KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Das Verfahren bezweckt die Herstellung von Eisenchlorid in transportfähiger Form und geeignet zur Behandlung der Spülwässer von Aborten etc. und anderen unreinen Gewässern. Zur Ausführung der Erfindung krystallisirt man das Eisenchlorid gemeinsam mit schwefelsaurem Natron (Glaubersalz); das letztere schützt das Eisenchlorid vor dem auflösenden Einflufs der Atmosphäre.The purpose of the process is to produce ferric chloride in a transportable and suitable form for the treatment of flushing water from abortions etc. and other unclean waters. To carry out the invention, the iron chloride is crystallized together with sulfuric acid Baking soda (Glauber's salt); the latter protects the ferric chloride from the dissolving influence the atmosphere.
Die Operation wird wie folgt ausgeführt: Man nimmt Chlornatrium und vermischt es innigst mit so viel fein gepulvertem Eisenoxyd, dafs das Eisen genügt, um das gesammte im Natriumchlorid vorhandene Chlor zu binden und hierdurch Eisenchlorid zu erzeugen. Als Chlornatrium verwendet man gewöhnliches Salz (Siedesalz), welches bis zur vollständigen Trockenheit, erhitzt wurde. Auch das Eisenoxyd, welchen Ursprungs es auch ist, wird getrocknet und zerkleinert, worauf beide in feinem Zustande mit Hülfe passender Misch- und Siebmaschinen zusammengemischt werden, und zwar im Verhältnifs von 250 Theilen Chlornatrium zu 100 Theilen Eisenoxyd (Fe2 OSJ oder zu einem solchen Gewicht eines Stoffes, aus welchem das Eisenoxyd in der besagten Menge von 100 Theilen erhalten werden kann. Wenn die Ingredienzien gründlich mit einander vermischt sind, setzt man Wasser in genügender Menge zu, um die Mischung in Consistenz eines dünnen Teiges zu bringen, worauf man einen feinen Strom Schwefelsäure über die teigartige Masse fliefsen läfst, die in beständiger Bewegung erhalten werden mufs, bis der erforderliche Betrag an Säure hinzugefügt worden ist. Auf die oben genannten Mengenverhältnisse an Salz und Eisenoxyd nimmt man 225 Theile Schwefelsäure (H.2 S O11J. Die Säure verbindet sich mit dem Natrium des Chlornatriums und bildet schwefelsaures Natron (Na2SO4). Das Umrühren der Mischung während der Zusetzung der Säure ist deshalb empfehlenswerth, damit die vorzeitige Verdichtung der Masse verhindert wird. Hiernach giebt man die Mischung in Formen von. Holz, Eisen oder dergleichen, bringt dieselben in einen Ofen und erhitzt auf etwa 1000C, bis die Mischung fest geworden ist. Ist dieser Zustand erreicht, so steigert man die Temperatur auf 150 bis 1800C. und erhält sie in dieser Höhe, bis die Masse in den Formen gelb geworden ist; diese Farbe giebt die Bildung von Eisenchlorid zu erkennen. Das Material ist jetzt für den Markt fertig.The operation is carried out as follows: One takes sodium chloride and mixes it intimately with so much finely powdered iron oxide that the iron is sufficient to bind all the chlorine present in the sodium chloride and thereby produce iron chloride. Ordinary salt (evaporated salt) is used as sodium chloride, which has been heated until it is completely dry. The iron oxide, whatever its origin, is dried and crushed, after which both are mixed together in a fine state with the aid of suitable mixing and sieving machines, namely in the ratio of 250 parts sodium chloride to 100 parts iron oxide (Fe 2 O S J or to such a weight of a substance from which the iron oxide can be obtained in the said amount of 100 parts. When the ingredients are thoroughly mixed with one another, water is added in sufficient quantity to bring the mixture into the consistency of a thin dough, whereupon A fine stream of sulfuric acid is allowed to flow over the dough-like mass, which must be kept in constant motion until the required amount of acid has been added. 225 parts of sulfuric acid are added to the above proportions of salt and iron oxide (H. 2 SO 11 J. The acid combines with the sodium of the sodium chloride and forms sodium sulphate (Na 2 SO 4 ) It is therefore advisable to mix the mixture while the acid is being added to prevent premature compaction of the mass. The mixture is then poured into molds. Wood, iron or the like, place them in an oven and heat to about 100 ° C. until the mixture has solidified. Once this state has been reached, the temperature is increased to 150 to 180 ° C. and is maintained at this level until the mass in the molds has turned yellow; this color indicates the formation of ferric chloride. The material is now ready for the market.
