Abstract
New experimental density data are reported for binary mixtures of 2-propanol + di-isopropyl ether over the composition range (6 compositions; 0.15 â¤Â 2-propanol mole fraction xâ¯â¤â¯0.85), between 293.15 and 393.28â¯K, and for 23 pressures from 0.1â¯MPa up to 140â¯MPa. Measurements were performed by means of an Anton Paar vibrating tube densitometer, calibrated with an uncertainty of 7â¯Ãâ¯10â4â¯gâ¯cmâ3. A Tait like equation was used to fit the experimental density data, with low standard deviations. Excess volumes have been calculated from the experimental data and fitted by the Redlich-Kister equation. Moreover, the isothermal compressibility and the isobaric thermal expansivity have been derived from the Tait-like equation.
