Description

Verfahren zur Extraktion von Rohharz u. dgl. Es ist bekannt, daß bei. der Extraktion verschiedenster Körper Kohlenwasserstoffe wie auch Chlorderivate von Kohlenwasserstoffen in Mischungen mit Äthylalkohol als Lösungsmittel verwandt werden und daß das Lösungsverfahren wie der Verlauf des Arbeitsprozesses mit derartigen Lösungsmitteln sehr verschieden ist. Äthylalkohol in Verbindung mit Kohlenwasserstoffen, wie den Chlorderivaten von @ Kohlenwasserstoffen, hat bei der Extraktion wasserhaltiger Körper die unangenehme Eigenschaft, durch das Wasser leicht seine Lösefähigkeit zu verlieren; es sind dafür so große Mengen von Äthylalkohol erforderlich, um die tbelstände zu beseitigen, daß die Mischung anzuwenden praktisch zur Unmöglichkeit wird, z. B. bei der Extraktion von Rohharzen, Schlacken aus Rohharzen bei wasserhaltigen Bleicherden u. dgl. Der Alkohol wird, sofern die zu extrahierenden Körper nur 15 bis *-o Prozent Wasser enthalten, sehr leicht auf 6o bis 65 Volumprozent Alkohol verdünnt, und schon in diesem Stadium entmischt sich die Lösung von Alkohol in Kohlenwasserstoffen und deren Derivaten in eine wässerige alkoholische Schicht, die keine Lösungsfähigkeiten mehr besitzt, und eine Kohlenwasserstoffschicht, die so wenig Alkohol enthält, daß die beabsichtigte Verbesserung der Lösungsfähigkeit praktisch bedeutungslos wird.Process for extracting raw resin and the like. the extraction of various body hydrocarbons as well as chlorine derivatives of hydrocarbons in mixtures with ethyl alcohol as a solvent and that the solution method as the course of the work process with such Solvents is very different. Ethyl alcohol in connection with hydrocarbons, like the chlorine derivatives of @ hydrocarbons, has water-containing in the extraction Body's unpleasant property, because of the water easily its solvability to lose; it takes so large amounts of ethyl alcohol to get the Eliminate dirt that the mixture to apply practically impossible will, e.g. B. in the extraction of raw resins, slag from raw resins in the case of hydrous Bleaching earth and the like. The alcohol is, if the body to be extracted is only 15 Contains up to * -o percent water, very slightly to 6o to 65 percent alcohol by volume diluted, and already at this stage the solution of alcohol in hydrocarbons separates and their derivatives in an aqueous alcoholic layer that has no solubility has more, and a hydrocarbon layer that contains so little alcohol that the intended improvement in solvability becomes practically insignificant.

Es ist auch bekannt, daß bei der Herstellung der Fuselöllacke das Fuselöl die Lösungseigenschaften der Kohlenwasserstoffe wie deren Derivate in ähnlicher Weise verbessert wie Äthyl- und Methylalkohol. Festgestellt wurde, was keineswegs ohne weiteres zu erwarten war, daß bei Hinzutritt von Wassermischungen der gedachten Art keine wesentliche Änderung der Lösung eintritt. Es bildet sich zwar auch hier wieder eine wässerige alkoholische Schicht, aber nur in sehr beschränktem Umfang, so daß die Hauptmenge des Amylalkohols und ähnlicher Alkohole unverändert beim Lösungsmittel verbleibt und seine Lösefähigkeit aufrechterhält.It is also known that in the manufacture of fusel oil varnishes Fusel oil has similar properties of the hydrocarbons as their derivatives Way improved like ethyl and methyl alcohol. What was determined by no means it was to be expected without further ado that the intended Art no significant change in the solution occurs. It is also formed here again a watery alcoholic layer, but only to a very limited extent, so that most of the amyl alcohol and similar alcohols remain unchanged in the solvent remains and maintains its solvency.
