“…Since we have used these methods previously and described the respective instrumentation and experimental procedures in detail, given here is only a brief overview of their principles supplemented with particularities, if any, that are specific to the present application. For a full account of our experimental techniques we refer the reader to our previous papers [6][7][8][9][10].…”

“…Activity coefficients at infinite dilution of a solute i (γ ∞ i ) can be used to quantify the volatility of the solute as well as to provide information on the intermolecular energy between solvent and solute. (10,11) Recently, activity coefficients in solutions of imidazolium-based ionic liquids and water including Henry's law coefficients have been published by Anthony et al (12) Our interest in ionic liquids is focussed on providing systematic data on activity coefficients in mixtures with organic solvents. Various ionic liquids are commercially available.…”

“…Darüber hinaus stehen die Apparaturen, die für die unterschiedlichen Verfahren benötigt werden, in der Regel nicht zur Verfügung. Aus diesem Grund soll in dieser Arbeit eine neue und einfache Variante der Rayleigh-Destillationsmethode [6,7] Dohnál und Horáková [7] konnten zeigen, dass die Genauigkeit der Messung bei der Rayleigh-Destillationsmethode von der Höhe des Verdampfungsverhältnisses m e /m 0 sowie von der Höhe des Verteilungsfaktors in unendlicher Verdünnung abhängt. Im Allgemeinen kann gesagt werden, dass mit steigendem K ∞ i immer weniger verdampft werden muss, um eine gewünschte Genauigkeit zu erreichen.…”

“…Da nur das Verhältnis der Konzentrationen einer Aromakomponente in der Flüssigkeit vor und nach der Verdampfung zur Ermittlung von K ∞ i benötigt wird, können aufgrund der Proportionalitäten sowohl eine gemessene Extinktion als auch eine ermittelte Peak-Fläche direkt in Gl. (2) eingesetzt werden [4,7].…”
