Infinite-Dilution Binary Diffusion Coefficients of 2-Propanone, 2-Butanone, 2-Pentanone, and 3-Pentanone in CO2 by the Taylor Dispersion Technique from 308.15 to 328.15 K in the Pressure Range from 8 to 35 MPa

Infinite-dilution binary diffusion coefficients of 2-propanone, 2-butanone, 2-pen- tanone, and 3-pentanone in carbon dioxide were measured by the Taylor disper- sion method at temperatures from 308.15 to 328.15 K and pressures from 7.60 to 34.57 MPa. The D12 values were obtained from the response curves by the method of fitting in the time domain. The accuracy in the fitting error was examined for each measurement. The measured D12 data were found to be well correlated by the Schmidt number correlation, with AAD0=3.740 for all solutes.