Die zweite Erhitzung scheint die zuerst entstehende Verbindung (Na H S O4J in schwefelsaures Natron (Na2 S O4J zu verwandeln. Das letztere schliefst das Eisenchlorid in sich ein, und es bildet sich so eine Masse, die, der Feuchtigkeit ausgesetzt, nicht zergeht, wodurch ein das Eisenchlorid enthaltendes Product erzielt ist, welches einen sicheren, leichten Transport und eine bequeme Handhabung des Eisenchlorids beim Gebrauch ermöglicht.The second heating seems to transform the compound formed first (Na HSO 4 J into sulphate of soda (Na 2 SO 4 J. The latter locks the ferric chloride in itself, and a mass is formed which, when exposed to moisture, does not dissolve whereby a product containing the ferric chloride is achieved which enables safe, easy transportation and convenient handling of ferric chloride during use.
Das zu verwendende Eisenoxyd kann entweder das gewöhnliche Hämatiteisenerz, der Limonit oder Brauneisenstein, der calcinirte und gründlich oxydirte Spatheisenstein oder Eisencarbonat, der geröstete oder gebrannte Eisenpyrit etc. sein.The iron oxide to be used can either be the ordinary hematite iron ore, the Limonite or brown iron stone, the calcined and thoroughly oxidized late iron stone, or Iron carbonate, roasted or burnt iron pyrite etc.
Das Verfahren beschränkt sich nicht auf irgend ein genaues Mischungsverhältnifs, daThe method is not limited to any precise mixing ratio, as
man dasselbe bis zu einem gewissen Grade verändern kann, ohne ein wesentlich anderes Product zu erhalten oder die Eigenschaften desselben, sehr zu beeinflussen.one can change the same thing to a certain extent without an essentially different one To maintain the product or to greatly influence the properties of the same.
Als Beispiel folgt hier unten ein zweites Verhältnifs, von dem ich wahrgenommen habe, dafs es gute Resultate ergiebt, nämlich:As an example, below is a second relationship from which I have perceived that it gives good results, namely:
Chlornatrium 351 Theile,Sodium chloride 351 parts,
Eisenoxyd 160Iron oxide 160
Schwefelsäure 294Sulfuric acid 294
Wasser 200Water 200
Das Verfahren ist dasselbe, wie es oben beschrieben wurde. Das Product enthält Eisenchlorid in transportfähiger und solcher Form, die weit bequemer zu handhaben ist als die bisherigen Zubereitungen des Eisenchlorids, wie man sie bis jetzt zur Behandlung der Abwässer etc. zur Verwendung bringt.The procedure is the same as described above. The product contains ferric chloride In transportable and such a form that is far more convenient to handle than that previous preparations of iron chloride, as they have been used up to now for the treatment of waste water etc. brings to use.
Nach einer Modification des Processes benutzt man eine concentrirte Lösung von schwefelsaurem Natron (Na2 S O4 + ι ο H2 O) und giebt derselben einen Zusatz von mehr oder weniger concentrirter Eisenchloridlösung in angemessenem Verhältnifs, worauf das Ganze gründlich mit einander vermischt wird. Dann concentrirt man die Mischung bis zur Krystallisation des schwefelsauren Natrons und bringt sie in Formen oder zum Erstarren. Ist dies geschehen, so ist das Product handelsfertig.After a modification of the process, one uses a concentrated solution of sulphate of soda (Na 2 S O 4 + ι ο H 2 O), and gives it an addition of more or less concentrated ferric chloride solution in an appropriate proportion, whereupon the whole is thoroughly mixed with one another. The mixture is then concentrated until the sodium sulphate is crystallized, and shaped or solidified. Once this has been done, the product is ready for trading.
Zur Behandlung der Abwässer von Closets u. s. w. kann man Tafeln oder Blöcke des Products, das nach dem einen oder anderen Procefs hergestellt wurde, in das Ableitungsrohr bringen; das durchfliefsende Wasser löst die Tafel auf, wodurch das Eisenchlorid allmälig frei wird. Wenn es erforderlich ist, das Product in Form von Pulver anzuwenden, so können die Blöcke auch in gewünschtem Grade zerkleinert werden.For the treatment of the wastewater from closets and so on, panels or blocks of the Products manufactured according to one or the other process into the drainage pipe bring; the water flowing through it dissolves the table, gradually removing the ferric chloride becomes free. If it is necessary to use the product in powder form, then so the blocks can also be crushed to the desired degree.
