Partial molar volumes of organic solutes in water. II. Dihydroxybenzenes at temperatures T = (298 to 473) K and pressures up to 30 MPa
Density data for dilute aqueous solutions of three dihydroxybenzenes in the temperature range (298.15 to 473.15)K and at either atmospheric pressure, or at pressures close to the saturated vapour pressure of water, and at elevated pressures up to p = 30 MPa are presented along with partial molar volumes calculated from the experimental data. The data were obtained using both a high-temperature high-pressure flow vibrating-tube densimeter, and a commercial vibrating-tube cell DMA 602HT.
