Developing absorbents with both high absorption capacity of H 2 S and large selectivity of H 2 S/CO 2 is very important for natural gas sweetening process. To this end, a class of novel hydrophobic protic ionic liquids (ILs) containing free tertiary amine group as functional site for the absorption of H 2 S were designed in this work. They were facilely synthesized through a simple Temperature- and pH-triggered reversible transfer of doubly responsive hairy particles between water and a hydrophobic ionic liquid. Jonathan M.

Mutual Solubility of Hydrophobic Ionic Liquids and Water

Liquid–liquid two-phase systems formed by a hydrophobic ionic liquid and water find several useful ways of application in analytical chemistry. One of the most important properties of such two-phase systems is the mutual solubility of the IL and water. Recent advancements on

A liquid/liquid interfacial reaction system was designed to fabricate α‐Fe 2 O 3 cubes. The reaction system uses a hydrophobic ionic liquid containing iron ions ([(C 8 H 17) 2 (CH 3) 2 N]FeCl 4) for manufacturing α‐Fe 2 O 3 cubes by a novel and environmentally friendly hydrothermal method under low‐temperature conditions (140 C). The iron‐containing ionic liquid is hydrophobic and

In this study, a modified silica gel surface with a hydrophobic ionic liquid (SG-1,10-PhenanNTf2) was used as an adsorbent for a selective extraction of coumarin prior to its determination by use of high performance liquid chromatography. Results demonstrated that SG-1,10-PhenanNTf2 phase had a good adsorption capacity up to 85.29 mg?g?1, high selectivity, good site accessibility and fast

Ionic Liquids: Synthesis and Applications in Catalysis

Ionic liquids have emerged as an environmentally friendly alternative to the volatile organic solvents. Being designer solvents, they can be modulated to suit the reaction conditions, therefore earning the name "task specific ionic liquids." Though primarily used as solvents, they are now finding applications in various fields like catalysis, electrochemistry, spectroscopy, and material

This article describes the effect on the efficiency of a fully aqueous dye-sensitized solar cell (DSSC) after the anchoring of the hydrophobic and halogen-free ionic liquid (IL) trioctylmethyl ammonium dodecanedioate (DTMA) on its titanium oxide (TiO2) photo-anode surface.

Pure ionic liquids ([BMIM]: 1-butyl-3-methylimidazolium, X: Cl and I) and their aqueous solutions were loaded on top of non-polar solvent CCl 4, and the infrared spectra of CCl 4 phase were taken as a function of time for in-situ probing of the transfer of the ionic liquid and water molecules. We observed clear vibrational bands of methyl and methylene groups of the cations similar to that of

ABSTRACT. In this study, a modified silica gel surface with a hydrophobic ionic liquid (SG-1,10-PhenanNTf 2) was used as an adsorbent for a selective extraction of coumarin prior to its determination by use of high performance liquid chromatography.Results demonstrated that SG-1,10-PhenanNTf 2 phase had a good adsorption capacity up to 85.29 mg∙g −1, high selectivity, good site

Surfactant molecules have a hydrophilic (attracted to water) and hydrophobic (repels water) tails. In cleaning products, this means the hydrophobic tail holds the dirt and oil from reentering the cleaned surface while the hydrophilic tail helps in disinfecting the surface. This is why many cleaners have nonionic surfactants.

Hydrophobic ionic liquids (IL) have the potential to simplify certain separations by serving as both an extraction solvent and an electrolyte for subsequent electrochemical reductions. While IL-based solvents are known to be efficient media for metal ion extraction, separations employing these solvents are frequently complicated by the loss of

The solubility of a substance in a liquid is determined by intermolecular interactions, which also determine whether two liquids are miscible. Solutes can be classified as hydrophilic (water loving) or hydrophobic (water fearing). Vitamins with hydrophilic structures are water soluble, whereas those with hydrophobic structures are fat soluble.

Dec 10, 2019Obesity is considered a strong factor in many chronic diseases, including heart disease, diabetes, and cancer. Along with genetics, consumption of excessive fat and cholesterol-rich food are the primary causes of obesity. We have developed an ionic liquid that interacts with fat to form micrometer-sized particles. The ionic liquid prevents the fat from penetrating through the intestinal membrane.

Affinity of estrone on imidazolium-based hydrophobic ionic liquids was computed at the B3LYP/6-31G(d) level. Columbian interactions and other closed-shell interactions, in general, were observed to be pivotal to the binding of the EDC species on visualizing the optimized structures as well as probing the proximity of electronegative and electropositive groups between estrone and ionic liquids.
