Molar excess volumes of binary and ternary mixtures containing chloroaniline

Molar excess volumes, V E , for m-chloroaniline+benzene, +toluene, +o-xylene, +m-xylene, and +p-xylene, m-chloroaniline+benzene+toluene, and m-chloroaniline+benzene+o-xylene have been measured as a function of composition at 308.15 K. V E values for the binary mixtures are negative for all the systems over the entire range of composition and for an equimolar composition vary in the order o-xylene>toluene> m-xylene>benzene>p-xylene. On the other hand while V E values for m-chloroaniline+benzene+toluene are negative over the whole composition range, those for m-chloroaniline+benzene+o-xylene vary from positive to negative depending on the mole fraction of each of the components
