EMI2.1 Gewinnung von Aceton, Holzgeist usw. Soll eine Ablauge des in Rede stehenden Kochens nach dem Verfahren der trockenen Destillation regeneriert werden, so hat man auf folgende Weise zu verfahren : Wenn das verwendete Rohmaterial 20% Harz und 5% Terpentin enthält, so benutzt man beim Kochen zweckmässig 650 g Na2 O pro kg wasserfreien Holzes. Nach dem Kochen werden zur Ablauge etwa 200 9 cas pro kg trockenen Holzes in der Form von dicker Kalkmilch zugesetzt, worauf die Mischung eingedampft und unter Einwirkung von Wasserdampf in sogenannten Schichtöfen trocken destilliert wird. In diese wird die möglichst konzen- trierte Lauge auf Blechen mit einer Schichtstärke von etwa 4 cm eingeführt. Bei der trockenen EMI2.2 gegen die wärmeren hin geleitet. EMI2.1 Extraction of acetone, wood spirit, etc. If a waste liquor from the boiling in question is to be regenerated using the dry distillation method, the following procedure must be followed: If the raw material used contains 20% resin and 5% turpentine, it is advisable to use 650 g Na2 O per kg of anhydrous wood for cooking. After boiling, about 200 9 cas per kg of dry wood are added to the waste liquor in the form of thick milk of lime, whereupon the mixture is evaporated and dry distilled under the action of steam in so-called layer ovens. The lye, which is as concentrated as possible, is introduced into this on sheets with a layer thickness of around 4 cm. When dry EMI2.2 directed against the warmer ones. Zu diesem Zwecke kann vorteilhaft ein gewöhnlicher Holz- kohlungsofen veiwendet weiden, auf dessen Wagen die Bleche in geeignet en Zwischenräumen angebracht werden, wobei man dafür sorgt, dass der Wasserdampf Gelegenheit hat, die Flächen jedes Bleches möglichst regelmässig zu bestreichen. For this purpose, an ordinary charcoal furnace can be used, on whose trolley the sheets are placed in suitable spaces, making sure that the water vapor has the opportunity to coat the surfaces of each sheet as regularly as possible. Da die eingedickte Lauge beim Eintrocknen nicht zähe wird, so kann sie auch in einem rotierenden Ofen oder in einem Rührwerkskessel zu einer trockenen, aus kleineren Stücken bestehenden Masse eingetrocknet werden. So eingetrocknet, lässt sich die Masse leichter trocken destillieren, veil sie dabei nicht schmilzt. Die Masse kann daher in den Destillationsofen in wage. rechten oder senkrechten Schichten von bedeutend grösseren Stärke als 4 cm eingeführt werden. Since the thickened lye does not become viscous when it dries, it can also be dried in a rotating oven or in a stirrer vessel to a dry mass consisting of smaller pieces. Once dried in this way, the mass is easier to distill dry because it does not melt. The mass can therefore in the distillation furnace in dare. right or vertical layers significantly greater than 4 cm thick are introduced. Wenn zum Eintrocknen ein rotierender Ofen verwendet wird, wird dieser am besten direkt mittels warmer, am besten kohlensäurefreier Luft erhitzt. If a rotating oven is used for drying, it is best to heat it directly using warm, preferably non-carbonated, air. Das durch das oben beschriebene Verfahren erhaltene Rohharz ist von dunkler Farbe. The raw resin obtained by the method described above is dark in color. Aus ihm kann farbloses Harz durch Destillation hergestellt werden, die dabei am besten mittels Wasserdampf und im Vakuum ausgefüllt wird. Das Harz kann auch durch Umkristallisation aus geeigneten, gegebenenfalls mit Wasser verdünnten organischen Lösungsmitteln, wie Holzgeist, Alkohol oder dgl. gereinigt werden. Colorless resin can be produced from it by distillation, which is best done by means of Water vapor and is filled in a vacuum. The resin can also be obtained by recrystallization from suitable organic solvents, optionally diluted with water, such as wood spirit, Alcohol or the like. Be cleaned. PATENT-ANSPRUCH 'Verfahren zur Herstellung von Harz aus harzreichem Holz, dadurch gekennzeichnet, dass das Holz unter Druck mit so starker Alkalilösung gekocht wird, dass es von der Lauge vollständig gelöst wired und das Harz in harzsaures Alkali überfulut wird. PATENT CLAIM 'Process for the production of resin from resin-rich wood, characterized in that the wood is boiled under pressure with such a strong alkali solution that it is completely dissolved by the lye and the resin is flooded with resin-acid alkali.
