Es hat sich nun gezeigt, dass man diesen Verseifungs- und Reinigungsprozess auf das wirksamste beschleunigen und vervollkommnen kann, wenn man ihn in einer gegebenenfalls hei/- barcn Pumpe ausführt, welche gleichzeitig das verseifte Produkt in den Destillierapparat bringt und andererseits das zu verseifende Material und die Lauge ansaugt.Die Pumpekann an t n Rtifikator auch in der Weise angeschlossen werden, dass sie aus der Rektifikationsblase dauer@@ Reaktionsgemisch absangt und es dem Apparat wieder zuführt, wobei durch die innige Mischung EMI1.1 **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. It has now been shown that this saponification and purification process can be accelerated and perfected most effectively if it is carried out in a possibly hot pump, which at the same time brings the saponified product into the still and, on the other hand, the material to be saponified and The pump can also be connected to the tn Rtifier in such a way that it can be removed from the rectification The reaction mixture sinks and feeds it back to the apparatus, with the intimate mixture EMI1.1 ** WARNING ** End of CLMS field may overlap beginning of DESC **.
