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-pentanone, and 3-pentanone in carbon dioxide were measured by the Taylor dispersion method at temperatures from 308.15 to 328.15 K and pressures from 7.60 to 34.57 MPa. The D-12 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 D-12 data were found to be well correlated by the Schmidt number correlation, with AAD% = 3.74% for all solutes.
