Volumetric properties of aqueous solutions of glutaric acid

Densities of aqueous solutions with molalities up to 6 mol · kg−1 were determined at 5 K temperature intervals, from T = 288.15 K to T = 333.15 K. Densities served to evaluate the apparent molar volumes, V2,ϕ(m, T), the cubic expansion coefficients, α(m, T), and the changes of isobaric heat capacities with respect to pressure, (∂CP/∂P)T,m. They were qualitatively correlated with the changes in the structure of water when glutaric acid is dissolved in it.
