Modeling Infinite Dilution and Fickian Diffusion Coefficients of Carbon Dioxide in Water
We propose a new model for calculating infinite dilution diffusion coefficients for carbon dioxide and water mixtures. The model takes into account temperature dependence of the dipole moment of water and polarizability of CO2, and fits experimental CO2AH2O data at low and high pressures with an accuracy of 4.9%. Remarkably, the proposed model also accurately predicts infinite dilution diffusio...
متن کاملMeasurements of Binary Diffusion Coefficients for Ferrocenes in Supercritical Carbon Dioxide
The binary diffusion coefficients of ferrocene and 1,1’-dimethylferrocene at infinite dilution in supercritical carbon dioxide, D12, were measured by the chromatographic impulse response (CIR) method at temperatures from 308.2 to 323.2 K and pressures from 9 to 40 MPa. The D12 data for ferrocene were also measured by the Taylor dispersion method. The diffusion data of ferrocene measured by the ...
متن کاملDevelopment of a high-pressure set-up for measurements of binary diffusion coefficients in supercritical carbon dioxide.
We present the development of a high-pressure apparatus for measurements of diffusion coefficients in supercritical fluids. The Taylor dispersion method has been adapted to conduct experiments at the pressures up to 25.0 MPa. In order to test the developed set-up, binary diffusion coefficients D at infinite dilution in supercritical carbon dioxide have been measured for a reference system, benz...
متن کاملMeasurements of activity coefficients at infinite dilution of organic solutes and water on polar imidazolium-based ionic liquids
The activity coefficients at infinite dilution, c13, of 55 organic solutes and water in three ionic liquids with the common cation 1-butyl-3-methylimidazolium and the polar anions Cl , [CH3SO3] and [(CH3)2PO4] , were determined by (gas + liquid) chromatography at four temperatures in the range (358.15 to 388.15) K for alcohols and water, and T = (398.15 to 428.15) K for the other organic solute...
