Selective extraction of polyhydroxy compounds using hydrophobic ionic

These hydrophobic ionic liquids showed strong selective extraction ability when fractionating mixtures composed of sugar alcohols and their dehydrated derivatives (1:1, w / w). The results showed that the purities of isosorbide and isomannide separated were more than 99.60 wt% and 99.99 wt% respectively.

Self-healing polymeric ionic liquid hydrogels with high

Abstract The poor mechanical properties of self-healing hydrogels limited their applications in the fields of biomedicine and industry. Here, a series of self-healing polymeric ionic liquid (PIL) hydrogels with high mechanical strength and electrical conductivity were prepared through hydrophobic association. Hydrophilic monomer vinyl These DL-menthol/carboxylic acid hydrophobic deep eutectic solvents are radically different in composition to the ammonium salt-based deep eutectic solvents from Kroon and co-workers (van Osch et al. 2015) and from typical choline chloride-based deep eutectic solvents (Abbott et al. 2003).They also do not build on traditional ionic liquid Hydrophobic Deep Eutectic Solvents SpringerLink

Ionic liquids and deep eutectics as a transformative platform

It has been demonstrated that in the synthesis of metal nanoparticles (NPs) from hydrophobic metal organic precursors, the size of the apolar domains in ionic liquids directly influences the resulting metal particle size. 66,67 Again, MD simulations provided structural support for this idea, as depicted in Fig. 5. 68Novel ionic liquid (IL) electrolytes based on the asymmetric (fluoromethylsulfonyl)(trifluoromethylsulfonyl)imide (FTFSI)− anion, combined with the N-trimethyl-N-butyl-ammonium (N1114)+ and N,N-diethyl-N-methyl-N(2-methoxyethyl)-ammonium (N122(2O1))+ cations, were successfully synthesized and investigated in Applied Sciences Free Full-Text Synthesis, Physical MDPI

Immobilization of carbonic anhydrase in a hydrophobic poly(ionic liquid

Poly(ionic liquid)s are interesting materials for CO 2 separation due to their affinity towards CO 2. Carbonic anhydrase, as an enzyme that catalyzes the hydration reaction of CO 2, represents tremendous opportunities for enhanced CO 2 capture in aqueous solutions. Yet, when used as a free enzyme solubilized in the liquid medium, it Poly(ionic liquid)s (PILs), also called polymerized ionic liquids, refer to a subclass of polyelectrolytes that feature an ionic liquid (IL) species in each monomer repeating unit, connected through a polymeric backbone to form a macromolecular architecture.

Frontiers Use of Ionic Liquids in Protein and DNA

Hydrophobic ionic liquids are easier to separate from aqueous mixture than hydrophilic one because of their water-immiscible nature. Membrane separation is a well-known, cost-effective, and Ionic liquid-modified silica, which consists of bulky organic cations that are combined with inorganic or organic anions, has recently been developed as a new sorbent material.

Hydrophobic ionic liquids for quantitative bacterial cell lysis

DNA is one of the most frequently analyzed molecules in the life sciences. In this article we describe a simple and fast protocol for quantitative DNA isolation from bacteria based on hydrophobic ionic liquid supported cell lysis at elevated temperatures (120–150 °C) for subsequent PCR-based analysis. From a set of five hydrophobic ionic Solvent extraction of metal cations from aqueous medium, uses hydrophobic ionic liquids as medium, however the hydrophobic ionic liquids are limited. The hydrophobicity in ILs is obtained using anion like hexafluorophosphate (PF 6 −) which eventually hydrolyses in acidic aqueous phase, and this acts as a disadvantage [7], [9].Dual functional behaviour of dicationic ionic liquid as
