Description

Verfahren zur Durchführung von chemischen Reaktionen zwischen Flüssigkeiten, die bei diesem Vorgang große Mengen von Gasen entbinden Das Zusammenbringen von Flüssigkeiten, die bei diesem Vorgang in Reaktion treten und dabei große Mengen von Gasen entbinden, ist von jeher schveerig gewesen. Daher gelingt es nicht, - mit den gewöhnlichlefn Mitteln der Technik leine gute Durchmischung solcher Flüssigkeiten herbeizuführen. Läßt man sie beispielsweise in ein mit einem Rührwerk ausgestattetes Gefäß einlaufen, so werden sie, noch ehe eine vollständige Vereilnigung erfolgt ist, durch die entstehenden Gase wieder aus dem Gefäß herausgeschleudert.Process for carrying out chemical reactions between liquids, which in this process release large amounts of gases The bringing together of Liquids that react during this process and in large quantities releasing gases has always been difficult. Therefore it does not succeed - such fluids cannot be thoroughly mixed by the ordinary means of technology bring about. If you let them, for example, in one equipped with a stirrer If the vessels run in, they will before complete union takes place is thrown out of the vessel again by the gases produced.

Die übliche Art des Mischens derartiger Flüssigkeiten besteht in dem Zusam,menlaufenlassen der Reaktionsteilnehmer in einem Rieselturm. Es hat sich jedoch gezeigt, daß hierbei sehr oft nebeneinander herlaufende Strömungsfäden entstehen, so daß der erreichte Grad der Mischung für viele Zwecke nicht genügt. Außerdem bedarf es sehr großer Räume für den Mischturm.The usual way of mixing such liquids is by Let the reaction participants run together in a trickle tower. It has, however shown that this very often results in flow threads running next to one another, so that the degree of mixing achieved is insufficient for many purposes. Also needs there are very large spaces for the mixing tower.

Es gelingt nun, wie gefunden wurde, eine praktisch vollkommene Vereinigung der beiden Flüssigkeiten ohne Verluste durch Schäumen zu erreichen, wenn man sie durch ein System übereinanderstehender Trichter hindurchlaufen läßt. Die Flüssigkeiten gelangen tangential in den Konus des obersten Trichters und - werden an seinem Mantel zu einer Flüssigkeitsschicht breitgezogen, die den Austritt der Gase erleichtert. Am unteren Teil des ersten Trichterkonus sammeln sich die jetzt schon teilweise gemischten Flüssigkeiten und laufen durch den Trichterschlund wiederum tangential in den Konus eines darunter befindlichen zeiten Trichters und von diesem gegebenenfalls in einen dritten und vierten Trichter usw. Man erreicht schließlich eine fast ideale Mischung der Flüssigkeiten, die gleichzeitig die entstandenen Gase abgegeben haben. It has now been found that a practically perfect union succeeds of the two liquids can be achieved without loss due to foaming if one uses them passes through a system of superposed funnels. The liquids get tangentially into the cone of the uppermost funnel and - become on its mantle Spread out into a liquid layer that facilitates the escape of the gases. They are already partially collecting on the lower part of the first funnel cone mixed liquids and run tangentially through the funnel throat into the cone of a time funnel underneath and from this if necessary into a third and fourth funnel, etc. One finally reaches one almost ideal mixture of liquids, which at the same time emit the resulting gases to have.

Die beiliegende Zeichnung zeigt eine Ausführungsform der für diese Mischung verwendbaren Apparatur. The accompanying drawing shows an embodiment of the for this Mixture usable apparatus.

Beispiel In der durch die beiliegende Zeichnung gekennzeichneten Apparatur werden Natriumnitritlösung und Salpetersäure zusammengegeben. Nach der Reaktionsgieichung 3 NaN 02 + 2 HNOJ = 3NaNO3+2NO+H20 entsteht hierbei gasförmiges Stickoxyd. Bei einem Durchmesser der Trichter am oberen Rande von 700 mm und einer Höhe von etwa 500 mm gelingt es, binnen 24 Stunden 3socbm Flüssigkeitsgemisch herzustellen. Um diese Leistung in einem mit Raschigringen gefüllten Rieselturm erreichen zu können, hätte es eines Turmes von einem Durchmesser von It/2m und einer Höhe von Vom bedurft, ohne daß. in diesem Turm die Vollständigkeit der Mischung erreicht worden wäre wie in der oben gekennzeichneten Trichterapparatur. Example In the one identified by the accompanying drawing Apparatus, sodium nitrite solution and nitric acid are combined. After Reaction equation 3 NaN 02 + 2 HNOJ = 3NaNO3 + 2NO + H20 this creates gaseous form Nitric oxide. With a diameter of the funnel at the upper edge of 700 mm and one Height of about 500 mm it is possible to produce 3socbm liquid mixture within 24 hours. In order to be able to achieve this performance in a trickle tower filled with Raschig rings, it would have required a tower with a diameter of It / 2m and a height of Vom, without. in this tower the completeness of the mix would have been achieved like in the funnel apparatus marked above.

Das Verfahren ist nicht auf die Durchführung dieser Umsetzung beschränkt, sondern bei allen Vorgängen anwendbar, bei denen beim Zusammengehen zweier Flüssigkeiten unter Reaktionsverlauf Gase entbunden werden. So kann man z. B. eine gesättigte Sodalösung mit 50 o/oiger Schwefelsäure in dieser Apparatur zu Natriumsulfatlösung und gasförmiger Kohlensäure umsetzen. Ebenso gelingt es auf diesem Wege, Natriumnitrat aus Sodalösung und Salpetersäure darzustellen. The procedure is not limited to carrying out this implementation, but can be used in all processes involving the merging of two liquids gases are released during the course of the reaction. So you can z. B. a saturated one Soda solution with 50% sulfuric acid in this apparatus to form sodium sulfate solution and convert gaseous carbonic acid. Sodium nitrate also succeeds in this way from soda solution and nitric acid.
