Measurements of densities, viscosities, speeds of sound and relative permittivities and excess molar volumes, excess isentropic compressibilities and deviations in relative permittivities and molar polarizations for dibutyl ether + benzene, + toluene and + p-xylene at different temperatures

摘要: Abstract The densities ρ , dynamic viscosities η speeds of sound u and relative permittivities e r for (dibutyl ether + benzene, or toluene, p -xylene) have been measured at different temperatures over the whole composition range atmospheric pressure. mixture correlated with semi empirical equations. Calculations speed based on Nomoto’s equation found to be close experimental values three mixtures two temperatures. Excess functions such as excess molar volumes V m E isentropic compressibilities κ s deviations in δe polarizations δP were calculated fitted Redlich–Kister type
