Excess molar volumes, viscosity deviations, excess isentropic compressibilities and deviations in relative permittivities of (alkyl acetates (methyl, ethyl, butyl and isoamyl) + n-hexane, + benzene, + toluene, + (o-, m-, p-) xylenes, + (chloro-, bromo-, n

The experimental densities (ρ), dynamic viscosities (η), speeds of sound (υ) and relative permittivities (εr) of thirty six binary mixtures of esters (methyl acetate, ethyl acetate, butyl acetate and 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 and temperatures (298.15 to 313.15 K). The excess molar volumes, VmE, excess isentropic compressibilities, κsE, deviations in relative permittivities, δεr have been calculated and fitted to Redlisch-Kister type equation. The dynamic and kinematic viscosities have been correlated through Grunberg-Nissan and MacAllister equations. The qualitative analysis of various functions revealed that i.) esters lose their dipolar association in presence of inert and unlike n-hexane, ii.) specific but weaker n…π type interactions predominate in binary mixtures of esters + aromatic organic solvents and iii.) weak electron donor-acceptor complexes predominate in the mixtures of esters with halogenated and nitrated benzene.
