Summary

A method of calculating aggregation numbers and radii of reversed micellar aggregates is presented and applicated on the alcohol-rich solution phaseL 2 in the model system water/decanol/sodium octanoate at 293 K. The result showing good agreement with experimental data illustrate the extension of the micellar core at different decanol contents and molar ratios water to sodium octanoate. The influence of a distribution of water between the interior of the micelle and the decanolic medium is demonstrated.

Zusammenfassung

Es wird eine Methode zur Berechnung von Aggregations zahlen und Radien invertierter mizellarer Aggregate angegeben und auf die Alkohol-reichenL 2-Lösungen im Modellsystem Wasser/Dekanol/Natrium-Oktanoat bei 293 K angewendet. Die Resultate sind in guter Übereinstimmung mit experimentellen Messungen; sie zeigen die Ausdehnung der Mizellkerne bei verschiedenen Dekanol-Konzentrationen und bei verschiedenen molaren Verhältnissen Wasser/Oktanoat. Der Einfluß der Verteilung von Wasser zwischen dem dekanolischen Medium und den Mizellen wird diskutiert.
