KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bekanntlich ist Knochenmehl als Düngemittel wegen seiner Schwerlöslichkeit so angefeindet worden, daß es kaum mehr verkäuflich ist. Gegenstand der vorliegenden Erfindung ist die Überführung von Knochenmehl in eisenhaltige Verbindungen, die den Vorzug der leichteren Löslichkeit und Aufnahme vor ähnlichen Präparaten, wie z. B. dem verschmolzenen Eisenphosphat der Thomasschlacke, haben.As is well known, bone meal is so hostile as a fertilizer because of its poor solubility become that it can hardly be sold any more. Subject of the present Invention is the conversion of bone meal into iron-containing compounds that the Advantage of the easier solubility and absorption over similar preparations, such as. B. the fused iron phosphate of the Thomas slag.
Die Erfindung beruht aμf der nicht vorherzusehenden Erkenntnis, daß sich der phosphorsaure Kalk im Knochenmehl mit Lösungen von Eisenchlorid, \ron schwefelsaurem wie von salpetersaurem Eisenoxyd -— auch in Gegenwart freier Säure, wie Schwefelsäure — in phosphorsaures Eisenoxyd unter entsprechender Bildung von Chlorcalcium, schwefelsaurem Kalk' bezw. salpetersaurem Kalk quantitativ umsetzt.The invention is based aμf the non-foreseeable realization that the phosphate of lime in the bone flour with solutions of iron chloride, \ r on sulphate as of nitrate of iron oxide - in the presence of free acid such as sulfuric acid - in phosphate of iron oxide with a corresponding formation of calcium chloride, sulphate Lime 'resp. Quantitatively converts nitric acid lime.
Diese Umsetzung erscheint insofern überraschend, weil dieselbe zwar bei präzipitiertem phosphorsauren Kalk leicht eintritt (vergl. die britische Patentschrift 2236/1873), indessen bei Knochenasche und Floridaphosphat gar nicht oder nur teilweise erfolgt. Der präzipitierte phosphorsaure Kalk ist jedoch als Ausgangsprodukt im Verhältnis zu dem Preise der natürlichen Kalkphosphate so teuer, daß er zur Gewinnung von Ferriphosphat als Düngemittel nicht in Betracht kommt.This implementation appears surprising because the same is true in the case of precipitated phosphoric acid lime easily enters (see British patent specification 2236/1873), however In the case of bone ash and Florida phosphate, it does not take place at all or only partially. However, the precipitated phosphoric acid lime is as a starting product in relation to the price of natural lime phosphates so expensive that it cannot be used as a fertilizer for the production of ferric phosphate.
Zur Ausführung der Erfindung wird zu Knochenmehl oder Knochenkohle die konzentrierte Lösung eines Eisenoxydsalzes zugesetzt, zAveckmäßig so lange, bis eine Verfmssigung stattfindet. Nach einiger Zeit wird die Masse fest; bei den Chlorid- bezw. Nitratpräparaten wird nunmehr das entstandene Chlorcalcium oder Calciumnitrat in bekannter Weise mit Wasser ausgewaschen.To carry out the invention, bone meal or charcoal is concentrated A solution of an iron oxide salt was added, zAveck-wise, until it was softened takes place. After a while the mass becomes solid; with the chloride respectively. Nitrate supplements the resulting calcium chloride or calcium nitrate is now washed out in a known manner with water.
Das so aus Knochenmehl erhaltene, fein verteilte, gefällte phosphorsaure Eisenoxyd ist äußerst leicht löslich in verdünnten Säuren und einzelnen Salzlösungen und daher von einem viel höheren ökonomischen Werte als das phosphorsaure Eisenoxyd der Thomasschlacke, das erst durch äußerst feine Mahlung zu einem brauchbaren Düngemittel wird.The finely divided, precipitated phosphoric acid iron oxide obtained in this way from bone meal is extremely easily soluble in dilute acids and individual salt solutions and therefore of a much higher economic value than the phosphoric acid iron oxide of the Thomas slag, which only becomes a usable fertilizer through extremely fine grinding.
Mittels dieses Verfahrens gelingt es, das als Düngemittel überaus wertvolle Ferriphosphat in billigster Weise herzustellen und gleichzeitig dem wegen seiner Schwerlöslichkeit entwerteten Knochenmehl ein neues Verwendungsgebiet zu erschließen.This process makes it possible to use ferric phosphate, which is extremely valuable as a fertilizer to manufacture in the cheapest way and at the same time because of its poor solubility devalued bone meal to open up a new area of application.
