Partial molal volume of DMSO and Me 2CO in the mixture of water and t-butyl alcohol (TBA) at 278.15, 288.15 and 298.15 K

Abstract

Volume measurement can be used in the evaluation of the molecular interaction in solution. The apparent molal volumes V a of DMSO and Me 2CO in the concentration range 0.2–1.4 mol per kg of solvent in mixed solvents of TBA and water were calculated from density data. The apparent molal volume of DMSO and Me 2CO at infinite dilution − V o was determined by extrapolation. The variation of − V o with the composition of binary mixed solvent was indicated in plots. The contribution of molecular interaction and structure to solution volumes was discussed.
