 EMI1.1 
 



   Das weiters beschriebene Verfahren stellt eine wesentliche Verbesserung des Verfahrens gemäss Stammpatent Nr. 34873 dar, indem dasselbe gestattet, in einer einzigen Operation denselben Effekt zu erzielen, der gemäss dem Verfahren des Stammpatentes durch zwei aufeinanderfolgende Operationen erreicht wird ; in Folge dieser Ökonomie in der Erzeugung stellt das neue Verfahren einen wesentlichen weiteren technischen Fortschritt in der   Darstellung hochprozentiger   Potasche aus Schlempekohle dar. 



   Während gemäss des Stammpatentes Nr. 31873 das Einleiten der Kohlensäure in die Lauge von mindest 400 Bé dann unterbrochen wird, wenn die Konzentration der Lauge 
 EMI1.2 
 das Einleiten von Kohlensäure in eine Lauge von mindest   510   Bd so lange und zwar bei einer   zwischen 600   C und   30   C liegenden Temperatur fortgesetzt, bis die Konzentration 
 EMI1.3 
 Lauge vollständig entfallen kann. 



   Das derart in einer Operation gewonnene Kaliumkarbonat weist einen Gehalt von   91).   5 bis 99.7% K2 CO3 auf. 

**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

 EMI1.1
 



   The method described further represents a significant improvement of the method according to the parent patent no. 34873 in that it allows the same effect to be achieved in a single operation that is achieved according to the method of the parent patent by two successive operations; As a result of this economy in production, the new process represents a significant further technical advance in the production of high-percentage potash from still coal.



   While according to the parent patent No. 31873 the introduction of carbon dioxide into the lye of at least 400 Bé is interrupted when the concentration of the lye
 EMI1.2
 the introduction of carbonic acid into a lye of at least 510 Bd continued at a temperature between 600 C and 30 C until the concentration
 EMI1.3
 Lye can be completely omitted.



   The potassium carbonate obtained in this way in one operation has a content of 91). 5 to 99.7% K2 CO3.
