Abstract

Binding constants for the inclusion of sodium alkane-1-sulfonates (C5-C10, C12) by four modified β- cyclodextrins (2,6-O-dimethyl-β-cyclodextrin, 2,3,6-O-trimethyl-β-cyclodextrin, hydroxypropyl-β-cyclodextrin and maltosyl-β-cyclodextrin ) were determined conductimetrically at 25°C. Binding increased with increasing length of the alkyl chain. Generally, the substituted β- cyclodextrins were no more effective as encapsulating agents than ordinary β- cyclodextrin with the persubstituted 2,3,6-O-trimethyl-β-cyclodextrin being the weakest.
