Verfahren, um die in den Ablaugen der Sulfitzellulose-Fabrikation enthaltenen festen organischen Bestandteile in Wasser schwerlöslich oder unlöslich zu machen.
Die Erfindung betrifft ein Verfahren, um die in den Ablaugen der Sumtzellulose-Fabrikation enthaltenen festen organischen Bestandteile in Wasser schwer löslich oder unlöslich zu machen.
Das Verfahren besteht darin, die Ablaugen mit Säuren unter Erhitzung, gegebenenfalls auch unter Druck zu behandeln. Die Laugen, neutralisiert oder sauer, wie sie aus den Kochern kommen, werden eingedickt, z. B. bis etwa 30 B und mit Säuren unter Erhitzung behandelt. Je nach der Natur der Maure und der Temperatur'tritt schneller oder langsamer infolge geringerer Löslichkeit in Wasser ein Gelatinieren der Masse ein. Wesentlich schnelle tritt unter sonst gleichen Verhältnissen das Gelatinieren oler auch Festwerden der Masse ein, wenn die Ablauge mit einem Aldehyd versetzt und dann mit einer Säure behandelt wird. Wählt man z. B.
Formaldehyd und konzentrierte Salzsäure, so tritt beim Erhitzen fast momentan ein Erstarren der ganzen Masse
EMI1.1
Nur von Salpetersäure wird es verhältnismässig leicht angegriffen. Die Behandlung mit Säuren kann gegebenenfalls auch in geschlossenen Gefässen und unter Druck vorgenommen werden.
Auch können nach beliebigen Methoden die anorganischen Bestandteile, z. B. Kalk aus der Ab lauge vorher entfernt werden.
EMI1.2
h'tzteren Fätlen werden der Lauge oder dem Gemisch von Lange und einem Aldehyd zweck- llläLlig Faserstoffe, Zellulose und dgl. beigemischt, welche dann mit den gelatinierten HolzinkrusteneinfestesgleichmässigesGefügebilden.

Process to make the solid organic constituents contained in the waste liquors from sulphite cellulose production sparingly soluble or insoluble in water.
The invention relates to a method for making the solid organic constituents contained in the waste liquors of the total cellulose production sparingly soluble or insoluble in water.
The process consists in treating the waste liquors with acids with heating, possibly also under pressure. The lyes, neutralized or acidic, as they come from the cookers, are thickened, e.g. B. to about 30 B and treated with acids with heating. Depending on the nature of the moor and the temperature, gelatinization of the mass occurs faster or slower due to its lower solubility in water. Under otherwise identical conditions, gelatinization or solidification of the mass occurs much more quickly if the waste liquor is mixed with an aldehyde and then treated with an acid. If you choose z. B.
Formaldehyde and concentrated hydrochloric acid, the whole mass almost instantaneously solidifies when heated
EMI1.1
It is only attacked relatively easily by nitric acid. The treatment with acids can optionally also be carried out in closed vessels and under pressure.
The inorganic constituents such. B. Lime from the Ab caustic be removed beforehand.
EMI1.2
For more severe fats, fibrous materials, cellulose and the like are added to the lye or the mixture of Lange and an aldehyde, which then form a solid, uniform structure with the gelatinized wood incrustations.
EMI1.3
