Zihao Su et al.

Summary: In this study, deep eutectic solvents (DESs) were used to treat azeotropic systems in acetonitrile wastewater. The performance of DESs in liquid-liquid equilibrium conditions was investigated through experiments and molecular dynamics simulations, confirming the feasibility of separating azeotropic mixtures using DESs and exploring the underlying mechanisms. The results showed that hydrophobic DESs had a good extraction effect on acetonitrile, with electrostatic force playing a leading role.

Yinggui Xu et al.

Summary: Two novel processes combining liquid-liquid extraction with extractive distillation or azeotropic distillation are proposed to reduce energy consumption and improve the efficiency of IBE purification. The results show that the thermal integrated process of liquid-liquid extraction combined with extractive distillation is the best design, with significantly reduced energy consumption.

Design and optimization for the separation of tetrahydrofuran/isopropanol/water using heat pump assisted heat-integrated extractive distillation

Yinggui Xu et al.

Summary: This study focuses on the separation of a ternary mixture using extractive distillation, with dimethyl sulfoxide as the optimal solvent. By introducing vapor recompressed heat pump technology and heat integration, significant energy savings were achieved. Direct extractive distillation was found to be better than indirect extractive distillation, with double-heat pump assisted direct extractive distillation showing the best performance in energy conservation and cost reduction.

Separation of Benzene-Cyclohexane Azeotropes Via Extractive Distillation Using Deep Eutectic Solvents as Entrainers

Fang Bai et al.

Summary: This study utilized deep eutectic solvents (DES) for the separation of benzene and cyclohexane azeotrope, successfully breaking the azeotrope with a relative volatility up to 4.763. The NRTL modeling approach was found to fit the experimental data well, and the mechanism from FT-IR suggested hydrogen bonding and pi-pi bond interactions as the key factors for breaking the azeotrope.

Chen Fan et al.

Summary: This study investigated the relationship between viscosity and non-covalent interactions in NADES, revealing that the number and lifetime of hydrogen bonds, as well as non-bonded interactions energy, influence the viscosity. Additionally, the relatively high viscosity was mainly driven by the enhancement of van der Waals force.
