  Verfahren zur beschleunigten Fabrikation von Natriumbikarbonat. 



   Den Gegenstand des vorliegenden Patentes bildet ein Verfahren zur Herstellung von Bikarbonat, vermittels Durchleiten eines   Stromes   von   gasförmiger Kohlensäure   durch eine hinreichend konzentrierte LÖsung von Natriumkarbonat. Der Zweck des Verfahrens ist es, diese Reaktion, die, wie bekannt,   ziemli h langsam vor sich geht,   zu beschleunigen. Die Langsamkeit der Reaktion ist an sich durch die   Tatsache bedingt, dass   bei der Verwandlung des Monokarbonates in das Bikarbonat nur 0, 85 Kalorien frei werden. In der praktischen Ausführung wird die Reaktion noch weiter verlangsamt, wenn man   verdünnte     Kohlensäuregase, wie beispielsweise Kalkofen-   gase verwendet. 



   Das neue Verfahren beruht nun auf der Verwendung eines chemischen Agens, welches als Übertragungssubstanz derartig wirkt. dass es die Kohlensäure zunächst absorbiert, dabei ein merklich leichter lösliches Salz als das Natriumbikarbonat bildet und im Verlauf des Verfahrens seine Kohlensäure durch   sekundäre Umsetzung   an das Monokarbonat abgibt und so wieder für neue Kohlensäureaufnahme frei wird.

 karbonates wiederholt sich so immer. bis schliesslich kein neutrales Natriumkarbonat mehr vorhanden ist. Es liegt also eine Art katalytische Reaktion vor, insofern, als das Ammoniaksalz ohne Änderung seines Zustandes oder seiner Konzentration theoretisch genommen unbegrenzte Mengen Natriumkarbonat in schneller Reaktion in das Bikarbonat überführt. Das Ammoniak bezw.

   Ammoniumkarbonat dient also nur zur Fixierung und Übertragung der Kohlensäure auf das Natriumkarbonat.

  Process for the accelerated manufacture of sodium bicarbonate.



   The subject of the present patent is a process for the production of bicarbonate by passing a stream of gaseous carbonic acid through a sufficiently concentrated solution of sodium carbonate. The purpose of the procedure is to speed up this reaction, which is known to be rather slow. The slowness of the reaction is due to the fact that when the monocarbonate is converted into bicarbonate, only 0.85 calories are released. In practice, the reaction is slowed down even further if dilute carbonic acid gases, such as lime kiln gases, are used.



   The new method is based on the use of a chemical agent which acts as a transfer substance. that it first absorbs the carbonic acid, thereby forming a noticeably more soluble salt than the sodium bicarbonate, and in the course of the process releases its carbonic acid through secondary conversion to the monocarbonate and is thus released again for new carbonic acid absorption.
 EMI1.1
 carbonates is repeated over and over again. until finally there is no more neutral sodium carbonate. So there is a kind of catalytic reaction, insofar as the ammonia salt, theoretically speaking, converts unlimited amounts of sodium carbonate into bicarbonate in a rapid reaction without changing its state or its concentration. The ammonia respectively.

   Ammonium carbonate therefore only serves to fix and transfer the carbonic acid to the sodium carbonate.
