Isothermal mass transfer was studied in a stirred cell with movable baffles using a ternary system with partially miscible solvents (water‐acetone‐glycerol). The measurements were extended from the binary solvent pair to the vicinity of the critical point. It was found that the straight line composition paths in the homogeneous regions on extensions of the equilibrium tie lines characteristic of the critical region applied over the ternary diagram. The results could not be explained even qualitatively by assuming mass transfer without driving force interactions. The principles of irreversible thermodynamics were used to explain the observations and to evaluate the appropriate mass transfer coefficients.
