Verfahren zur Trennung der festen Paraffin-Kohlenwasserstoffe von den flüssigen
Beimengungen.
EMI1.1
<Desc/Clms Page number 2>
Fraktion eine Lösung von aromatischen Kohlenwasserstoffen in schwefliger Säure solange hinzufügt, bis die Abscheidung der festen Paraffinkohlenwasserstoffe erfolgt. Man kann als Ausgangsmaterial entweder unmittelbar die betreffende, das Paraffin enthaltende Fraktion des Erdöldestillates nehmen, oder aus dieser vorerst einen Teil der flüssigen Paraffine durch die bereits bekannten Methoden beseitigen. Nachdem die Abscheidung eingetreten ist, wird filtriert, gepresst und der Niederschlag mit flüssiger schwefliger Saure nachgewaschen.
Ats aromatische Kohlenwasserstoffe kann in diesem Falle der Extrakt benutzt werden, den man nach dem Verfahren der Patentschrift Nr. 44088 bei der Reinigung des Erdöls
EMI2.1
Beispiel lässt sich auch das Paraffin aus dem Schieferöl abscheiden
Die Konzentration der Lösung der flüssigen schwefligen Säure in aromatischen Kohlenwasserstoffen, die in den einzelnen Fällen zur Verwendung gelangt, richtet sich nach dem zu behandelnden Rohmaterial. Das Wesen der Erfindung bleibt aber in allen Flllen das gleiche : die Abscheidung der festen Paraffin-Kohlenwasserstoffe aus dem vorhandenen Gemisch vermittels einer Lösung von aromatischen bzw. zyklischen ungesättigten Kohlenwasserstoffen in flüssiger schwefliger Säure.
Folgende besondere Beispiele mögen die Ausführung des Verfahrens noch naher erläutern.
100 Teile aus Braunkohlenteer gewonnenen Paraffinöls werden in einem geeigneten Gefäss mit 70 bis 100 Teilen flüssiger schwefliger Säure bei gewöhnlicher Temperatur versetzt.
Es scheidet sich das Paraffin in Form kristallinischer Schuppen ab. Man saugt hierauf ab und wäscht den Rückstand ein-bis zweimal mit flüssiger schwefliger Säure nach. Auf
EMI2.2
gleichen Menge eines Gemisches aromatischer Kohlenwasserstoffe, wie sie nach dem Verfahren der Patentschrift Nr. 44u88 gewonnen werden, verdünnt und hleranf mit 100 Teilen flüssiger schwefliger Säure versetzt. Die Abscheldung des Paraffins beginnt sofort, die Woiterverarbeitung erfolgt wie im Beispiel I angegeben. Zum Nachwaschen kann in diesem Falle zunächst an Stelle von reiner schwefliger flüssiger Säure in den bezeichneten aromatischen Kohlenwasserstoffen benutzt werden.

Process for separating the solid paraffin hydrocarbons from the liquid ones
Admixtures.
EMI1.1
<Desc / Clms Page number 2>
Fraction adds a solution of aromatic hydrocarbons in sulphurous acid until the solid paraffinic hydrocarbons are separated. The starting material can either be taken directly from the paraffin-containing fraction of the petroleum distillate in question, or a part of the liquid paraffins can be removed from it by the methods already known. After the separation has occurred, it is filtered, pressed and the precipitate is washed with liquid sulphurous acid.
The aromatic hydrocarbons which can be used in this case are the extract obtained by the process of patent specification No. 44088 in the purification of petroleum
EMI2.1
For example, the paraffin can also be separated from the shale oil
The concentration of the solution of liquid sulfurous acid in aromatic hydrocarbons which is used in the individual cases depends on the raw material to be treated. The essence of the invention remains the same in all cases: the separation of the solid paraffin hydrocarbons from the existing mixture by means of a solution of aromatic or cyclic unsaturated hydrocarbons in liquid sulfurous acid.
The following special examples may explain the implementation of the method in more detail.
100 parts of paraffin oil obtained from lignite tar are mixed with 70 to 100 parts of liquid sulphurous acid at ordinary temperature in a suitable vessel.
The paraffin separates out in the form of crystalline flakes. It is then filtered off with suction and the residue is washed once or twice with liquid sulfurous acid. On
EMI2.2
the same amount of a mixture of aromatic hydrocarbons as obtained by the process of patent specification No. 44/88, diluted and then mixed with 100 parts of liquid sulphurous acid. The separation of the paraffin begins immediately, the word processing takes place as indicated in Example I. In this case, pure sulphurous liquid acid can be used for rewashing in the aromatic hydrocarbons indicated.
