- 論文の詳細を見る
The formation constants of short chain alkylammonium salt-cyclodextrin complexes in aqueous solutions were investigated by conductometry for various values of alkyl chain length and the number of alkyl groups attached to the nitrogen atom. α-Cyelodextrin (α-CD). β-CD and γ-CD form complexes with alkylammonium salts having alkyl groups longer than n-butyl, n-hexyl and n-decyl, respectively. The formation constants of n-alkylammonium salts with α-CD incrcase with the number of akyl groups attached to the nitrogen atom. The entropy change of complex formation was negative. The effect of the terminal group on the complex formation is discussed in relation to the formation constants of alkanol-CD complexes.
