Partial molar volumes of organic solutes in water.: V.: o-, m-, and p-toluidine at temperatures from 298 K to 573 K and pressures up to 30 MPa

Density data for dilute aqueous solutions of three isomeric aminomethylbenzenes (methylanilines, toluidines) obtained in the temperature range T = 298.15 K to T = 573.15 K and either at atmospheric pressure, or at pressures close to the saturated vapour pressure of water, and at pressure p = 30 MPa are presented along with partial molar volumes calculated from the experimental data. The data were obtained using either a high-temperature, high-pressure flow vibrating-tube densimeter for measurements at elevated pressures or a commercial vibrating-tube cell DMA 602HT for measurements at atmospheric pressure.
