    Description / Table of Contents: The time-dependence of the permeation of methanol vapour through tenside-alginate foam lamels was determined by measuring the permeation, diffusion and solubility coefficients. Steady-state transport was found to occur only within narrow time limits. The agreement of calculated and experimental relationships between the coefficients suggest solution diffusion as proposed by BARRER. The transport mechanism can be explained by the place exchange theory and by the cluster theory according to LUCK.
    Notes: Für Tensid/Alginat-Schaumlamellen wurde der Durchtritt von Methanoldampf an Hand der Permeations-, Diffusions-und Löslichkeitskoeffizienten in Abhängigkeit von der Zeit ermittelt. Stationäre Transportzustände existieren nur in engen Zeitintervallen. Aus der Übereinstimmung zwischen den berechneten und experimentell ermittelten Koeffizienten-Beziehungen wird auf eine Lösungsdiffusion nach BARRER geschlossen. Der Transportmechanismus kann auf der Grundlage der Platzwechseltheorie sowie der Cluster-Theorie nach LUCK gedeutet wurden.
