Abstract

Die Anmeldung bezieht sich auf ein Verfahren zur Messung einer sich bei einer diskontinuierlichen Phasentrennung ausbildenden Trennschicht. Diskontinuierliche Phasentrennungen kommen normalerweise im Batch- oder bei Semibatchverfahren vor, während des Ablaufs einer Flüssig-Flüssig-Extraktion oder während des Ablaufs organischer Synthesen mindestens zweier nicht mischbarer Flüssigkeiten. Die Trennschichtausbildung wird während der diskontinuierlichen Phasentrennung über eine Sonde verfolgt, die im Bereich der sich ausbildenden Trennschicht angeordnet ist. Die Sonde liefert ein von der Dispersion und der Lage der Trennschicht abhängiges Signal.
