Description
Herstellung von Kaliumbicarbonat bzw. Kaliumcarbonat Bekanntlich stellt man Kaliumcarbonat hauptsächlich nach dem Magnesiumverfahren oder aus mit Hilfe der Elektrolyse gewonnenem Ätzkali dar. Im folgenden wird ein neues Verfahren zur Erzeugung von Kaliumbicarbonat bzw. Kaliumcarbonat beschrieben.Production of potassium bicarbonate or potassium carbonate is known to represent one potassium carbonate mainly after the magnesium process or from with the help the electrolysis obtained caustic potash. The following is a new method for Described generation of potassium bicarbonate or potassium carbonate.
Läßt man Ammonbicarbonat oder Ammoncarbonat auf sekundäres Kaliumorthophosphat in wäßriger Lösung einwirken, so erhält man als Bodenkörper Kaliumbicarbonat und Kaliumcarbonat oder ein Gemisch dieser. Die miteinander reagierenden -Substanzen können auch als Bodenkörper vorhanden sein. Nach dem Absondern des entstandenen Bodenkörpers enthält die Mutterlauge alles P;; O, neben etwas Ammoniak und Kohlensäure. Diese Lauge kann in den im Patent 540 077 beschriebenen Prozeß eingeführt werden oder z. B. nach dem Eindampfen als Düngemittel Verwendung finden.If ammonium bicarbonate or ammonium carbonate is allowed to act on secondary potassium orthophosphate in aqueous solution, potassium bicarbonate and potassium carbonate or a mixture of these are obtained as the sediment. The substances that react with one another can also be present as soil bodies. After the resulting sediment has been separated off, the mother liquor contains all of the P ;; Oh, next to some ammonia and carbonic acid. This liquor can be introduced into the process described in patent 540 077 or e.g. B. can be used as fertilizer after evaporation.
Beispiel Mol sekundäres Kaliumorthophosphat wurde in 25 ccm Wasser von t$° C gelöst, '/", Mol Ammoniumbicarbonat zugegeben und gerührt. Nach einiger Zeit wurde der Bodenkörper abfiltriert. Sein Gewicht betrug etwa 5 g. Er bestand zu 9.4 °/" aus Kaliumbicarbonat und zu 6 "/" aus Pottasche. Das Kaliumbicarbonat kann auf bekannte Weise in Pottasche verwandelt werden. Der Umsatz verläuft etwa nach KZHP04 -f- (NHa)2COa -'t- 2 H20 - KHC03 --F KH,P04 + 2 NH40H, wobei die Bildung von K=C03 nicht berücksichtigt ist.Example mole of secondary potassium orthophosphate was added to 25 cc of water of t $ ° C dissolved, '/ ", mol of ammonium bicarbonate added and stirred. After a few Time the sediment was filtered off. Its weight was about 5 g. He passed 9.4 ° / "from potassium bicarbonate and 6" / "from potash. The potassium bicarbonate can be transformed into potash in a known way. The turnover is about according to KZHP04 -f- (NHa) 2COa -'t- 2 H20 - KHC03 --F KH, P04 + 2 NH40H, whereby the formation of K = C03 is not taken into account.
Man kann in geschlossenen oder offenen Gefäßen arbeiten und die etwa entweichenden, Ammoniak und Kohlensäure enthaltenden Gase und Dämpfe auffangen und verarbeiten. Auch kann man unter einem Überdruck von Kohlensäure oder Ammoniak arbeiten.You can work in closed or open vessels and that about collect escaping gases and vapors containing ammonia and carbonic acid and to process. You can also work under excess pressure of carbonic acid or ammonia.
