Die Zerlegung eines Gemisches von Roh‐Thevetin in die Komponenten Cerberosid und Thevetin A mit Hilfe einer neuen Apparatur zur vielstufigen Verteilung zwischen zwei flüssigen Phasen

Using a multistage extraction apparatus of a new type, crude Thevetin was separated into the two components Cerberoside (Thevetin B) and Thevetin A. The solvent consumption was low and there was no disturbing emulgation of the phases in each other. The separation efficiency corresponds with the approximate calculations based on distribution coefficients and ratio of flow rates.
