Liquid phase PVTx properties of (water + tert-butanol) binary mixtures at temperatures from 278.15 to 323.15 K and pressures from 0.1 to 100 MPa

► Coefficients of compressibility of liquid binary mixture water + tert-butanol were measured. ► Measurements were performed at pressures from 0.1 to 100 MPa and temperatures from 278.15 to 323.15 K. ► Partial molar volumes of the components and excess molar volumes of the mixture were calculated.
