Verfahren zur Herstellung von Eisenoxyd.
EMI1.1
<Desc/Clms Page number 2>
Wie aus der Zeichnung ersichtlich, können auch zwei oder mehrere Gefässe A serienweise angeordnet sein. Es empfiohlt sich in diesem Falle, für die Luft und Kohlensäure, die hintereinander durch sie hindurchgedrückt worden, falls erforderlich, zwischen je zwei Gefässe einen Kondensator anzuordnen.
Das Kohlensäuregas CO) und die Luft werden durch die Flüssigkeit unter Druck
EMI2.1
Da sich die Kalziumbikarbonatlösung in einer Lösung von Ferrochlorid (Fe Cl2) befindet, so fällt sie das Eisen alsbald als Karbonat (Fe CO3) aus, unter Bildung von Kohlensäure- gas und Wasser. Das hiebei entstehende CC bildet wieder H2 C03, welches seinerseits wieder den Kalk zersetzt und eine weitere Ausfällung des Eisens herbeiführt, bis die Operation beendet ist.
Das so gebildete Ferrokarbonat (Fe CO3) oxydiert sich im Ausgenblicke seiner Bildung
EMI2.2
geblasen wird, wobei der Oxydationsprozess durch die mittels Dampf bewirkte Erhitzung der Masse auf zirka 850 C und Erhöhung des Druckes auf etwa 1'4 bis 2. 1 Atm. be- schleunigt wird.
Viele chloridhaltige Flüssigkeiten enthalten Manganverbindungen, z. B. Manganchlorid, welch letzteres während der Behandlung zum Teif zu Manganoxyd oxydiert wird.
Würde man diesem Produkt gestatten, in dem Eisenhydrat zurückzubleiben, so würde dies den Wert der Kalzinierung beeinträchtigen. Das entstehende Oxyd würde geringwertig werden, da es von bräunlicher Farbe sein würde, wodurch es z. B. als Farbe minderwertig ist.
EMI2.3
Erflndung zweekmässig mit Chlorwasserstoffsäure, durch welche die etwa vorhandenen Manganverbindungen in Manganchlorid übergeführt werden. Man lässt absetzen und entfernt die Manganchloride durch Dekantieren. Dieselben können auf Siena und Umbra verarbeitet werden.
Es gelingt in der beschriebenen Weise, ein praktisch reines Ferrihydrat, Fe2 (OH)6 herzustellen. Dieses Produkt wird gewaschen, zu dem Zwecke, alle löslichen Satze zu ent- fernen, filtriert, getrocknet und in einem geeigneten Ofen kalziniert und man erhält so ein hochklassiges, als rein zu bezeichnendes 97- bis 98%iges Ferrioxyd (Fe2 Og).

Process for the production of iron oxide.
EMI1.1
<Desc / Clms Page number 2>
As can be seen from the drawing, two or more vessels A can also be arranged in series. In this case it is advisable to place a condenser between two vessels for the air and carbon dioxide that have been pushed through them one after the other.
The carbon dioxide gas CO) and the air are pressurized by the liquid
EMI2.1
Since the calcium bicarbonate solution is in a solution of ferrochloride (Fe Cl2), the iron soon precipitates as carbonate (Fe CO3) with the formation of carbonic acid gas and water. The resulting CC forms H2 CO3 again, which in turn decomposes the lime and causes further precipitation of the iron until the operation is finished.
The ferro carbonate (Fe CO3) formed in this way is oxidized in the moment of its formation
EMI2.2
is blown, the oxidation process being caused by the heating of the mass by means of steam to around 850 C and an increase in pressure to around 1'4 to 2.1 atm. is accelerated.
Many chloride containing liquids contain manganese compounds, e.g. B. Manganese chloride, the latter being partially oxidized to manganese oxide during the treatment.
Allowing this product to remain in the iron hydrate would detract from the calcination value. The resulting oxide would be of little value since it would be brownish in color, making it e.g. B. is inferior as color.
EMI2.3
Two-way invention with hydrochloric acid, through which any manganese compounds present are converted into manganese chloride. It is allowed to settle and the manganese chlorides are removed by decanting. The same can be used on sienna and umber.
It is possible in the manner described to produce a practically pure ferric hydrate, Fe2 (OH) 6. This product is washed, for the purpose of removing all soluble deposits, filtered, dried and calcined in a suitable oven and a high-quality, pure ferric oxide (Fe2Og) is obtained.
