Abstract Sound speed measurements in 42 ternary aqueous mixtures of ethanol plus 1-propanol and new measurements in the three binary mixtures, composed by the three same components, were made at T = 293.15 K and P = 0.1 MPa. Following the volumetric study recently published, a compressibility analysis is now presented in order to complement our previous work, mainly based on derived properties such as excess partial molar isentropic compressions of the three components and their limiting values. As far as we know curves for limiting excess partial molar isentropic compressions of the i component in the ternary mixture were derived for the first time. Transfer functions of these limiting values when water and alcohol molecules are transferred from the aqueous binary to the ternary mixture, are presented and interpreted in terms of hydrophobic hydration and H-bonding effect.

三元液体混合物（水 + 乙醇 + 1-丙醇）在 T = 293.15 K 和 P = 0.1 MPa 时的超声速度研究

摘要 在 T = 293.15 K 和 P = 0.1 MPa 的情况下，对 42 种乙醇加 1-丙醇的三元含水混合物进行了声速测量，并对由三种相同组分组成的三种二元混合物进行了新测量。在最近发表的体积研究之后，现在提出了压缩率分析，以补充我们以前的工作，主要基于派生的属性，例如三个组分的过量部分摩尔等熵压缩及其极限值。据我们所知，首次导出了限制三元混合物中 i 组分过量部分摩尔等熵压缩的曲线。当水和醇分子从含水二元混合物转移到三元混合物时，这些极限值的传递函数，
