Abstract

Binary diffusion coefficients D-12 of benzene at infinite dilution incarbon dioxide were measured at 313.2 K in the pressure range from 8.5 to 30 MPa by the Taylor dispersion method. At 313.2 K, the measured values in this study were slightly higher than those of Swaid and Schneider, 1979, and lower than those of Sassiat et al., 1987. It was found that the D-12 values measured with the coiled diffusion column installed vertically were lower than those when it was installed horizontally. The correlation of D-12 with solvent viscosity was effective for the D-12 of benzene, both in dense CO2 and in the liquid solvents: hexane, cyclohexane and dodecane. In addition, the measured D-12 decreasedsmoothly with increasing pressure, and there was no evidence of the anomalous decrease in D-12 at 313.2 K in the pressure range from 8.5 to30 MPa.
