ABSTRACT

The Taylor dispersion technique was used to measure the diffusion coefficients of benzene, chlorobenzene, ethylbenzene, toluene, p-chlorotoluene, naphthalene, pyrene, and perylene at infinite dilution in mixtures of hexane + octane, hexane + decane, heptane + octane, heptane + decane, octane + decane, cyclohexane + hexane, cyclohexane + heptane, cyclohexane + octane, and cyclohexane + decane at 298.15 K. Experimental data were correlated satisfactorily by means of the Leffler-Cullinan equation using the measured values of solutes in the pure solvents and a group contribution method for estimating the viscosity of the solvent mixtures.
