Resumo: Densities of DL-alanine in aqueous ionic liquid, 1-butyl, 3-methylimidazolium tetrafluoroborate solutions were measured from 283.15 to 313.15 K. The densities measured were used to calculate apparent molar volumes (VΦ), apparent molar volume limits (VΦ0), transfer molar volume limits (ΔVΦ0) and hydration number (NH). The behavior of (ΔVΦ0) was interpreted in terms of solute-solvent interactions on the basis of the cosphere overlap model. The hydration numbers were positive and explained by dehydration and electrostriction.
