Patentiert im Deutschen Reiche vom 24. März 1916 ab.Patented in the German Empire on March 24, 1916.
Es ist bekannt, daß Natriumbisulf at beim Erhitzen auf höhere Temperatur in Sulfat einerseits, Schwefelsäureanhydrid und Wasser andererseits,It is known that sodium bisulfate turns into sulfate when heated to a higher temperature on the one hand, sulfuric anhydride and water on the other,
2;Na H SO4 = Na2 SO4 -+-SO3 + H2O,2 ; Na H SO 4 = Na 2 SO 4 - + - SO 3 + H 2 O,
zerfällt.disintegrates.
Die technische Durchführbarkeit dieser Reaktion zur Gewinnung der SchwefelsäureThe technical feasibility of this reaction to obtain sulfuric acid
ίο scheiterte bisher an der geringen Widerstandsfähigkeit der für die Destillationsapparatur in Frage kommenden Materialien, nämlich Eisen und Chamotte.ίο failed so far because of the low resistance the materials suitable for the distillation apparatus, namely iron and chamotte.
Durch Zusatz teils von indifferenten Körpern, wir Sulfat, teils von chemisch wirksamen, wie Sand, Ton, Kohle, hat man die .schädlichen Einflüsse der Schmelze zu beseitigen versucht. Wenn auch hierbei ein gewisser A^orteil erzielt wird, so entsteht doch hierdurch in jedem Fall ein nicht unbeträchtlicher Aufwand an mechanischer Arbeit. Bei Anwendung von Sand, Ton usw. als Zusatz muß man z. B außerdem auf ein gut poröses, leicht verkäufliches Sulfat verzichten.By adding partly indifferent bodies, we sulfate, partly chemically active, like sand, clay, coal, the harmful effects of the melt have to be eliminated tries. Even if a certain advantage is achieved here, it does arise from it in any case, a not inconsiderable amount of mechanical work. When using sand, clay, etc. as an additive you have to z. B also do without a well-porous, easily salable sulfate.
Nach einem anderen Vorschlag soll das geschmolzene Bisulfat durch heiße Luft unter Zugabe von Wasserdampf, fein zerstäubt und hierdurch im Sinne obiger Gleichung ersetzt werden. Wesentlich soll hierbei die Mitwirkung des Wasserdampfes sein; in diesem Falle ist die direkte Gewinnung von konzentrierter Säure natürlich ausgeschlossen.According to another suggestion, the melted bisulfate is to be submerged by hot air Addition of water vapor, finely atomized and be replaced by this in the sense of the above equation. Participation should be essential here be of water vapor; in this case the direct extraction of is more concentrated Acid excluded, of course.
Es wurde nun gefunden, daß Alkalibisulfat, wie Kalium- oder Natriumbisulf at, ohne jeglichen Zusatz und in.jeder Form, wie es fällt, in dem in der Cement- oder sonstigen chemischen Industrie heute allgemein üblichen Drehrohrofen quantitativ in seine Komponenten sich spalten läßt.It has now been found that alkali bisulfate, such as potassium or sodium bisulfate, without any addition and in any form, such as it falls, which is common today in the cement or other chemical industry Rotary kiln can be split quantitatively into its components.
Ein Angriff des Ofenfutters (Chamotte oder sonst ein feuerfestes Material) erfolgt bei dieser Ausführung des Prozesses nicht oder nur in ganz geringem Maße.The furnace lining (chamotte or other refractory material) is attacked in this execution of the process not or only to a very small extent.
.Die Art der Feuerung, ob öl-, Teer- oder Generatorfeuer, ist nicht von Einfluß, ein Ankrusten des Gutes' wird durch Einbau eines Kratzers oder Schabers in der heißen Zone des Ofens vermieden.The type of firing, whether oil, tar or Generator fire, has no influence, an encrustation the good 'is created by installing a scraper or scraper in the hot zone of the furnace.
Vor dem Verfahren der Patentschrift 274873, Kl. 12, wonach Sulfat aus Bisulfat in ununterbrochenem Betrieb in einem Ofenraum hergestellt wird, hat das vorliegende große Vorteile. Das bekannte Verfahren gestattet zwar die Gewinnung von' ,Schwefelsäure und Sulfat aus Bisulfat in ununterbrochenem Betriebe, es zeigen sich jedoch in den Eigenschaften zwischen dem nach diesem Verfahren und dem vorliegenden hergestellten Sulfat wesentliche Unterschiede. Nach dem neuen Verfahren wird das Sulfat in lockerer, poröser Form erhalten, ohne den Schmelzzustand erreicht zu haben. Es verläßt in diesem Zustand den Ofen und ist direkt für.die Glasindustrie verwendungsfähig, während das nach dem bekannten Verfahren erhaltene Produkt nur als eine dünne Schmelze aus dem Ofen abgezogen werden kann. Nach dem Erstarren bildet es eine feste Masse, die in dieser Form, selbst nach bester Mahlung,' für die Glasindustrie, dem Hauptverwendungszweck des Bisulfats, nicht verwendbar ist.Before the process of patent specification 274873, class 12, according to which sulfate from bisulfate in continuous operation in a furnace room, the present has great Advantages. The known method allows the production of ', sulfuric acid and Sulphate from bisulphate in continuous operations, however, it shows up in the properties there are significant differences between the sulfate produced by this process and the present. According to the new one In the process, the sulfate is obtained in a loose, porous form, without the melted state to have achieved. It leaves the furnace in this state and is directly for the glass industry usable, while the product obtained by the known process only as a thin melt from the Oven can be withdrawn. After solidifying, it forms a solid mass that is in this Form, even after the best grinding, 'for the glass industry, the main use of the bisulfate, is not usable.
