Density data for dilute aqueous solutions of aniline (aminobenzene) in the range T = 298.15 K to T = 573.15 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, together 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.
