Abstrakt: Densities ρ and speeds of sounduhave been measured for {x1CH3(CH2)3OH +x2CH3(CH2)4CH3+ (1−x1−x2)CH3(CH2)3NH2}, and the corresponding mixtures {xCH3(CH2)3OH + (1 −x)CH3(CH2)4CH3}, {xCH3(CH2)3OH + (1−x)CH3(CH2)3NH2}, and {xCH3(CH2)4CH3+ (1−x)CH3(CH2)3NH2}, atT= 298.15 K. Using these results, the isentropic compressibilities κS, the excess isentropic compressibilities κSE, and the speed of sound deviations Δu, have been calculated for both the binary mixtures and the ternary system. Excess isentropic compressibilities and the speed of sound deviations have been fitted with the Redlich-Kister equation in the case of binary mixtures, while Cibulka's equation was used to fit the values relating to the ternary system.
