Densities, speeds of sound, refractive indices, excess and partial molar properties of polyethylene glycol 200 + methyl acrylate or ethyl acrylate or n-butyl acrylate binary mixtures at temperatures from 293.15 to 318.15 K

摘要: Abstract The densities, ρ, speeds of sound, u and refractive indices, nD binary mixtures polyethylene glycol 200 with methyl acrylate, ethyl n-butyl including those pure liquids, over the entire composition range were measured at temperatures (293.15, 298.15, 303.15, 308.15, 313.15 318.15) K atmospheric pressure. Using experimental data, excess molar volume, VmE, isentropic compressibility, Ks, mE, speed uE, deviations in index, ΔϕnD, refraction, ΔRM have been calculated. partial volumes compressibilities, compressibilities whole range, infinite dilution also properties correlated by Redlich–Kister polynomial equation. variations these parameters temperature are discussed terms intermolecular interactions mixtures. Moreover, values ultrasonic for calculated using scaled particle theory results compared experimentally values.
