Separation of ethyl acetate and ethanol by imidazole ionic liquids based on mechanism analysis and liquid–liquid equilibrium experiment

Unveiling glutamic acid-functionalized LDHs: understanding the Cr(vi) removal mechanism from microscopic and macroscopic view points

“…9a, the resulting scatter diagram obtained among IRI and sign( λ 2 ) ρ can accurately identify the features of IRI, where the points crossing the dashed line constitute the grid points of the equivalence surface. 56 When sign( λ 2 ) ρ > 0.01 a.u., it indicates that there was a significant spatial site resistance between molecules. In the region of sign( λ 2 ) ρ = −0.02 to −0.1 a.u., a clear peak appears, indicating a clear van der Waals interaction between the HCrO 4 − molecule and the glutamic acid molecule, which corresponds to the green region between the two molecules in Fig.…”

Influence of Alkyl Chain Length of Alcohols on the Extraction Efficiency of 3-Methoxybutyl Acetate in Aqueous Solution (C5–C8 as Examples): Experimental Study, Thermodynamic Modeling, and Molecular Interaction Analysis

“…However, since water and 3-methoxybutyl acetate form an azeotropic system, traditional distillation processes cannot easily separate the azeotropic mixture, and special separation processes are therefore required. In industry, the methods commonly used for separating azeotropic mixtures are azeotropic distillation, , extractive distillation, , reactive distillation, , and liquid–liquid extraction. − Among them, liquid–liquid extraction is a simple and low-energy-consumption method that requires a simple device, making it ideal for separating and purifying various azeotropic mixtures . Therefore, liquid–liquid extraction is an effective method for separating 3-methoxybutyl acetate from its azeotropic solution.…”
