ABSTRACT

The densities at T = (293.15, 298.15, 303.15, 308.15, 310.15 and 313.15) K and sound velocities at T = (298.15 and 310.15) K have been measured for pentaerythritol in pure water and in (1, 5 and 10) wt % aqueous solutions of sodium and magnesium chloride. From these data apparent molar volumes and the apparent molar isentropic compressibilities of the polyol have been determined. The limiting apparent molar quantities and corresponding transfer parameters were also obtained and discussed in terms of various solute-solvent and solute-cosolute interactions.
