Verfahren zur Herstellung reiner schwefelsaurer Kalimagnesia mittelst Carnallits und Kieserits in concentrirten Lösungen bei gewöhnlicher Temperatur.Process for the production of pure potassium magnesia sulfuric acid by means of carnallite and kieserite in concentrated solutions at ordinary temperature.
Patentirt im Deutschen Reiche vom 7. Juli 1878 ab.Patented in the German Empire on July 7, 1878.
Zu einer Bittersalzlauge von 1,198 spec. Gew. und von Lufttemperatur wird so lange künstlicher Carnallit gesetzt, bis die darüber stehende klare Lauge ein spec. Gew. von 1,270 zeigt. Die Zersetzung geschieht unter Umrühren in irgend einem Gefäfse, welches zu diesem Zwecke mit einem leichten Rührwerke versehen ist. Nach geschehener Zersetzung läfst man den Niederschlag von krystallisirter schwefelsaurer Kalimagnesia (K2 -S1C4 ■+- Mg SOt + 6 aq) sich absetzen und schwingt ihn in einer Schleudermaschine zur Trocknifs, nachdem zuvor die darüber stehende Lauge entfernt war.To an Epsom salt liquor of 1.198 spec. Artificial carnallite is added by weight and air temperature until the clear lye above it has a spec. Shows weight of 1.270. The decomposition takes place with stirring in any vessel which is provided with a light stirrer for this purpose. After the decomposition has taken place, the precipitate of crystallized sulphate of potassium magnesia (K 2 -S 1 C 4 + - Mg SO t + 6 aq) is allowed to settle and it is swung to dryness in a centrifugal machine, after the caustic above has been removed.
Dies Verfahren ist insofern neu und eigenthümlich, als bisher einerseits die Bildung von reiner krystallisirter schwefelsaurer Kalimagnesia aus Chlorkalium und schwefelsaurer Magnesia, welche Körper im geeigneten stöchiometrischen Verhältnifs im Kainit vorhanden sind, durch Kochen geschah, andererseits sich aus kochender Auflösung von Bittersalzlauge und Carnallit stets Chlorkalium und dann erst zum geringeren Theile schwefelsaure Kalimagnesia ausscheidet.This procedure is new and peculiar in that, on the one hand, the formation of pure crystallized sulphate of potassium magnesia from chlorine potassium and sulphate of magnesia, which bodies are present in the kainite in the appropriate stoichiometric ratio Cooking happened, on the other hand, from the boiling dissolution of Epsom salts and carnallite always potassium chloride and then only to a lesser extent potassium magnesia sulfuric acid precipitates.
