Description

Verfahren zur Gewinnung von Schwermetallen aus sie enthaltenden Lösungen Bei vielen, namentlich katalytischen Verfahren ent- halten die entstehenden Endstoffe z. 13. aus den Kata- lysatoren stammende geringe Beimengungen von Metallen, meistens in Form der Metallverbindungen, z. B. Mangan, Kobalt, Nickel, Kupfer, Silber, Molyb- dän, Wolfram, Thorium, Vanadium usw. Es ist sehr erwünscht, diese Metalle aus den 1?ndstoffen oder den Waschwässern zurückzugewinnen. Es wurde gefunden, da13 man diese Aufgabe selbst hei Lösungen, die mir ganz geringe, unter z" " liegende Mengen der yletalle enthalten, in technisch befriedi- gencIcr Weise derart lösch kann, daß nran die Metalle aus den sie enthaltenden Lösungen in Form ihrer Salze mit höhermolekularen, nicht aromatischen Carbonsäuren ausfällt und diese abtrennt. Ein Gehalt der Lösungen an Leichtmetallsalzen, z. B. Alkalichlorid, -nitrat oder -sulfat, stört dabei nicht.Process for the extraction of heavy metals from solutions containing them In many processes, namely catalytic keep the resulting end products z. 13. from the catalog small additions of Metals, mostly in the form of metal compounds, z. B. manganese, cobalt, nickel, copper, silver, molyb- Danish, tungsten, thorium, vanadium, etc. It's very Desirably, these metals from the primary substances or the Recover washing water. It has been found that you can do this yourself Hei solutions that give me very little, under z "" lying Quantities of the oil all contain, in technically satisfactory In general, it can extinguish it in such a way that only the metals precipitates from the solutions containing them in the form of their salts with higher molecular weight, non-aromatic carboxylic acids and separates them. A content of the solutions of light metal salts, e.g. B. alkali chloride, nitrate or sulfate does not interfere.

zur Ausfällung der Metalle wendet man am einfachsten Lösungen von Alkalisalzen der Carbonsäuren an, z. 13. von Stearinsäure oder Palmitinsäure ()der Gemischen derartiger Säuren, wie sie z. B. auch in synthetischen Fettsäuren vorliege, die ;ins der Oxydation von Paraffin u. dgl. stammen. Sehr gut eignen sieh auch wasser-lüsliche Salze von Naphthensäuren. Im allgemeinen kommen Carbonsäuren der genannten Art mit einem Molekulargewicht von zweckmäßig über 170 in Betracht. Es empfiehlt sich, die Ausfällung bei nicht zu hoher Temperatur vorzunehmen, damit die organischen :Metallsalze in flockigem, leicht filtrierbarem Zustand entstehen. Sie lassen sich in manchen Fällen unmittelbar wieder für katalytische Verfahren anwenden, z. B. Mangansalze bei der Oxydation von Paraffin. Man kann sie aber auch mit Mineralsäuren spalten und so die Fettsäure und die entsprechende :Metallverbindung in leicht verwertbarer Form gewinnen. Beispiel an löst iooo Teile einer rohen Seife, erhalten durch 3 Oxydation von Paraffin in Gegenwart von Kaliumpermanganat, Verseifen mit Natronlauge und Abtrennen der unverseifbaren Anteile, in 25oo Teilen wäßriger Natriumsulfatlösung und spaltet sie bei 8o° mit 3oo Teilen konzentrierter Schwefelsäure. Die sich abscheidende wäßrige Natriumsulfatlösung enthält nach dem Abtrennen des ausgeschiedenen Natriumsulfats den Mangankatalysator als Mangansulfat in einer Menge von wesentlich weniger als Die Lösung wird zunächst mit einem Gemisch von Butanon und Benzol ausgezogen und dann mit wenig Natronlauge neutralisiert. Hierauf gibt man eine Lösung von 6 Teilen der Natronseife von Paraffinfettsäure in ioo Teilen `'Wasser zu. Der sich abscheidende \iederschlag wird abfiltriert. Er enthält das gesamte in der Rohseife vorhanden gewesene Mangan als Manganseife. Diese kann entweder als solche zu katalytischen Zwecken verwendet @ oder mit Mineralsäure zerlegt werden.the simplest way to precipitate the metals is to use solutions of alkali metal salts of carboxylic acids, e.g. 13. of stearic acid or palmitic acid () of the mixtures of such acids, as z. B. also exist in synthetic fatty acids, which come from the oxidation of paraffin and the like. The water-soluble salts of naphthenic acids are also very suitable. In general, carboxylic acids of the type mentioned with a molecular weight expediently above 170 are suitable. It is advisable to carry out the precipitation at a temperature that is not too high so that the organic: metal salts are formed in a flaky, easily filterable state. In some cases they can be used again immediately for catalytic processes, e.g. B. Manganese salts in the oxidation of paraffin. But you can also split them with mineral acids and thus obtain the fatty acid and the corresponding metal compound in an easily usable form. Example dissolves at iooo parts of a crude soap obtained by oxidation of paraffin 3 in the presence of potassium permanganate, saponification with sodium hydroxide solution and separation of the unsaponifiable components, in aqueous 25oo parts of sodium sulfate solution and splits them at 8o ° with 3oo parts of concentrated sulfuric acid. The aqueous sodium sulphate solution which separates out contains, after the separated sodium sulphate has been separated off, the manganese catalyst as manganese sulphate in an amount much less than. The solution is first extracted with a mixture of butanone and benzene and then neutralized with a little sodium hydroxide solution. A solution of 6 parts of the sodium soap of paraffin fatty acid in 100 parts of water is then added. The precipitate that separates out is filtered off. It contains all the manganese that was present in the raw soap as manganese soap. This can either be used as such for catalytic purposes @ or broken down with mineral acid.
