PATENTAMTPATENT OFFICE
Nach der Patentschrift Nr. 19784 erhält man beim Einleiten von Alkalibicarbonat in Alkalialuminat einestheils kohlensaures Alkalialuminat als Niederschlag, während einfach kohlensaures Alkali in Lösung bleibt.According to the patent specification No. 19784 one obtains when introducing alkali bicarbonate into alkali aluminate, it is partly carbonate alkali aluminate as a precipitate, while simply carbonate of alkali remains in solution.
Das kohlensaure Alkalialuminat findet in der Technik infolge seiner leichten Löslichkeit in Essigsäure Anwendung' zur Darstellung von Beizen in der Färberei und Druckerei. Hierbei wird in den meisten Fällen noch essigsaure Magnesia zugegeben.The carbonic acid alkali aluminate is found in technology due to its easy solubility in Acetic acid application 'for the representation of stains in dyeing and printing. Here In most cases, acetic acid magnesia is added.
Das kohlensaure Alkalialuminat, entsprechend der Formel:The carbonic alkali aluminate, according to the formula:
Al2 O3, K2 O, 2 C O2 + 5 H2 O
oder Al 2 O 3 , K 2 O, 2 C O 2 + 5 H 2 O
or
Al2 O3, Na2 O, 2 C O2 + 5 /Z2 O Al 2 O 3 , Na 2 O, 2 CO 2 + 5 / Z 2 O
bedarf zu seiner Lösung in Essigsäure auf ι Aequivalent dieser Verbindung 3 Aequivalente Essigsäure, wobei sich eine Mischung von essigsaurem Natron mit essigsaurer Thonerde bildet.requires 3 equivalents for one equivalent of this compound to dissolve it in acetic acid Acetic acid, which is a mixture of baking soda with alumina acetic acid forms.
Eine ähnliche, jedoch nicht ganz analoge Verbindung der Thonerde mit Kohlensäure und Magnesia erhält man durch Zugiefsen von Alkalialuminat in eine Lösung von Magnesiumbicarbonat oder umgekehrt, wobei sich kohlensaures Magnesiumaluminat ausscheidet und einfach kohlensaures Alkali in Lösung bleibt. Diese Zersetzung geht nach folgender Formel vor sich:A similar, but not entirely analogous, compound of alumina with carbonic acid and magnesia is obtained by pouring alkali aluminate into a solution of magnesium bicarbonate or vice versa, with carbonate of magnesium aluminate precipitating and simply carbonate of alkali remains in solution. This decomposition is based on the following formula in front of you:
Al2 O3K2O+ Mg(H C OJ9+-2 H2 O = Al2 O3 Mg C O3, 3 H2 O + K2 C O3 Al 2 O 3 K 2 O + Mg (HC OJ 9 + -2 H 2 O = Al 2 O 3 Mg C O 3 , 3 H 2 O + K 2 C O 3
Al2 O8 Na2 0 + Mg(HC O3J2 + 2 H2 O
= Al2 O3 Mg CO3, 2,H2O+ Na2 C O3. Al 2 O 8 Na 2 0 + Mg (HC O 3 J 2 + 2 H 2 O
= Al 2 O 3 Mg CO 3 , 2, H 2 O + Na 2 C O 3 .
Die Darstellung von Alkalialuminat, sowie diejenige von Magnesiumbicarbonat sind hinlänglich bekannt und brauchen hier nicht näher beschrieben zu werden.The representation of alkali aluminate, as well as that of magnesium bicarbonate are sufficient known and need not be described in more detail here.
Zur Darstellung des kohlensauren Magnesiumaluminats genügen die einfachsten Vorkehrungen, z. B. ein Fällbottich, worin die beiden Stoffe zusammengebracht werden.The simplest precautions are sufficient for the preparation of the carbonate of magnesium aluminate, z. B. a felling vat, in which the two substances are brought together.
Hat man nicht fertiges Magnesiumbicarbonat, so kann man sich auch einer Milch von Magnesia oder Magnesiumcarbonat bedienen, die man mit dem Alkalialuminat unter gleichzeitigem Einleiten von Kohlensäure zusammenbringt. Die Beendigung der Reaction läfst sich leicht feststellen, indem man eine dem Fällgefäfs entnommene Probe abfiltrirt und sich durch Zusatz einiger Tropfen der zufiiefsenden Flüssigkeit (Alkalialuminat oder Magnesiumbicarbonat) überzeugt, ob noch ein Niederschlag entsteht oder nicht, wobei darauf zu achten ist, dafs schliefslich ein kleiner Ueberschufs von Magnesiumcarbonat vorhanden ist.If you have not finished magnesium bicarbonate, you can also have a milk of magnesia or use magnesium carbonate, which you can use with the alkali aluminate at the same time Introducing carbonic acid brings together. The reaction can be terminated easily ascertained by filtering off a sample taken from the precipitation vessel and by adding a few drops of the liquid to be added (alkali aluminate or magnesium bicarbonate) convinced whether a precipitate still occurs or not, whereby towards it it must be ensured that there is ultimately a small excess of magnesium carbonate.
Der entstandene Niederschlag wird von. der Lösung getrennt, am besten durch Filterpresse, in dieser gewaschen und dann bei 70 bis 80° C. getrocknet, wobei er als weifse hornartige Masse erscheint, die in Wasser unlöslich, in Säuren dagegen unter Entwickelung von Kohlensäure löslich ist.The resulting precipitate is of. separated from the solution, preferably by means of a filter press, washed in this and then dried at 70 to 80 ° C., whereby it is as white horn-like Mass appears which is insoluble in water, but in acids with the development of Carbonic acid is soluble.
Die Lösung von einfach kohlensaurem Alkali wird zweckmäfsig in die Fabrikation des Alkalialuminats zurückgenommen, nachdem der Ueberschufs von Magnesiumcarbonat durch Erhitzen abgeschieden und abfiltrirt worden ist; dieses kann ebenfalls wieder zur Darstellung von Magnesiumbicarbonat verwendet werden.The solution of simple carbonate of alkali is expedient in the manufacture of the alkali aluminate withdrawn after the excess of magnesium carbonate through Heating has separated and filtered off; this can also be used to represent Magnesium bicarbonate can be used.
Das kohlensaure Magnesiumaluminat hat folgende Zusammensetzung:The carbonic acid magnesium aluminate has the following composition:

Wie aus der Vergleichung hervorgeht, hat das kohlensaure Magnesiumaluminat vor den kohlensauren Alkalialuminaten folgende Vorzüge :As can be seen from the comparison, the carbonic acid magnesium aluminate has before the carbonate alkali aluminates have the following advantages:
1. höherer Gehalt an Thonerde,1. higher content of alumina,
2. geringerer Bedarf an Essigsäure für die Lösung, indem man davon keine für Auflösung von Alkali braucht und den oben erwähnten besonderen Zusatz von essigsaurer Magnesia umgeht.2. Less need of acetic acid for the solution by not having any of it for dissolution of alkali and bypasses the special addition of acetic acid magnesia mentioned above.
