   gedampft und mit. Kalk (Ca 0) oder mit Kalk und Natronlauge versetzt, wobei aber die Natronlauge infolge des Abganges der Humusstoffe in geringerer Menge erforderlich ist ; man braucht   in diesem Falle nur etwa ein Viertel bis ein Drittel der eben angegebenen Menge. 



   Will man nach dem Prinzip des   Ammoniakaodaverfahrens   die Ablauge behandeln, so werden zunächst die Humusstoffe abgeschieden und darauf wird die in der Ablauge enthaltene   Essig- und Ameisensäure   in bekannter Weise als Ammoniaksalz abdestilliert. Aus der davon befreiten Ablauge wird das Ammoniak durch   Kalkzusatz   wie üblich entfernt und darauf der Rückstand in der beschriebenen Weise bei Gegenwart von Kalk und Natronlauge trocken destilliert. Eine solche Trennung der Humusstoffe, Essig-und Ameisensäure kann auch in anderer Weise erfolgen.

1.

   Verfahren zur Gewinnung von Alkoholen, Aldehyden und Ketonen, dadurch gekennzeichnet, dass man die in den Ablaugen der   Natron- oder Sulíatzellulosefabrikation   enthaltenen   Humusstoffe, Humussäuren   und Oxysäuren entweder in isoliertem Zustande oder in Form der Ablaugen bei Gegenwart von starken Basen trocken destilliert.

   steamed and with. Lime (Ca 0) or mixed with lime and sodium hydroxide solution, but the sodium hydroxide solution is required in smaller quantities due to the loss of humus substances; in this case only about a quarter to a third of the amount just given is needed.



   If you want to treat the waste liquor according to the principle of the ammonia caustic process, the humus substances are first separated and then the acetic and formic acid contained in the waste liquor is distilled off in a known manner as ammonia salt. The ammonia is removed from the waste liquor freed from it as usual by adding lime and the residue is then distilled dry in the manner described in the presence of lime and sodium hydroxide solution. Such a separation of the humus substances, acetic and formic acid can also take place in another way.
 EMI2.1
 
1.

   Process for the production of alcohols, aldehydes and ketones, characterized in that the humus substances, humic acids and oxy acids contained in the waste liquors from sodium or sulphate cellulose production are distilled dry either in an isolated state or in the form of the waste liquors in the presence of strong bases.

The method according to claim 1, characterized in that the suitably concentrated alkali is spread dry and distilled in thin layers, the alcohols, aldehydes and ketones formed distilling together with the water vapors developing in the process.
