Description
Verfahren zur Herstellung von festem wasserlöslichem Aluminiumacetat aus offizineller essigsaurer Tonerdelösung Es hat bisher nicht an Versuchen gefehlt, Aluminiumacetat, das sich klar in Wasser döst, in fester Form herzustellen. So hat man sich besonders bemüht, aus offizinellen, essigsauren Toner.delösungen festes Aluminiumacetat zu erhalten.Process for the production of solid water-soluble aluminum acetate from officinal acetic alumina solution There has been no lack of attempts to Aluminum acetate, which dozes clear in water, in solid form. So had Particular efforts are made to make solid solutions from officinal, acetic acid toner solutions To obtain aluminum acetate.
Man ,hat bereits Aluminiumacetat aus Lösungen !bestimmten spezifischen Gewichts in Gegenwart freier Essigsäure zur Kristallisation gebracht. Man hat ferner Alumi.niumacetatlösungen von bestimmter Bas.izität auf verschiedene Weise eingedampft. Man hat unter Zusatz bestimmter Stoffe, wie Harnstoff, Thioharnstoff und ähnlichen, die essigsaure Tonerdelös ,ng zur Trockne ,gebracht, ohne jedoch in der Lage zu sein, aus offizineller essigsaurer Tonerdelösung .das Aluminiumacetat in fester, wasserlöslicher Form zu erhalten.One, already has aluminum acetate from solutions! Certain specific Weight brought to crystallization in the presence of free acetic acid. One also has Aluminum acetate solutions of a certain basicity evaporated in various ways. With the addition of certain substances, such as urea, thiourea and the like, the acetic acid clay solution, brought to dryness, but without being able to be, from officinal acetic acid alumina solution. the aluminum acetate in solid, in water-soluble form.
Es wurde nun ,gefunden, daß auch aus offizinellen essigsauren Tonendelbsunigen in überraschend einfacher Weise festes, in jedem gebräuchlichen Mengenverhältnis. vollkommen klar wasserlösliches Aluminiumacetat erhalten wird, wenn man die Tonerdelösu.ng nur kurze Zeit, zweckmäBigerweise 5 bis & Sekunden, erhöhten Temperaturen aussetzt und die Trockenprodukte sofort nach ihrer Bildung entfernt.It has now been found that clay elbows are also made from officinal acetic acid in a surprisingly simple manner solid, in any conventional proportion. completely clear, water-soluble aluminum acetate is obtained if one uses the alumina solution exposed to elevated temperatures for only a short time, expediently 5 to & seconds and removes the dry products immediately after their formation.
Man erreicht die Bildung dieses festen, klar wasserlöslichen Aluminiumacetats dadurch, daB man :die offizinelle essigsaure Tonerdelösung in feiner Verteilung auf Walzentrockner auf bringt, die auf io5 bis i25° vorgewärmt sind und deren Walzen bei eineue Durchmesser von 7o cm auf einer Drehzahl von acht Umdrehungen je Minute gehalten werden. Bei dieser Drehzaihl kommt man auf eine Verweil!zeit des Aluminiwmacetats auf den Walzen von 5 Sekunden.The formation of this solid, clearly water-soluble aluminum acetate is achieved by: the official acetic acid alumina solution in finer Distribution on drum dryers that are preheated to io5 to i25 ° and their rollers with a diameter of 70 cm at a speed of eight revolutions held every minute. At this speed you get a dwell time of the aluminum acetate on the rollers for 5 seconds.
Man erhält auf diese Weise ein Trockenprodukt in Form eines feinen Pulvers, .das sich vollkommen klar in jedem gebräuchlichen Mengenverhältnis in Wasser löst und dessen Lösungen wiederum der offizinellen essigsauren Tonerdelös.ung entsprechen. Die Drehzahl der Walzen .des Walzentrockners Ist natürlich abhängig von dem Durchmesser der Walzen, so daß bei, einem größeren Durchmesser auch die Drehzahl je Minute erhöht werden muß, während bei kleinerem. Durchmesser kleinere Drehzahlen erforderlich sind.In this way, a fine dry product is obtained Powder, .that is completely clear in every common proportion in water dissolves and its solutions in turn correspond to the officinal acetic acid alumina solution. The speed of the rollers of the roller dryer is of course dependent on the diameter of the rollers, so that with a larger diameter, the speed per minute also increases must be, while with smaller. Diameter lower speeds required are.
Es war nicht zu erwarten, .daß erfindungsgemäß aus o.ffizinelden essigsauren Tonerdelösunbgen feste, wasserlösliche Produkte erhalten würden, weil die Empfindlichkeit des offizinellen Aluminiumacetats gegen erhöhte Temperaturen bekannt ist und erhöhte Temperaturen in kurzer Zeit die Bildung .unlöslicher Acetate :hervorrufen.It was not to be expected that, according to the invention, from o.ffizinelden acetic acids Alumina solutions would get solid, water-soluble products because of their sensitivity of the officinal aluminum acetate against elevated temperatures is known and increased Temperatures can cause the formation of insoluble acetates in a short time.
Beispiel Eine nach den Vorschriften des DAB VI aus Aluminiutmsu.lfat, Essigsäure und Calciumcarbonat hergestellte und gereinigte Lösung von essigsaurer Tonerde wird, durch Düsen in feiner Verteilung auf den Zylinder eines Walzentrockners, der mit Dampf von 1,.5 atü geheizt ist, aufgesprüht. In üblicher Weise wird aan geeigneter Stelle des Zylin, ders .der entstandene Rückstand mit einem gut anliegenden Schaber und zweckmäßig unter Absaugung abgenommen.EXAMPLE A solution of acetic alumina prepared and purified from aluminum sulphate, acetic acid and calcium carbonate according to the regulations of DAB VI is sprayed through nozzles in fine distribution onto the cylinder of a drum dryer heated with 1.5 atmospheric steam. In the usual way, at a suitable point in the cylinder, the resulting residue is removed with a well-fitting scraper and, appropriately, with suction.
