Description

Verfahren zur Trennung von Phosphor und Arsen. Gegenstand der Erfindung bildet ein Verfahren zur Trennung von rotem Phosphor und metallischem Arsen auf mechanischem Wege. Gemische von etwa gleichen Teilen Phosphor und Arsen mit einem Zusatz von etwa zo Prozent organischen Körpern, wie Paraffin, Montanwachs u. dgl., die sogenannten Unterkörper von Granaten, sind aus der Kriegswirtschaft in großen Mengen vorhanden und können durch vorliegendes Verfahren der Erfindung wirtschaftlich nutzbringend verwertet werden.Process for separating phosphorus and arsenic. Subject of the invention sets up a process for separating red phosphorus and metallic arsenic mechanical way. Mixtures of approximately equal parts of phosphorus and arsenic with one Addition of about zo percent organic bodies, such as paraffin, montan wax, etc., The so-called lower bodies of grenades, are from the war economy in large Amounts are present and can be made economical by the present process of the invention can be used profitably.

Es sind verschiedene Verfahren vorgeschlagen worden, um durch chemische Behandlung - Oxydation oder Chlorierung - diese Unterkörper in ihre Bestandteile -zu zerlegen. Abgesehen davon, daß auf chemischem `Fege meist nur die Trennung durch Bildung von Verbindungen des Phosphors oder Arsens möglich ist, haben sie bisher nicht zu einem befriedigenden Ergebnis geführt.Various methods have been proposed to get through chemical Treatment - oxidation or chlorination - these sub-bodies into their constituent parts -disassemble. Apart from the fact that on chemical sweeping mostly only the separation by Formation of compounds of phosphorus or arsenic is possible, they have so far did not lead to a satisfactory result.

Es wurde nun gefunden, daß man durch naßmechanische Aufbereitung der vorher von Wachs oder Paraffin befreiten Unterkörper eine glatte Trennung des Gemisches in Phosphor und Arsen erzielen kann. Das Verfahren gestattet also, mittels einfacher Maßnahmen ohne Verwendung von Chemikalien die Herstellung von technisch reinem, verkaufsfähigem Phosphor und Arsen.It has now been found that by wet mechanical processing of the Lower body previously freed from wax or paraffin ensures a smooth separation of the mixture in phosphorus and arsenic. The method thus allows, by means of a simple Measures without the use of chemicals the production of technically pure, salable phosphorus and arsenic.

Das Verfahren wird wie folgt ausgeübt Die enthülsten Unterkörper werden mit einer geeigneten Lösung, z.B. Trichloräthylen, extrahiert und der Rückstand mit Wasser angerührt. Das angerührte Gut wird alsdann durch eine Mischvorrichtung hindurch in den Verteilungskasten eines Stoßherdes gebracht, der es mehr oder weniger nach den verschiedenartigen Bestandteilen getrennt in verschiedene Behälter bringt. Schon nach dem ersten Gange erhält man in einem Behälter einen fast arsenfreien Phosphor und in einem anderen Behälter einen in der Hauptsache nur aus Arsen bestehenden Rückstand, während andere Behälter angereicherte Gemische enthalten; zur vollkommenen Befreiung des Schlammes von Phosphor läßt man die Produkte dieses ersten Ganges den Stoßherd wiederholt passieren.The procedure is practiced as follows The hulled lower body will be performed with a suitable solution, e.g. trichlorethylene, extracted and the residue mixed with water. The mixed material is then mixed through a mixer brought through it into the distribution box of a shock cooker, which it more or less according to the different components separately in different containers. Already after the first course you get an almost arsenic-free in a container Phosphorus and, in another container, one consisting mainly of arsenic Residue while other containers contain enriched mixtures; to the perfect The products of this first course are allowed to clear the sludge of phosphorus repeatedly pass the shock focus.
