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.
