DENSITIES, SPEEDS OF SOUND, AND ISENTROPIC COMPRESSIBILITIES OF BINARY AND TERNARY MIXTURES CONTAINING CH3(CH2)(3)OH, CH3(CH2)(4)CH3, AND CH3(CH2)(3)NH2 AT A TEMPERATURE OF 298.15 K

Densities rho and speeds of sound u have been measured for {x(1)CH(3)( CH2)(3)OH + x(2)CH(3)(CH2)(4)CH3 + (1 - x(1) - x(2))CH3(CH2)(3)NH2}, a nd the corresponding mixtures {xCH(3)(CH2)(3)OH + (1 - x)CH3(CH2)(4)CH 3}, {xCH(3)(CH2)(3)OH + (1 - x)CH3(CH2)(3)NH2}, and {xCH(3)(CH2)(4)CH3 + (1 - x)CH3(CH2)(3)NH2}, at T = 298.15 K. Using these results, the i sentropic compressibilities kappa(s), the excess isentropic compressib ilities kappa(s)(E), and the speed of sound deviations Delta u, have b een calculated for both the binary mixtures and the ternary system. Ex cess isentropic compressibilities and the speed of sound deviations ha ve 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.
