gewöhnliche Lufttrocknung praktisch wasserfrei erhalten werden. Es ist brennbar und enthält etwa bloss 15% Aachenbestandteile, hauptsächlich Kalk, es kann daher mit Vorteil als Brennstoff verwertet werden. Das Produkt dürfte auch als Ausgangsmaterial zur Herstellung anderer chemischer Stoffe Verwendung finden können.
Noch vorteilhaftere Resultate werden erreicht, wenn die Fällung mittels Basen mit Lüftung der Lauge kombiniert wird, durch welche die organischen Verbindungen der Lauge eine Oxydation erleiden, die in diesem Fulle die überraschende Wirkung hat, dass die Fällung der Ligninverbindungen sehr begünstigt wird. Die Lüftung kann stattfinden, während die Lauge sauer oder alkalisch ist. Am vorteilhaftesten hat es sich erwiesen, soviel des basischen Stoffes zuzusetzen, dass die Lösung schwach alkalisch ist, während die Lüftung vorgenommen wird.
Durch die Lüftung wird die Alkalinität der Lauge vermindert und dabei werden noch etwa 40% der organischen Stoffe der Lauge in derselben Form, wie oben angegeben worden ist, ausgeschieden, so dass in dieser Weise bis zu 80% des Gesamtgehaltes der Lauge an organischen Verbindungen gewonnen werden können.
Die Oxydation verläuft leichter und vollständiger, wenn sie in Anwesenheit eines Sauerstoff- überträgers stattfindet. Als solcher Zusatz kann jeder bekannte Sauerstoflüberträger verwendet werden. Ein guter Erfolg wurde mit Mangansalzen, vorzugsweise Mangansuifat, erhalten, wenn von der letztgenannten Verbindung ein Zusatz von 5 bis 10 kg pro 100 t Lauge verwendet wurde.
Die Lüftung wird zweckmässig bei der Temperatur vorgenommen, welche die Lauge besitzt, wenn sie von den Destillationsapparaten abfliesst, d. h. bei etwa 1000 C und soll bei grossen Chargen etwa 5 bis 10 Stunden dauern, wobei die Temperatur um etwa. 20 bis 30"sinkt.
Die Erfindung kann auch zur Ausseheidung der organischen Bestandteile von Destillations- Tikkst ndeu benutzt werden, die bei der Herstellung von Alkohol aus zuckerhaltigen Laugen erhalten werden, welche durch Kochung von anderen zellutosehattigen Stossen, ata Holz, z. L. Torf, mit sauren Lösungen erzeugt worden sind.

EMI2.1
ordinary air drying can be obtained practically anhydrous. It is flammable and contains only about 15% Aachen components, mainly lime, so it can be used with advantage as fuel. The product should also be used as a starting material for the manufacture of other chemical substances.
Even more advantageous results are achieved if the precipitation by means of bases is combined with aeration of the lye, through which the organic compounds of the lye undergo oxidation, which in this abundance has the surprising effect that the precipitation of the lignin compounds is very favored. Ventilation can take place while the lye is acidic or alkaline. It has proven to be most advantageous to add enough of the basic substance that the solution is weakly alkaline while the ventilation is being carried out.
The ventilation reduces the alkalinity of the lye and about 40% of the organic substances in the lye are excreted in the same form as was stated above, so that in this way up to 80% of the total content of the lye is obtained in organic compounds can be.
The oxidation is easier and more complete if it takes place in the presence of an oxygen carrier. Any known oxygen carrier can be used as such an additive. Good success has been obtained with manganese salts, preferably manganese sulfate, when an addition of 5 to 10 kg per 100 tons of lye was used of the last-mentioned compound.
The ventilation is expediently carried out at the temperature that the liquor possesses when it flows out of the distillation apparatus, i. H. at around 1000 C and should last around 5 to 10 hours for large batches, with the temperature being around. 20 to 30 "drops.
The invention can also be used for the separation of the organic components of distillation Tikkst ndeu, which are obtained in the production of alcohol from sugary alkalis, which are obtained by cooking other cellulose-saturated pots, ata wood, e.g. L. Peat, produced with acidic solutions.
