Thermodynamic and acoustic properties of binary mixtures of ethers. V. Diisopropyl ether or oxolane with 2- or 3-chloroanilines at 303.15, 313.15 and 323.15 K

摘要

Densities ρ and speeds of sound u, of binary mixtures formed by 2-chloroaniline or 3-chloroaniline with diisopropyl ether or oxolane have been measured over the entire range of composition at a temperature of (303.15, 313.15 and 323.15 K) and atmospheric pressure. The ρ and u values were used to calculate isentropic compressibilities κ_S, Rao's molar sound functions R, intermolecular free lengths L_f, specific acoustic impedances Z, excess molar volumes VmE, excess isentropic compressibilities κSE, excess intermolecular free lengths LfE and excess specific acoustic impedances Z~E. The results have been used to investigate molecular interactions and structural effects in these mixtures. The speed of sound in present mixtures has been estimated using several empirical and theoretical models to determine their relative predicting ability in terms of pure component properties.
