Description

Verfahren zur Gewinnung salpetersauren Strontiums. In dem Hauptpatent 3(9a.051 wurde ein Verfahren zur teilweisen oder vollständigen Trennung von löslichen Strontium- und Calciumverbindungen beschrieben, nach dein man auf wässerige Lösungen dieser Verbin-(lungen Strontiumsilikat oder strontiumsilikatha.ltige Stoffe einwirken läßt. Als strontiumsilikathaltige Stoffe kommen z. B. die schlammförmigen Rückstände in Betracht, welche bei der Aufschließung von Coelestin finit Kohle nach Auslaugung des gebildeten Schwefelstrontiums verbleiben.Process for obtaining nitric acid strontium. In the main patent 3 (9a.051 established a process for the partial or complete separation of soluble Strontium and calcium compounds are described, according to which you apply to aqueous solutions These compounds are affected by strontium silicate or strontium silicate-containing substances leaves. As strontium silicate substances come z. B. the muddy residues into consideration, which in the digestion of Celestine finite coal after leaching of the sulfur strontium formed remain.

rs wurde nun gefunden, daß man dieses -'er fahren erfolgreich verwenden kann, uni natürlich vorkommenden Strontianit auf salpetersaures Strontium zu verarbeiten, welches ii. a. zur Erzeugung des Rotfeuers von Leuchtraketen und Feuerwerken in großem 'Maßstabe lyenutzt wird. Zu den genannten Zwecken löst man natürlich vorkominenden Strontianit, welcher z. B. aus etwa 85 Prozent kohlensaurem Strontium und 1.5 Prozent kohlensaurem Calcium besteht, in Salpetersäure. Auf diese Weise erhält man eine .Mischung von salpetersaurem Strontiuin und salpetersaurem Calcium.rs has now been found that you can use this -'er drive successfully able to process uni naturally occurring strontianite on nitric acid strontium, which ii. a. for generating the red fire of flares and fireworks in is used on a large scale. For the purposes mentioned, one naturally resolves those that occur Strontianite, which z. B. from about 85 percent carbonate strontium and 1.5 percent Carbonate consists of calcium in nitric acid. This is how you get one Mixture of strontium nitric acid and calcium nitric acid.

Indem man diese Mischung entsprechend dem Verfahren des Hauptpatents mit Strontiumsilikaten oder strontiumsilikathaltigen Rückständen behandelt, erhält man technisch reines salpetersaures Strontium, während das Ca@lcitnn unlöslich wird.By making this mixture according to the procedure of the main patent treated with strontium silicate or residues containing strontium silicate technically pure nitric acid strontium, while the Ca @ lcitnn becomes insoluble.

B ei spiel.Example.

Aus 3o kg Strontianit, der 84,6prozentiges kohlensaures Strontium und z5,zprozentiges kohlensaures Calcium enthielt, wurde eine neutrale Nitratlösung hergestellt, indem inan auf das fein gepulverte :Mineral 36 1 einer technischen Salpetersäure von 37° Be, die mehrere Prozent Schwefelsäure enthielt, und 5o 1 Wasser einwirken ließ. Diese Nitratlösung wurde sodann mit 7o kg Strontianrückstand, wie man diesen bei der Darstellung von Schwefelstrontium aus Coelestin und Kohle und rachherigem Auslaugen mit Wasser als unlösliches schlammartiges Abfallprodukt erhält, unter Zusatz von Wasser r bis 2 Stunden im Autoklaven bei 5 bis 6 Atm. unter Rühren erhitzt und dann das Gemisch al:genutscht und ausge"vaschen. Es wurden erhalten .42 kg salpetersaures Stronti.um von technischer Reinheit, denn es enthielt auf ioo g Strontiumnitrat nur 0,r4 g Calciumnitrat,während der ursprünglich angewandte Strontianit auf ioo Teile Strontiumnitrat 2o,4 Teile Calciumnitrat ohne den Prozeß der Reinigung erbeben hätte.From 30 kg of strontianite, the 84.6 percent carbonate of strontium and z5, containing 10 percent calcium carbonate, became a neutral nitrate solution produced by inan on the finely powdered: Mineral 36 1 of a technical Nitric acid of 37 ° Be, which contained several percent sulfuric acid, and 50 liters of water let act. This nitrate solution was then mixed with 70 kg of strontian residue, such as one this in the representation of sulfur strontium from Celestine and coal and leaching with water as an insoluble sludge-like waste product, with the addition of water for up to 2 hours in an autoclave at 5 to 6 atm. while stirring heated and then the mixture al: sucked and washed out. It was obtained .42 kg of nitric acid strontium of technical purity because it contained 100 g strontium nitrate only 0.4 g calcium nitrate, during the originally applied Strontianite to 100 parts of strontium nitrate 2o.4 parts calcium nitrate would have trembled without the process of purification.
