A double Savart plate birefringent interferometer was used to study the diffusional behavior of the ternary system. Acetone (1) – Benzene (2) – Methanol (3). The ternary diffusion coefficients were measured at 9 composition points covering the entire ternary diagram. The binaries forming the borders of the ternary diagram were also studied. The ternary diffusion coefficients at one composition point of the ternary system Actone (1) – Benzene (2) – Carbon tetrachloride (3) were measured and compared with previously reported data of Cullinan and Toor (18) , obtained by diaphragm cell method. Validity of the birefringent interferometric measurements when applied to the ternary liquid systems was confirmed through this comparison.
