Study of density of binary mixture of containing butyl acetate and benzaldehyde

acetate, benzaldehyde, aniline were measured at 293.15 to 323.15K and whole mol fraction range. Excess molar volumes (V Em ), viscosity deviations, partial molar volumes at infinite dilution (V 0m,i), thermal expansion coefficients (α) excess thermal expansion coefficients (E) and change of molar Enthalpy with pressure atconstant temperature and molar fraction T x E ( Hm / P ) , have been calculated. Excess molarvolume and viscosity deviation were fitted by Redlich - Kister equation. All mixtures show negative values of excess molar volume and viscosity deviation; Excess molar volume decrease with increase temperatures. Also the values of V E and Δη were explainted by type and nature of interactions of in solution
