Empirical modeling study demonstrates enhanced prediction of molecular diffusivities in diverse liquid solutions, indicating improved structural modeling for mass transfer processes.

Key Points

To establish more accurate predictive correlations for calculating molecular diffusivities of solutes at infinite dilution across diverse liquid environments.
Formulated mathematical correlation models targeting solute diffusion in normal paraffin solutions, aqueous solutions, and polar and non-polar liquid systems.
Integrated key molecular parameters for both solute and solvent, specifically molar volume, parachor, and radius of gyration.
Produced generalized correlation equations tailored to solute-solvent pairs across normal paraffin, aqueous, and general polar/non-polar systems.
Demonstrated significant improvements in prediction accuracy over previous diffusivity estimation methods.
