Mutual diffusion coefficients of binary liquid mixtures of diethyl oxalate with ethanol and butan-1-ol at 293.15, 303.15, and 313.15 K

The mutual diffusion coefficients of binary liquid mixtures of diethyl oxalate with ethanol and butan-1-ol in the complete mole fraction range were measured by the Taylor dispersion method. Experimental results at 293.15, 303.15, and 813.15 K are reported. The data are fitted by polynomial equations with an average absolute deviation of 1%. These experimental data are also satisfactorily correlated by a recently developed local composition UNIDIF model.
