ABSTRACT
This work reports experimental density data for the mixtures methyl nonafluorobutyl ether (HFE-7100) + n-heptane along isotherms ranging from 298.15 to 393.15 K and at pressures from 0.1 to 80 MPa. An Anton Paar vibrating tube densimeter, calibrated with an uncertainty of +- 0.7 kg*m-3, was used to perform the measurements. The Tait-like equation was used to fit the experimental density data, with with low standard deviations. Besides, the isobaric thermal expansivity and the isothermal compressibility were derived from the Tait-like equation.
