Description

Verfahren zur Entfernunfvon Harz, Fett, Wachs u. dgl. aus Pflanzenstoffen, insbesondere aus Holz und Holzzellstoffen.Process for removing resin, fat, wax and the like from plant matter, in particular made of wood and wood pulp.

Zusatz zum Patent 363666. Beider Ausführung des Verfahrens zur Entfernung von Harz, Fett, Wachs u. dgl. aus Pflanzenstoffen, insbesondere aus Holz und Hotzzellstoffen nach Patent 363666 wurde nun gefunden, daß es zweckmäßig ist, zur Bereitung der Lauge Luft- bzw. sau.erstoffreies Wasser zu nehmen und die Extraktion unter völligem oder doch -möglichst beschränktem Luftzutritt: vorzunehmen.Addendum to Patent 363666. When performing the removal process of resin, fat, wax and the like from plant materials, in particular from wood and hot cellulose according to patent 363666 it has now been found that it is useful to prepare the Lye to take air or oxygen-free water and the extraction under complete or at least - as restricted air access as possible: to be carried out.

Die Luft oder vielmehr der Sauerstoff der Luft vermag nämlich; wie .gefunden wurde, die Harze, g eg ebenfalls auch das Terpentin, in ihren Lösungen oder Emulsionen zu beeinflussen. Durch Luftoxydation können diese Körper schwer bzw. unlöslich in alkalischer und organischer Flüssig geit, ja sogar organische Lösungsmittel werden. Es empfiehlt sich daher die Fernhaltung von Sauerstoff, die hei den Extraktflüssigkeiten in einfachster Weise durch Sauerstoff verzehren1e Zusätze, wie Natriumsulfit, Natriumhydrosulfit, geschehen kann.The air, or rather the oxygen in the air, is capable of; how The resins, including turpentine, were found in their solutions or to influence emulsions. These bodies can become heavy due to air oxidation or insoluble in alkaline and organic liquids, even organic ones Solvent. It is therefore advisable to keep away from oxygen in the case of extract fluids, additives that are consumed in the simplest way by means of oxygen, such as sodium sulfite, sodium hydrosulfite, can happen.

Durch passende Bauart der Apparate kann man auch. die Berührung der Flüssigkeit oder des Holzes u. dgl. mit Luft sehr einschränken, ja ganz vermeiden. Willman die Extraktion i,m Schaum vornehmen, so kann zur Erzeugung des Schaumes ein indifferentes Gas oder Sauerstoff nicht enthaltendes Gasgemenge, z. B. Stickstoffgas, angewendet werden.You can also use the appropriate design of the apparatus. the touch of the Restrict liquid or wood and the like with air very much, even avoid it completely. If one wants to extract the foam, it can produce the foam an inert gas or a gas mixture not containing oxygen, e.g. B. nitrogen gas, be applied.
