Description
Verfahren zur Gewinnung von Natriumsulfat. \acli dein Verfahren des Patents 4o5922 `#..,: innt inan Sulfate (her filen Alkalien aus .1uiuionsulfat und wasserlöslichen Salzen der ü#.en Alkalien, indem inan 7.B. in eine 'Mischung der gesättigten Lösungen der betref-@V,iden Ausgangsstoflfc gasförmiges Ainmonialc einleitet, wodurch die Allcalisulfate zur Abscheidung gelangen, während das entsprechende Ainnionsalz in Lösung bleibt.Process for the production of sodium sulphate. \ acli the process of the patent 4o5922 `# ..,: inan sulfates (from filen alkalis from .1uiuionsulfat and water-soluble salts of the above alkalis, by inan 7.B. in a 'mixture of the saturated solutions of the concerned @ V, iden the starting material fc introduces gaseous ammonia, whereby the allcalisulphates reach the deposition, while the corresponding ammonium salt remains in solution.
Es wurde nun gefunden, daß man das Verf<<hren vorteilhaft in der Weise durchführen kann, claß nian die Abscheidung des \ atriumsulfates mit Aninioniak bei der Umsetzung von Ainmonsulfat in einer an Chlorammonium gesättigten Lösung vornimmt. Bekanntlich ist Chlorammonium in einer starken Ammoniaklösung erheblich löslich, so daß das bei der doppelten Umsetzung entstehende Chloraninion in der amnioniakalischen Flüssigkeit in dein 'Maße, tvie es entsteht, in Lösung geht.It has now been found that the procedure is advantageous in who can carry out the separation of the atrium sulphate with anionic acid in the conversion of ammonium sulphate in a solution saturated with chlorammonium undertakes. As is known, chlorammonium is significant in a strong ammonia solution soluble, so that the chlorine anion formed in the double reaction in the Amniotic fluid dissolves in your measure as it arises.
ach der Abtrennung des abgeschiedenen Sulfates von der ammoniakalischen Flüssigkeit entfernt nian aus dieser das Ammoniak, wobei das hei der doppelten Umsetzung entstandene Chlorammonium in fast theoretischer Ausbeute ausfällt, d. h. man gewinnt nach dieser Arbeitsweise sowohl das Natriumsulfat wie das Chlorammonium in festem Zustande.after the separation of the separated sulphate from the ammoniacal one Liquid nian removes the ammonia from this, which means the double conversion resulting chlorammonium precipitates in almost theoretical yield, d. H. one wins after this procedure both the sodium sulfate and the chlorammonium in solid form Conditions.
Ausführungsbeispiel: In i 1 einer an Kochsalz und Chlorammonitun gesättigten Lösung trägt man 132 g Ammonsulfat und i i7 g Kochsalz ein. Darauf leitet man zweckmäßig bei einer Temperatur von etwa ro° Ammoniak bis zur Sättigung ein, trennt von dein ausgeschiedenen Natriumsulfat und bringt -durch Austreiben des Ammoniaks aus der Mutterlauge das Chlorainnionium zur Abscheidung.Exemplary embodiment: In i 1, one saturated in table salt and chlorammonite Solution are introduced into 132 g of ammonium sulphate and 17 g of sodium chloride. One leads to it appropriately at a temperature of about ro ° ammonia to saturation, separates from your precipitated sodium sulfate and brings -by expelling the ammonia from the Mother liquor the chlorinenionium for separation.
