High pressure liquid densities and excess volumes of the (di-isopropyl ether + 1-hexanol) system

Abstract

New experimental density data for binary mixtures of (di-isopropyl ether+1-hexanol) over the composition range are reported, between 293.15 and 393.15K, and for pressures from 0.1MPa up to 140MPa. To perform these measurements, a vibrating tube densitometer, calibrated with an uncertainty of ±0.35kg·m−3 was used. The experimental density data were fitted with a Tait-like equation. From experimental data, excess volumes have been calculated as well as the isobaric thermal expansivity and the isothermal compressibility have been derived from the Tait-like equation.
