Anstatt das Wasser zu verdampfen, kann man auch die Mutterlauge auskrystallisiren lassen und erhält so, je nachdem ein salpetersaures Salz oder ein Oxyd zum Niederschlagen der Schwefelsäure verwendet wurde, ein Gemenge von mehr oder weniger hohem Procentgehalt an Ammoniumnitrat.Instead of evaporating the water, the mother liquor can also be crystallized out and thus receives, depending on the case, a nitric acid salt or an oxide to precipitate the sulfuric acid was used, a mixture of more or less high percentage of ammonium nitrate.
