Sažetak

The active interest aroused by catalytically affected reactions
in apolar surfactant solutions requires one to look for a relation to
micelle formation and solubilization in an effort to attain a more
unified description of phenomena peculiar to apolar surfactant
systems.
Since these catalytic phenomena are usually summarized by
the notion »micellar catalysis« the present paper wants to contribute
towards a sound abstraction of this concept. This was done by
analyzing a particular catalyzed reaction (the catalyzed hydrolysis
of p-nitrophenylacetate in the presence of dodecylammoniumpropionate
in cyclohexane) in the frequently investigated apolar solutions
of cationic surfactants. A quantitative description of the
overall reaction was obtained which was found in satisfactory agreement
with experimental details. It was concluded that micellar and
multiple association patterns are reflected also in the relationships
obtained by examining catalytically influenced reactions in these
systems.
