Thermodynamic Evaluation of Micellization of an Azepanium Ionic Liquid-Based Surfactant in Water and Organic Solvent-Water Media.
A novel azepanium ionic liquid-based surfactant, 1-(2-hexadecyloxy-2-oxoethyl)-1-methylazepanium bromide (Azp-ILBS; C25H50NO2Br), was successfully obtained and structurally characterized using 1H, 13C NMR, FT-IR, HRMS, and CHNS elemental analysis. The critical micelle concentration (cmc) was evaluated via electrical co...

Preparation of N-methylimidazolium-based strongly basic macroporous resins and their adsorption performance towards aromatic acids
Herein, N-methylimidazolium-based strongly basic macroporous resins were synthesized according to bimolecular nucleophilic substitution (SN2), and they were applied to adsorb aromatic acids of different molecular weights in aqueous and isopropanol. Using chloromethylated polystyrene (PS) as the matrix and N-methylimida...

Impact of Organic Solvents, Surfactants, and Nonfunctionalized PEGs on PEGylation Reaction Yield
The optimization of PEGylation reaction yield is critical for the efficient production of therapeutic bioconjugates. This study systematically investigates the influence of three distinct classes of additives -organic cosolvents, nonreactive poly(ethylene glycols) (PEGs) of varying molecular weights, and surfactants- o...

Synergistic Effect of Brønsted and Lewis Acids in Aromatic Alkylation Catalyzed by Chloroaluminate Ionic Liquids
Chloroaluminate Ionic Liquids (CILs) are highly effective catalysts for the alkylation of aromatics with long-chain olefins, yet the individual and synergistic effects of Brønsted and Lewis acid species remain contentious. Herein, 1-methylnaphthalene and 1-decene are used as model compounds to elucidate the synergi...

ONIOM Quantum Chemical Examination of 1,3-Butadiene Polymerization Catalyzed by the Methylaluminoxane-Modified Neodymium Ziegler–Natta System
Quantum chemical modeling of the formation of active sites in 1,3-butadiene polymerization in the presence of neodymium Ziegler–Natta catalysts at the ONIOM (PBE0/def2–TZVP//GFN1-xTB) level was performed. The influence of chloride ion content and methylaluminoxane (MAO) used as a modifier on catalyst activity was studi...

Study of the interaction of a poloxamer with short and long alkyl chain imidazolium ionic liquids.
The ethylene oxide (EO)/propylene oxide (PO) triblock copolymers (EO)m-(PO)n-(EO)m, also known as poloxamers, self-assemble in aqueous solution due to the differences in hydrophobicity between EO and PO. Both the overall length of the blocks and their relative lengths in the copolymer impact self-assembly. Even though...
