The densities of aqueous solutions of D-glucose were measure at temperatures from (293.15 to 433.15) K and pressures from (0.10 to 50.00) MPa using a vibrating-tube densimeter.  Apparent molar volumes V_φ,m and partial molar volumes at infinite dilution V^∞ were calculated from the experimental results. V^∞ increases as temperature increases and varies linearly with temperature above ~300 K. In addition, V^∞ does not vary as a function of pressure up to 50.0 MPa.  Comparison of these results with previous studies indicate excellent agreement and significantly extend the experimental database for aqueous solutions of D-glucose to elevated temperatures and pressures. 

Density measurements were obtained with a commercially available Anton Paar vibrating-tube densimeter (DMA HP). A high pressure fluid manifold was constructed to deliver the fluids to the densimeter.  Densities of pure water and aqueous D-glucose solutions were experimentally measured.  The apparent molar volumes calculated from the experimentally-determined density data using the molar mass of D-glucose (180.15588 g·mol^-1).  The partial molar volume at infinite dilution was determined from the intercept of a least squares fit of the apparent molar volume (at constant pressure and temperature). 

Data include densities, apparant molar volumes and partial molar volumes for D-glucose solutions.

Uncertainty in density is ±0.0001.

Uncertainty in apparent molar volume varies as a function of concentration.  See fig. 4.

Uncertainty in parial molar volume at infinite dilution is ±1.0 cm3/mol.
