INCLUSION COMPLEXATION OF VOLATILE CHLORINATED HYDROCARBONS IN AQUEOUS-SOLUTIONS OF BRANCHED CYCLODEXTRINS

The inclusion complexation of five volatile chlorinated hydrocarbons, i.e., chloroform, carbon tetrachloride, trichloroethylene, tetrachloro ethylene, and monochlorobenzene, with branched cyclodextrins (CDs) suc h as monoglucosyl-alpha-CD and monomaltosyl-beta-CD in aqueous solutio ns was examined. Their inclusion complexes were found to be very water soluble and the solubilities of the chlorinated hydrocarbons in aqueo us solutions increased almost linearly or gradually with increasing co ncentration of the branched CDs. The amounts of the chlorinated hydroc arbons included in the branched CDs were well related to their molecul ar size and shape. In addition, the viability of application to pollut ion prevention is discussed.
