Description
Verfahren zum Raffinieren von Wlineralölen. In dem Patent 374928 wird ein Verfahren beschrieben zur Reinigung von Kohlenwasserstoffen mit Alkalien in der Wärme. In der weiteren Ausarbeitung dieser Arbeitsweise hat sich gezeigt, daß die Reinigung noch leichter bei Behandlung mit Amalgamen vor sich geht, und zwar führen dabei niedrigere Temperaturen schon zum Ziele; man kann sogar bei gewöhnlicher Temperatur arbeiten, allerdings muß dann die Dauer der Einwirkung ziemlich ausgedehnt werden. Es ist auch nicht unbedingt erforderlich, das Amalgam in fertigem Zustande zuzusetzen, sondern man kann z. B. bei Wasserbadtemperatur metallisches Natrium und etwas Quecksilber zugeben, die Vereinigung zu Natriumamalgam erfolgt dann häufig unter Zischen. Das Quecksilber kann immer wieder benutzt werden.Process for refining wliner oils. The patent 374928 describes a method for cleaning hydrocarbons with alkalis in the heat. In the further elaboration of this procedure it has been shown that cleaning is even easier when treated with amalgams, and that lower temperatures already lead to the goal; one can even work at ordinary temperature, but then the duration of the action must be extended quite a bit. It is also not absolutely necessary to add the amalgam in the finished state, but you can, for. B. add metallic sodium and a little mercury at water bath temperature, the combination to sodium amalgam then often takes place with hissing. The mercury can be used over and over again.
Bei dem vorliegenden Verfahren beruht die reinigende Wirkung kaum auf der bekannten Reduktionswirkung des Natriumamalgarns, sondern auf der Ausfällung asphaltartiger Stoffe durch das Natriw-n, das durch die Verbindung oder Anwesenheit von Quecksilber in seiner Reaktionsfähigkeit erhöht wird. Unter Umständen ermöglicht die Quecksilber--verbindung des Natriums überhaupt erst die volle Ausnutzung des Natriums, z. B. beim Arbeiten in der Kälte. Läßt man nämlich metallisches Natrium auf Mineralöle bei gewöhnlicher Temperatur einwirken, so überzieht sich das Natrium sehr schnell mit einer Schicht, die es an -weiterer Einwirkung verhindert, dadurch wird aber das Verfahren unwirtschaftlich.In the present process, the cleaning effect is hardly based on the well-known reducing effect of the sodium amalgarn, but on the precipitation asphalt-like substances by the Natriw-n, that by the connection or presence mercury increases its reactivity. May be possible The mercury compound of sodium is what makes full use of the sodium in the first place Sodium, e.g. B. when working in the cold. Namely, if you leave metallic sodium If mineral oils act at ordinary temperature, the sodium is coated very quickly with a layer that prevents it from further exposure but the process becomes uneconomical.
Beispiel i.Example i.
io-kg galizische Schmierölfraktion wurde mit 500 9 4prozentigem Natriumamalgani auf ioo' erwärmt; sodann wurden 300 9 Natrium in kleinen Teilmengen zugegeben und das Ganze :24 Stunden unter öfterem Umrühren bei der Temperatur von iool gehalten. Nach Abkühlen und längerem Stehen wurde abfiltriert.10 kg of Galician lubricating oil fraction was heated to 100% with 500 9 4 per cent sodium amalgani; 300 g sodium were then added in small portions and the whole thing was kept at the temperature of iool for 24 hours with frequent stirring. After cooling and prolonged standing, it was filtered off.
Beispiel 2. Benzinfraktion aus Erdöl wird mit etwas 4prozentigem Natriumamalgam unter öfteren Umrühren einige Tage bei gewöhnlicher Temperatur stehengelassen. Hierauf filtriert man vom überschüssiigen Amalgam und dunkelgrauen Niederschlag ab.Example 2. Gasoline fraction from petroleum is mixed with some 4% sodium amalgam left to stand for a few days at normal temperature, stirring frequently. On that the excess amalgam and dark gray precipitate are filtered off.
