Description

Verfahren zur direkten Gewinnung von ölfreiem Paraffin. Zusatz zum Patent 369883. Gegenstand des Hauptpatents ist ein Verfahren zur direkten Gewinnung von ölfreiem Paraffin aus Urteer oder seiner Destillationsprodukte durch Behandlung mit einem Benzolalkoholgeniisch. Bereits in dem Hauptpatent ist angegeben, daß an Stelle des Benzols seine Homologen oder Flüssigkeiten mit ausgesprochenen guten Lösungsvermögen für 51e treten können.Process for the direct production of oil-free paraffin. Addition to Patent 369883. The main patent relates to a process for direct extraction of oil-free paraffin from primeval tar or its distillation products by treatment with a benzene alcohol genius. It is already stated in the main patent that an Place of benzene its homologues or liquids with decidedly good ones Solving power for 51e can occur.

Es hat sich nun herausgestellt, daß insbesondere die Verwendung gechlorter Kohlenwasserstoffe, wie beispielsweise Tetrachlorkohlenstoff u. dgl., mit Alkohol gemischt, vorteilhaft ist.It has now been found that in particular the use of chlorinated Hydrocarbons such as carbon tetrachloride and the like with alcohol mixed, is beneficial.

Die Benutzung gerade dieser Lösungsmittel hat den Vorteil, daß das Alkoholgemisch @vesentlich an Entzündbarkeit und Feuergefährlichkeit verliert.The use of these solvents has the advantage that the Alcohol mixture significantly loses its flammability and fire hazard.

Es wurde weiter gefunden; daß auch sauerstoffhaltige Körper, wie die alkalilöslichen Teersäuren, insbesondere die phenolartigen Bestandteile des Urteers, die in Alkohol löslich sind, mit Vorteil in Mischung mit Alkohol zur Abscheidung von Paraffin verwendet werden können. Diese Körper besitzen ein gutes Lösevermögen für die öligen, asphalt-und harzartigen Bestandteile der Teere bzw. ihrer Destillationsprodukte, gestatten also, daß das unter der Wirkung des Alkohols ausfallende Paraffin möglichst frei von dei genannten Beimengungen erhalten wird. Derartige Mischungen von Teersäuren und Alkohol können demnach mit Vorteil gerade für weniger reine Ausgangsmaterialien verwendet werden.It was found further; that also oxygen-containing bodies, like that alkali-soluble tar acids, especially the phenol-like constituents of the primordial tar, which are soluble in alcohol, advantageously mixed with alcohol for separation of paraffin can be used. These bodies have good solvent power for the oily, asphalt and resinous components of the tars or their distillation products, So allow the paraffin precipitating out under the action of the alcohol as much as possible is obtained free of the mentioned admixtures. Such mixtures of tar acids and alcohol can therefore be used to advantage, especially for less pure starting materials be used.
