Kinetic regularities of cyclodextrins moleculas associates formation in
water solutions
Abstract
The surface properties of water solutions of P-cyclodextrin (p-CD) and
its oxyalkylated derivatives on division boundary with air are studied. It is
shown in the first time that the CDs under investigation are weak surfactants,
and the surface tension isotherms of their water solutions are non monotonous,
it is connect to CDs molecules association. The associates formation is proved
by Langmuir method, photon-correlation spectroscopy and computer molecular
modeling. It is established that at keeping the CDs "olding" take
place, in result which the CDs surface properties and comlexation ability are
changed.
