Description
<Desc/Clms Page number 1>
Verfahren um das bei der Solvay'schen Reaktion erzeugte Natliumbikarbonat und
Ammoniumchlorid in wechselnder Reihenfolge auszufällen.
Zur Gewinnung von saurem kohlensauren Natrium und Ammoniumchlorid in wechselnder Aufeinanderfolge durch Fällung beider Salze aus der gemeinsamen Flüssigkeit kann man sich der nachstehend kurz in Erinnerung gebrachten Arbeitsweise bedienen.
Gegenstand der Erfindung ist ein Verfahren, durch welches die dieser bekannten Arbeitsweise anhaftenden Übelstände beseitigt werden. Zum richtigen Verständnis der neuen Verfahrensweise ist ein näheres Eingehen auf den bekannten Arbeitsmodus (D. R. P. 36093) unerlässlich : a) In die gemäss den unten gegebenen Erläuterungen gewonnenen, Ammoniumchlorid und Kochsalz enthaltenden Mutterlaugen wird nach vorgenommener Filtration Ammoniak und Kochsalz in geeigneter.
Menge zugesetzt. b) Darauf wird die Lösungmit Kohlensäure behandelt (karbonisiert), indemmanhiebei die Temperatur auf geeigneter Höhe hält. Sobald sich das Ammoniummonokarbonat bildet, wird die Karbonisierung eingestellt.

Process around the sodium bicarbonate produced in the Solvay reaction and
Precipitate ammonium chloride in alternating order.
To obtain acidic carbonate of sodium and ammonium chloride in alternating succession by precipitating both salts from the common liquid, the procedure briefly mentioned below can be used.
The subject of the invention is a method by which the deficiencies inherent in this known mode of operation are eliminated. For a correct understanding of the new procedure, a closer look at the known working mode (D. R. P. 36093) is essential: a) In the mother liquors containing ammonium chloride and common salt obtained according to the explanations given below, ammonia and common salt are appropriately filtered after filtration.
Amount added. b) The solution is then treated with carbonic acid (carbonized) by keeping the temperature at a suitable level. As soon as the ammonium monocarbonate forms, the carbonation is stopped.
