Abstract

Hydronated-deuterized binary mixtures of alkanes are studied by measuring the surface tension with the Wilhelmy plate method. These materials demonstrate surface freezing. Although there is interest in these technologically important substances for uses in industry, the surface freezing phenomenon has received little attention. Other studies of hydronated-hydronated alkanes have revealed a (?n / n[sub avg])^2 relation between repulsive interaction and chain mismatch. Here hydronated-deuterized mixtures are found to demonstrate the same interaction as hydronated-hydronated mixtures. Repulsive interaction is found to be proportional to (?n / n[sub avg])^2 on both the surface and in the bulk of the binary mixtures studied.
