Description

Verfahren zur Destillation von Rohmontanwachs Bei der Destillation von Rohmontanwachs erhält man, selbst bei Verwendung von entharztem Wachs, unreine gefärbte Destillate. Sie sehen meist braun bis schii--ti'czi`grün aus und lassen sich äußerst schwer raffinieren. Zur Erzielung reiner Produkte hat man bereits vorgeschlagen, das Rohmontanwachs zu destillieren und das erhaltene Destillat durch Buliandlun'g mit Entfärbungspulver zu reini-;;Cn. Die bei der Destillation des Montan-IVachses übergehenden Verunreinigungen werdUn jedoch von dein Destillat so stark festgehalten, claß sie nur schwer und unter großem Aufwand vom Entfärbungspulver entfernt «-erden können.Process for the distillation of raw montan wax. During distillation from raw montan wax you get impure, even when using wax that has been removed from the resin colored distillates. They usually look brown to schii - ti'czi` green and leave extremely difficult to refine. In order to obtain pure products, it has already been proposed that to distill the raw montan wax and the resulting distillate by Buliandlun'g with decolorizing powder to pure - ;; Cn. The one in the distillation of the Montan-Iachs However, passing impurities are retained so strongly by your distillate that remove them from the decolorizing powder only with great difficulty and with great effort can.

Es wurde nun gefunden, flaß diese Sch-,vierigkeiten beseitigt find helle, reine Destillate aus Rohniontanwachs leicht dadurch erli.aten werrlen können, daß man die Destillation in Gegenwart von absorbierend wirkenden Stoffen, z. B. aktiver Kohle, Bleicherde, Tonscherben, Bimsstein, Kieseisätire und ähnlichen Substanzen, durchfiihrt.It has now been found that these inconveniences have been eliminated light, pure distillates from Rohniontan wax can easily be obtained in this way, that the distillation in the presence of absorbing substances such. B. active coal, fuller's earth, pottery shards, pumice stone, gravel and similar substances, carried out.

Das Verfahren kann in der Weise ausgeübt werden, daß inaii das Absorptionsmittel, z. B. akliv@, Kohle. den] Wachs vor ler Destillation zusetzt. Eine besonders günstige Wirkung wird erzielt, wenn man das Wachs in Dampfform während @ler Destillation durch ein Svstein von absorbierend wirkenden Stoffen führt. 1ltin kann die Absorptionsvorrichtung, die z. B. Zylinderform besitzen kann, auf die Destillationsblase unmittelbar aufsetzen, so daß der Destillatdampf durch sie hindurchstreichen muß, bevor er gekühlt wird und sich kondensiert; man kann aber auch Kammern oder Kolonnen, die auf die Destillationstemperatur geheizt sind, an den Abzug der Destillationsblase anschließen. Zweckmäßig belädt man die Kammern oder Kolonnen mit verschiedenartigen Absorptionsstoffen; man kann sie in Mischung verwenden oder durch Siebeinlagen voneinander getrennt halten. Ptilverförniige Stoffe, wie Kohle oder Bleicherde, können vorher auch granuliert werden.The method can be practiced in such a way that inaii the absorbent, z. B. akliv @, coal. the] wax is added before the distillation. A particularly cheap one Effect is achieved if the wax is used in vapor form during distillation leads through a chain of absorbent substances. 1ltin can the absorption device, the z. B. can have a cylindrical shape, put directly on the still, so that the distillate vapor must pass through them before it is cooled and condenses; but you can also chambers or columns that are set to the distillation temperature are heated, connect to the vent of the still. Appropriately loaded the chambers or columns with various types of absorption material; one can use them in a mixture or keep them separated from each other with sieve inserts. Ptilverförniige Substances such as coal or fuller's earth can also be granulated beforehand.

Da-Verfahren läßt sich sowohl hei @ler gewöhnlichen Destillation als auch bei der Vakuum- und Wasserdampfdestillation verwenden.The Da process can be used both as a conventional distillation and as a also use for vacuum and steam distillation.

Besondere Vorteile zeigen sich bei der Destillation in Gegenwart von Gasen, u-obei es ohne Bedeutung ist, ob diese nur zui- Bleic-h.ttng oder zur weitgehenderen chemischen Veränderung des Wachses verwendet werden. So kann z. B. in Gegenwart von Schwefeldio--"yd, Sauerstoff oder Luft oder Wasserstoff gearbeitet werden, wobei #lie große Oberfläche der Absorptionsstotie eine inechanisch und katalytisch unterstützende Wir-kung ausübt.Particular advantages are found in the distillation in the presence of gases, regardless of whether these are used only for lead or for a more extensive chemical change in the wax. So z. B. in the presence of Schwefeldio - be worked or air or hydrogen "yd, oxygen, wherein #lie large surface of the Absorptionsstotie exerts a inechanisch and catalytically supporting WIR effect.

Der Vorteil des vorliegenden Verfahrens gegenüber den bisherigen Arbeitsweisen besteht in der vollständigen Entfernung der Verunreinigungen bei verhältnismäßig geringem Aufwand an Absörptionsmittel. Außerdem ist die Ausbeute an wertvollem gereinigtem Wachs erheblich höher als bei den bekannten Verfahren, indem nach vorliegendem Verfahren das reine Destillat ohne weiteres in voller Ausbeute gewonnen wird.The advantage of the present procedure opposite to the previous working methods consisted in the complete removal of the impurities with a relatively low expenditure of absorbent. Besides, the yield is significantly higher in valuable cleaned wax than with the known processes, by using the present process, the pure distillate readily in full yield is won.
