Description
Vorrichtung zur Herstellung flüchtiger Säuren Gegenstand der Erfindung ist eine Vorrichtung zur Herstellung flüchtiger Säuren.Apparatus for the production of volatile acids Subject matter of the invention is a device for the production of volatile acids.
Die Vorrichtung besteht aus einem am Boden des Gefäßes befindlichen Propeller und aus an der gleichen Welle angeordneten horizontalen Rührarmen, an welchen sich noch Schlagarme befinden. Bei Verwendung derartig ausgeführter Mischvorrichtungen ist man in der Lage, z. B. bei der Herstellung von Essigsäure aus Calciumacetat mit Schwefelsäure ohne irgendwelche Beimischung von Essigsäure als Verdünnungsmittel, einen leicht flüssigen Brei zu erhalten und eine praktisch quantitative Umsetzung des Calciumacetats zu Calciumsulfat und Essigsäure zu erreichen.The device consists of one located at the bottom of the vessel Propeller and horizontal agitator arms arranged on the same shaft which are still flapping arms. When using such designed mixing devices is one able to z. B. in the production of acetic acid from calcium acetate with sulfuric acid without any admixture of acetic acid as a diluent, to obtain a slightly liquid paste and a practically quantitative conversion from calcium acetate to calcium sulfate and acetic acid.
Bei der Umsetzung von Calciumformiat mit Schwefelsäure genügt schon eine Beimischung von Ameisensäure als Verdünnungsmittel in Höhe von 30 bis 6o 60% bezogen auf das angewandte Calciumformiat, während man bei der Verwendung bisher üblicher Vorrichtungen 100 0/0 und noch mehr Ameisensäure beimischen mußte, um zu einem entsprechend flüssigen Brei zu gelangen.When converting calcium formate with sulfuric acid, it is enough an admixture of formic acid as a diluent in the amount of 30 to 60% based on the calcium formate used, while one has been using it so far conventional devices 100 0/0 and even more formic acid had to add to to reach a correspondingly liquid pulp.
Aus der so hergestellten Mischung, z. B. von Calciumacetat und Schwefelsäure, kann die Essigsäure direkt, z. B. in einer angeschlossenen Destillierblase, abgetrieben werden. Man arbeitet jedoch vorteilhafter, wenn man die Mischung nicht auf einmal, sondern allmählich, auch ununterbrochen, in die Destillierblase einführt, und zwar in dem Maße, daß in der Blase stets ein trockener Gips vorhanden ist. From the mixture thus prepared, e.g. B. of calcium acetate and sulfuric acid, can the acetic acid directly, e.g. B. in a connected still, driven off will. However, it is more advantageous to work if you do not mix the mixture all at once, but gradually, even continuously, into the still, namely to the extent that there is always a dry plaster of paris in the bladder.
Die Mischvorrichtung der vorliegenden Erfindung läßt sich sinngemäß auch für die Umsetzung von salzsauren, ameisensauren, milchsauren und buttersauren Salzen mit dem gleichen Erfolg verwenden, wobei zur Umsetzung beliebige Mineralsäuren, wie Schwefelsäure, Phosphorsäure, verwendet werden können. The mixing device of the present invention can be analogously also for the conversion of hydrochloric acid, formic acid, lactic acid and butter acid Use salts with the same success, using any mineral acids, such as sulfuric acid, phosphoric acid can be used.
Auch kann man in dem Mischer bei gleichzeitiger Kühlung die organischen Salze mit Salpetersäure beliebiger Konzentration umsetzen, ohne daß Verluste durch Oxydation eintreten. Man erzielt dabei den Vorteil, daß man bei Anwendung von Kalksalzen wertvolle Nitrate erhält. You can also in the mixer with simultaneous cooling, the organic React salts with nitric acid of any concentration without causing losses Oxidation will occur. This has the advantage that when using lime salts receives valuable nitrates.
Auch die Flußsäure ist für die Umsetzung der organischen Salze durchaus geeignet. Hydrofluoric acid is also absolutely essential for the conversion of the organic salts suitable.
Durch deren Anwendung ist man in der Lage, aus den Alkalisalzen die wertvollen Alkalifluoride, wie Natriumfluorid und Kaliumfluorid, zu erhalten. By using them, one is able to convert the alkali salts valuable alkali fluorides such as sodium fluoride and potassium fluoride.
Beiliegende Zeichnung zeigt eine beispielsweise Ausführung eines Mischers. In dieser bedeutet I das Mischgefäß, 2 die Welle, 3 die horizontalen Rührarme, an welchen die Schlagarme 4 angeordnet sind, 5 den Propeller. The accompanying drawing shows an example of an embodiment Mixer. In this, I means the mixing vessel, 2 the shaft, 3 the horizontal agitator arms, on which the striking arms 4 are arranged, 5 the propeller.
Das Wesen der neuen Vorrichtung ist in der Kombination des an sich bekannten Propellers mit den für sich ebenfalls schon verschiedentlich benutzten horizontalen Rührarmen, die mit Schlagarmen ausgerüstet sind, zu erblicken. Die besonderen, im vorhergehenden geschilderten Effekte werden durch die neue Kombination dadurch erzielt, daß der am Boden des Gefäßes befindliche Propeller 5 die flüssige Masse aufwirbelt, während die Schlagarme 4 mit den Rührarmen 3 die auf der Flüssigkeit schwebenden Brocken der umzusetzenden Stoffe in den Wirbel der durch den Propeller bewegten Flüssigkeit werfen und so ein Schwimmen auf -der Oberfläche der Flüssigkeit unmöglich machen. The essence of the new device is in the combination of the per se well-known propellers with those that have already been used in various ways horizontal agitator arms equipped with striking arms. the special effects described above are created by the new combination achieved in that the propeller 5 located at the bottom of the vessel is the liquid The mass is whirled up, while the beater arms 4 with the agitator arms 3 are on the liquid floating chunks of the substances to be converted in the vortex caused by the propeller Throwing moving liquid and thus floating on the surface of the liquid to make impossible.
