Abstract
En 中文
• We innovatively proposed a “hydrophobic–hydrophilic synergy” design strategy and successfully screened and synthesized a high-performance ternary DES. • VLE experiments revealed that a ternary mixture containing 40 mol % TEAC:Thy:LA (1:1:2) completely breaks the BEN–MeOH azeotrope, with the NRTL model providing the most accurate prediction of the ternary phase equilibrium. • Through multiscale simulations coupled with experimental validation, we uncovered, for the first time, a cooperative separation mechanism featuring a “hydrophobic pocket–hydrophilic shell” architecture. • The work offers a green, economical, and highly efficient potential alternative for azeotropic separation.
