Description
Herstellung von Alkallphosphat und Wasserstoff Es wurde gefunden, daß man Schwermetallphosphide, insbesondere Ferrophosphor, in Alkaliphosphat und das betreffende Schwermetalloxyd bzw. -carbonat überführen kann, wenn man sie mit wäßrigen Lösungen von Ätzalkalien oder Alkalicarbonaten beliebiger Konzentration unter erhöhtem Druck bei Temperaturen über roo° behandelt.Production of alkali phosphate and hydrogen It was found that you heavy metal phosphides, especially ferrophosphorus, in alkali phosphate and the heavy metal oxide or carbonate in question can be transferred if you use them with aqueous solutions of caustic alkalis or alkali carbonates of any concentration treated under increased pressure at temperatures above roo °.
Als wertvolles Nebenprodukt erhält man hierbei sehr reinen Wasserstoff unter erhöhtem Druck, der infolgedessen ohne weitere Nachbehandlung für Druckreaktionen, speziell zur Ammoniakdarstellung oder zu Hydrierungen aller Art verwendet werden kann. Das gebildete Alkaliphosphat wird aus dem erhaltenen Brei mit Wasser ausgelaugt und die Lösung beliebig weiterverarbeitet. Sie enthält höchstens Spuren von Eisen.Very pure hydrogen is obtained as a valuable by-product under increased pressure, which as a result, without further post-treatment for pressure reactions, can be used specifically for the preparation of ammonia or for hydrogenation of all kinds can. The alkali metal phosphate formed is leached from the resulting slurry with water and the solution can be processed further. It contains at most traces of iron.
Das Verfahren läßt sich besonders vorteilhaft mit dem bei der Herstellung von Phosphor aus Rohphosphat, Sand und Kohle im elektrischen oder Schmelzofen anfallenden Ferrophosphor durchführen. Der bei der Verwendung von Ferrophosphor größtenteils aus Eisenoxyd bzw. Eisencarbonat bestehende Rückstand kann zu den verschiedensten Zwecken verwendet werden, z. B. als Reinigungsmasse, zur Entfernung von Schwefel oder Phosphor bzw. deren Verbindungen aus Gasen, oder er kann zu Eisenschwamm reduziert werden. Das Verfahren kann diskontinuierlich in stehenden oder liegenden Autoklaven, die zweckmäßig eine Vorrichtung zum Durchmischen der Reaktionsteilnehmer aufweisen, durchgeführt werden. Es kann aber auch kontinuierlich gearbeitet werden, indem man in ein stehendes oder liegendes zylindrisches Hochdruckgefäß auf der einen Seite Ferrophosphor und Alkalilauge oder Alkalicarbonatlösung getrennt oder gemischt als Paste oder Emulsion geeigneter Konsistenz einführt und auf der anderen Seite die Umsetzungsprodukte abzieht. Dieses Hochdruckgefäß kann wieder mit einer Durchmischungsvorrichtung versehen sein, z .B. einer Schnecke, die zugleich die Umsetzungsstoffe zwangsläufig allmählich durch die Apparatur befördert.The method can be particularly advantageous with that in the manufacture of phosphorus from rock phosphate, sand and coal in electric or smelting furnaces Perform ferrophosphorus. Most of the time when using ferrophosphorus Residues consisting of iron oxide or iron carbonate can become very diverse Purposes are used, e.g. B. as a cleaning compound to remove sulfur or phosphorus or its compounds from gases, or it can be reduced to sponge iron will. The process can be carried out discontinuously in standing or lying autoclaves, which expediently have a device for mixing the reactants, be performed. But it can also be worked continuously by into a standing or lying cylindrical high pressure vessel on one side Ferrophosphorus and alkali lye or alkali carbonate solution separately or mixed as Paste or emulsion of suitable consistency and on the other hand the Deducts conversion products. This high pressure vessel can again with a mixing device be provided, e.g. a snail, which at the same time inevitably contains the reaction substances gradually conveyed through the apparatus.
