Description
Verfahren zur Gewinnung von Sulfaten der Alkalien. Es ist bekannt, daß die Sulfate der fixen Alkalien in Ammoniakwasser schwer löslich sind und daß man sie aus ihren Lösungen c furch Ammoniak zur Abscheidung bringen kann (vgl. z. B. G m e 1 i n - K r a u t, 7 . Auflage, Bd. II, i, S. 53).Process for obtaining sulphates of alkalis. It is known, that the sulfates of the fixed alkalis are sparingly soluble in ammonia water and that they can be separated from their solutions by ammonia (cf. B. G m e 1 i n - K r a u t, 7. Edition, Vol. II, i, p. 53).
Es wurde nun gefunden, daß man die genannten Sulfate auch aus solchen Lösungen durch Ammoniak in' fester Form abscheiden kann, in denen diese Sulfate sich aus Animonsulfat und anderen Verbindungen der fixen Alkalien durch doppelte Umsetzung zu bilden vermögen. Es ist zwar bekannt (s. z. B. G ni e 1 i n - IL r a tt t , j. Auflage, Bd. Il, i, S.48 unten und S. 322), daß man durch dop= Kelte Umsetzung von Amnionsulfat mit Kochsalz oder Natriumnitrat \atriunisulfat in der flitze aussoggen kann. Von diesem bekannten Verfahren unterscheidet sich jedoch das der vorliegenden Anmeldung dadurch, daß bei gew-öhnlicher Temperatur gearbeiret wird, und die Abscheidung des Alkalisulfates durch Aninioniak bewirkt wird.It has now been found that the sulfates mentioned can also be obtained from such Solutions through ammonia can separate in 'solid form, in which these sulfates from animonsulphate and other compounds of the fixed alkalis by double Ability to implement. It is known (see e.g. G ni e 1 i n - IL r a tt t, j. Edition, Vol. Il, i, p.48 below and p. 322) that by dop = Kelte Implementation of amnion sulfate with common salt or sodium nitrate \ atriunisulfat in the can suck out flitze. However, this is different from this known method that of the present application by working at ordinary temperature and the deposition of the alkali sulfate is effected by anionic acid.
Man verfährt z. B. in der Weise, daß inan gesättigte Lösungen, welche Aninionsulfat und Salze der fixen Alkalien, wie Chtoricle, Nitrate usw. in annähernd äquivalenten Mengen enthalten, miteinander vermisch, und alsdann gasförmiges Ainnioniak einleitet. Dabei scheiden sich die Sulfate der fixen Alkalien in kristallinischer Form ab. Das ausgeschiedene Salz wird von der Mutterlauge getrennt und in bekannter Weise weiterverarbeitet.One proceeds z. B. in such a way that inan saturated solutions, which Aninion sulfate and salts of the fixed alkalis, like chloricle, nitrates etc. in approximate contain equivalent amounts, mixed with one another, and then gaseous ammonia initiates. The sulfates of the fixed alkalis separate into crystalline ones Shape. The precipitated salt is separated from the mother liquor and in known Way processed.
Aus der -2#Iti tterlauge können die entsprechenden Ainmonsalze in bekannter Weise gewonnen werden.The corresponding ammonium salts can be obtained from the -2 # ether liquor in can be obtained in a known manner.
Au sfiihrungsbeispiele.Execution examples.
i. 1lan vermischt 3,5 kg Arnmonsulfatlauge von 2S,5° Be mit 5,5 kg einer gesättigten Kochsalzlösung. In diese L%Iischlauge leitet man gasförmiges Ammoniak, bis die Mutterlauge ein spezifisches Gewicht von etwa o,95 zeigt. In dem Maße, wie das Ammoniak von der Flüssigkeit aufgenommen wird, scheidet sich Natriumsulfat ab, welches schließlich von der Mutterlauge getrennt wird.i. 1lan mixes 3.5 kg of ammonium sulphate liquor from 2S, 5 ° Be with 5.5 kg a saturated saline solution. Gaseous ammonia is passed into this liquor, until the mother liquor shows a specific gravity of about 0.95. To the extent that the ammonia is absorbed by the liquid, sodium sulfate separates, which is finally separated from the mother liquor.
2. Man leitet in eine Lösung, die nian durch Zusammengießen von 3,51:g Animonsulfatlauge von 28,5° Be und <i,3 lcg Kaliumchloridlauge von 22° Be erhält, gasförmiges Amnioniak bis zur Sättigung ein, indem man durch Kühlung dafür sorgt, daß die gewöhnliche Temperatur nicht wesentlich überschritten n-ird. Das ausgefällte Sulfat wird von der 1lutterlauge getrennt. Man kann so bequem oo Prozent und darüber von dein angewandten Chlorkalium in I#',alitinistilfat überführen.2. One passes into a solution which can be obtained by pouring together 3.51: g Animonsulphate liquor of 28.5 ° Be and <1.3 lcg potassium chloride liquor of 22 ° Be obtained, gaseous amnionia to saturation by cooling it to ensure that that the usual temperature is not significantly exceeded. The precipitated one Sulphate is separated from the mother liquor. You can comfortably oo percent and above Convert your applied potassium chloride into I # ', alitinistilfate.
