摘要: Abstract The experimental densities ( ρ ), dynamic viscosities η speeds of sound υ ) and relative permittivities e r thirty six binary mixtures esters (methyl acetate, ethyl butyl acetate isoamyl acetate) + organic solvents n -hexane, benzene, toluene, o -, m p - xylenes), halogenated benzene (chloro-, bromobenzene), nitrobenzene have been measured over the complete composition range at atmospheric pressure temperatures (298.15 to 313.15 K). excess molar volumes, V E , isentropic compressibilities, κ s deviations in permittivities, δ calculated fitted Redlisch–Kister type equation. kinematic correlated through Grunberg–Nissan MacAllister equations. qualitative analysis various functions revealed that i.) lose their dipolar association presence inert unlike ii.) specific but weaker … π interactions predominate esters + aromatic iii.) weak electron donor–acceptor complexes with nitrated benzene.
