Description
Verfahren zur Herstellung von festem, in Wasser löslichem, basischem Aluminiumacetat und Aluminiumformiat. Es sind eine ganze Reihe basischer Aluminiumacetate bekannt, die teils in löslicher, teils in unlöslicher Form existieren können. Hierbei werden verschiedene Formen von Aluminiumacetaten erhalten, die auch bei hinsichtlich der Komponenten gleicher Zusammensetzung eine verschiedene Löslichkeit aufweisen, je nach der Temperatur und der Zeit, in welcher sie aus den wäBrigen Lösungen zur Ausscheidung gebracht werden, wobei allerdings der Gehalt des Kristallwassers ein verschiedener ist. Die Haltbarkeit der basischen Aluminiumacetatlösungen ist aber auch nicht unbeschränkt, so daß man sie durch besondere Zusätze zu verbessern gesucht hat. Dagegen sind zur Zeit in der Technik noch keine völlig wasserlöslichen basischen Aluminiumformiate in fester Form bekannt geworden. Wohl gibt das Patent 224074 die Herstellung eines neutralen Aluininiumformiates an, welches kristallinisch aus feuchtem Hydroxyd und 95prozentiger Ameisensäure gewonnen wird. Dieses soll aber nur bei Gegenwart freier Säure beständig sein. Nach dein Verfahren des Patentes 263865 soll ein basisches Aluminiumforiniat in trockner Form durch Verwendung von Tonerdehydrat mit wasserfreier Ameisensäure von i2o° gewonnen werden. Ein im Handel befindliches Produkt trocknen Aluminiuinformiates erweist sich als nicht völlig wasserlöslich, sondern nur zum Teil unter Hinterlassung eines bedeutenden unlöslichen Rückstandes.Process for the production of solid, water-soluble, basic Aluminum acetate and aluminum formate. There are a number of basic aluminum acetates known, which can exist partly in soluble, partly in insoluble form. Here different forms of aluminum acetates are obtained, which also with regard to the components of the same composition have different solubilities, depending on the temperature and the time in which it is removed from the aqueous solutions Excretion are brought, although the content of the water of crystallization is different. The shelf life of the basic aluminum acetate solutions is also not unlimited, so that one sought to improve them with special additions Has. In contrast, there are currently no completely water-soluble basic ones in technology Aluminum formates have become known in solid form. Probably the patent 224074 gives the Production of a neutral aluminum formate, which is crystalline from moist Hydroxide and 95 percent formic acid is obtained. But this is only intended for Resistant to the presence of free acid. According to your method of patent 263865 should a basic aluminum formate in dry form using alumina hydrate obtained with anhydrous formic acid from i2o °. A commercially available one Dry product Aluminum formates are not completely soluble in water, but only partially leaving a significant insoluble residue.
Es wurde nun die überraschende Beobachtung gemacht, dati man sowohl Lösungen von basischem Aluminiumacetat wie Aluminiumformiat, die in bekannter Weise, z. B. durch Umsetzung von Aluminiumsulfat und Bleiacetat oder von schwefelsaurer Tonerde, Ameisensäure und Kalk, oder auch nach anderen Verfahren gewonnen werden, in eine feste, dauernd haltbare trockne Form überführen kann, wenn die Überführung durch Trocknung mittels eines der an sich bekannten Zerstäubungsverfahren vorgenommen wird. Hierbei bleibt sowohl das basische Aluminiumforiniat wie das Acetat völlig wasserlöslich und ist durch Zugabe von Wasser in die ursprüngliche wäßrige Lösung wieder überzuführen, während die gleiche Lösung von Aluminiumformiat in normaler Weise oder unter vermindertem Druck verdampft, sich unter Ausscheiden basischer Aluminiumhydrate zersetzt, wogegen basische Aluminiumacetate für dauernde gute Löslichkeit besonderer Zusätze bedürfen. Beispiel. Man nehme eine technische Lösung von ameisensaurer Tonerde und zerstäube sie mit einem der gewöhnlichen Zerstäubungstrocken-The surprising observation has now been made that both Solutions of basic aluminum acetate such as aluminum formate, which in a known manner, z. B. by reacting aluminum sulfate and lead acetate or sulfuric acid Alumina, formic acid and lime, or obtained by other methods, can convert into a solid, permanently durable dry form when the transfer carried out by drying by means of one of the atomization methods known per se will. Both the basic aluminum formate and the acetate remain complete water soluble and is added to the original aqueous solution by adding water transferring again while the same solution of aluminum formate in normal Evaporated way or under reduced pressure, precipitating more basic Aluminum hydrates decompose, whereas basic aluminum acetates ensure good permanent solubility require special additives. Example. Take a technical solution from formic acid Clay and atomize it with one of the ordinary atomizing dry
