Properties of methanol and acetone in dilute aqueous solutions

Abstract

The apparent molar volume Φ_v of methanol and acetone in dilute aqueous solutions was determined from density measurement at 293 K. The limiting apparent molar volumes at infinite dilution of these organic liquids were calculated by Masson's equation. The variation of Φ_v with concentration was also discussed in terms of liquid structure. Viscosity coefficient A and B for both liquids were determined by Jone–Dole equation. This liquid exhibits strong solute–solvent interactions. Grunberg–Nissan constant d ₁₂ was also calculated from the viscosity data, which indicates the formation of associating clusters in the solution. A new modified Jone–Dole equation was also applied with the experimental results, which was applied for both liquids as solute in dilute aqueous solutions.
