Description

Verfahren zur Abscheidung des Kaliumperchlorats aus solches enthaltenden Salzgemengen. Die Aufarbeitung großer Mengen Ammonsalpetersprengstöff, welche Kaliumperchlorat enthalten, macht die Trennung des als Pflanzengift bekannten Kaliumperchlorats von Ammonnitrat zwecks Verwendung zur . Düngung notwendig.- Es wurde nun gefunden, daß dies hier und in anderen Fällen, in welchen es sich um die Abtrennung des Kaliumperchlorats von anderen löslichen Salzen handelt, dadurch geschehen kann, daß das Gemenge mit der konzentrierten Lösung eines Kalisalzes ausgelaugt wird. Zweckmäßig nimmt man hierzu leicht lösliche Kalisalze, wie Chlorkalium oder Karnallit, mit deren konzentrierten Lösungen wohl der leicht lösliche Ammonsalpeter beim Digerieren auszulaugen ist, während das schwer lösliche Kaliumperchlorat darin völlig unlöslich ist.Process for separating the potassium perchlorate from such containing Salt mixes. The processing of large amounts of ammonium nitrate explosives, which are potassium perchlorate contains, makes the separation of potassium perchlorate, known as a plant poison, from Ammonium nitrate for use for. Fertilization necessary .-- It has now been found that this here and in other cases in which the separation of the potassium perchlorate is involved is of other soluble salts, it can happen that the mixture with the concentrated solution of a potassium salt is leached. Appropriately one takes for this purpose easily soluble potassium salts, such as potassium chloride or carnallite, with their concentrated Solutions probably the easily soluble ammonium nitrate is leached out during digestion, while the poorly soluble potassium perchlorate is completely insoluble in it.

Beispiel. Ein Gemenge von io,o kg Ammonsalpeter und 1,4 kg Kaliumperchlorat werden mit einer Lösung von 1o kg Karnallit in 15 1 Wasser unter Umrühren digeriert. Die Temperatur sinkt hierbei bis auf o ° und darunter, wodurch zugleich etwas Chlorkalium sich abscheidet. Läßt man nunmehr unter mehrfachem Rühren die Lösung sich erwärmen oder fördert dies durch Einleiten von Dampf bis zur Höhe von 13 bis 15', so löst sich das ausgeschiedene Chlorkalium wieder auf, und Kaliumperchlorat allein bleibt so gut wie quantitativ und frei von Magnesium- oder Ammoniumsalzen zurück.Example. A mixture of 10.0 kg of ammonium nitrate and 1.4 kg of potassium perchlorate are digested with a solution of 10 kg of carnallite in 15 l of water while stirring. The temperature drops to 0 ° and below, which at the same time creates some potassium chloride separates. The solution is now allowed to warm up while stirring several times or promotes this by introducing steam up to a height of 13 to 15 ', so solves the excreted potassium chloride is reassigned, and potassium perchlorate alone remains as good as quantitative and free of magnesium or ammonium salts.
