Abstract
This work reports new experimental density data for binary mixtures of 2-butanol+di-isopropyl ether over the composition range, between 293.15 and 393.28K, and for 23 pressures from 0.1MPa up to 140MPa. A vibrating tube densitometer, calibrated with an uncertainty of ±0.7kg·m−3 was used to perform these measurements. The experimental density data were fitted with a Tait-like equation with low standard deviations. Excess volumes have been calculated from the experimental data. In addition, the isobaric thermal expansivity and the isothermal compressibility have been derived from the Tait-like equation.
