Study of the Influence of Alkyl Chain Cation-Solvent Interactions on Water Structure in 1,3-Butanediol-Water Mixture by Apparent Molar Volume Data

摘要

The densities of 1,3-butanediol-water mixtures and some tetraalkylammonium iodide salt solutions in these solvent mixtures at different concentrations (0.02 M-0.14 M) have been determined at 298.15 K using magnetic float densitometer technique. Then apparent molar volumes ΦVof the electrolytes in above solvent mixtures were calculated. The apparent molar volumes of transfer ?ΦV° (tr) were also calculated and the ion-ion / ion- solvent interactions are then discussed on the basis of changes in the Masson's slope and apparent molar volumes of transfer data.
