This work reports the experimental density data for the binary mixtures of n-heptane or methylcyclohexane + di-isopropyl ether, measured over the full composition range between 0.1 and 140 MPa, and for temperatures from 298.15 to 393.15 K, by means of a vibrating tube densitometer calibrated with an uncertainty of 0.0007 g·cm^–3. Then, the experimental density data were fitted using a Tait-like equation to derive mixing thermodynamic coefficients, including the isobaric expansivity and isothermal compressibility. Finally, the excess volumes of the abovementioned binary mixtures were calculated, and their nonideal behavior was investigated.

二元混合物（二异丙醚+正庚烷或甲基环己烷）的高压体积性质

这项工作报告了通过振动管在0.1至140 MPa的整个组成范围内测量的正庚烷或甲基环己烷+二异丙醚的二元混合物的实验密度数据，以及在298.15至393.15 K的温度下的实验密度数据。校准的密度计，不确定度为0.0007 g·cm ^–3。然后，使用Tait式方程拟合实验密度数据，以得出混合热力学系数，包括等压膨胀率和等温压缩率。最后，计算了上述二元混合物的过量体积，并研究了它们的非理想行为。
