Abstract
Cyclodextrins (CyD's) have been precipitated as inclusion complexes wi th guest hydrocarbons from an aqueous medium, in which the guest hydro carbon of interest was present in various concentrations. The solubili ty product constant of the CyD precipitate at 25 degrees C was determi ned by measuring the CyD concentration in the supernatant aqueous solu tion. Five model hydrocarbons were used as guests: hexane, cyclohexane , benzene, naphthalene, and biphenyl. The solubility products and the solubility in water of alpha-, beta-, gamma-CyD inclusion complex prec ipitates with 36 varieties of guests were calculated based on the solu bility of the guest hydrocarbon in water and the concentration of free CyD in the supernatant aqueous medium.
