Study of viscosity of binary mixture of containing Butyl Acetate and Benzaldehyde

density and viscosity value of binary mixtures of butyl acetate, benzaldehyde and Aniline were measured at 293.15 to 323.15K and whole mol fraction range. Excessmolar volumes (V Em ), viscosity deviations ( ), partial molar volumes at infinite dilution (V 0 m,i), thermal expansion coefficients (α) excess thermal expansioncoefficients ( E ) and change of molar Enthalpy with pressure at constant temperature and molar fractionT x E ( Hm / P ) , have been calculated. Excess molar volume and viscosity deviation were fitted by Redlich - Kister equation. All mixtures show negative values ofexcess molar volume and viscosity deviation; Excess molar volume decrease with increase temperatures. Alsothe values of V E and Δη were explainted by type andnature of interactions of in solution.
