Infinite dilution binary diffusion coefficients of C-5-monoalcohols in water were measured by the Taylor dispersion method at 273.2 K to 353.2 K and 0.1 MPa. At each temperature it was found that the D-12 values for the isomers increase with the boiling point of the pure alcohols. The D-12 values were correlated with temperature, water viscosity, and solute boiling point. The accuracy in the correlation was superior to the various correlations reported in the literature.
