In this work we measure the density and viscosity of the ternary system benzyl alcohol (1) + benzaldehyde (2) + toluene (3) at 293.15 K and 0.1 MPa for 21 different ternary composition sets. Values of the viscosity and density of the respective binary systems, over the whole composition range at the same temperature and pressure conditions, are also presented. Experimental data of binary systems were used to determine the excess molar volumes and the viscosity deviations which were fitted by means of Redlich−Kister polynomials. The experimental data of the dynamic viscosity of the binary systems have been used to obtain the binary interaction parameters of a model recently proposed in the literature by our group. The overall mean relative standard deviation between experimental and calculated viscosities for the ternary system was 1.1%.
