Densities and viscosities of the binary mixtures of methyl 4-chlorobutyrate with benzene, toluene, o-xylene, in-xylene, and p-xylene have been measured at different temperatures (298.15, 308.15 and 318.15) K and atmospheric pressure over the whole range of compositions. The excess molar volumes were calculated from the experimental data and correlated by the Redlich-Kister polynomial equation. McAllister's three-body and four-body interaction models are also used to correlate the kinematic viscosities of these binary Mixtures.
