The interaction parameters for solutions of n-butylurea in aqueous solutions of N-methylacetamide – The volumetric and compressibility studies between 288.15 K and 308.15 K
Abstract
Densities and speed of sound were measured for solutions of n-butylurea in aqueous solution of Nmethylacetamide 2, 4, 6 and 8 (mol/kg) at T = (288.15, 298.15 and 308.15) K. From these data the apparent molar volumes, Vf, the apparent molar isentropic compressions, KSf, of the solute were determined. The concentration dependencies of the calculated quantities have been used to obtain the standard partial molar parameters. The latter values were combined with the previously published volumetric and compressibility data for n-butylurea in pure water to obtain the partial molar properties of transfer from water to aqueous N-methylacetamide solutions. These parameters were used to determine the interaction parameters according to the McMillan-Mayer theory. The calculated parameters and their temperature characteristics are discussed in terms of solute–solvent, solute–solute and solute–cosolute interactions.
