I. Sanemasa et al., CYCLODEXTRIN PRECIPITATES WITH NAPHTHALENE BIPHENYL MIXED GUESTS IN AQUEOUS-MEDIUM, Bulletin of the Chemical Society of Japan, 67(2), 1994, pp. 578-581
Cyclodextrins (beta- and gamma-CyDs) were precipitated in an aqueous m
edium at 25-degrees-C in the presence of a naphthalene (N)-biphenyl (B
) mixed guest. The N/B molar ratio in the precipitates was found to be
governed by S(N).K(N) (S(B).K(B))-1, where S refers to the solubility
of the guest in water and K to the 1 : 1 association constant of the
CyD-guest.
