摘要

Simulations and experiments were carried out to explore the solvent extraction of ethanol from aqueous solution using a series of seven 10-carbon alcohols. It is shown that configurational-bias Monte Carlo simulations in the Gibbs ensemble coupled with the TraPPE-UA force field can be utilized for predictive screening of the different extraction abilities (in terms of capacity factor and selectivity) of these alcohols. Analysis of the simulation trajectories indicates that extraction capacity is connected to the stabilization of larger ethanollwater cluster in the organic solvent, whereas selectivity is improved when smaller ethanollwater clusters are more prevalent.
