this paper focuses on the effects of the addition of an ionic liquid, 1-allyl-3-butylimidazilium bis(trifluoromethane sulfonyl)imide ([abim]tfsi), which has a high affinity for benzene, into the poly(vinyl chloride) (pvc) membrane on the pervaporation characteristics of the removal of benzene from aqueous solutions of dilute benzene. when aqueous solutions of 100～500 ppm benzene were permeated ...

a simple and rapid microextraction procedure based on the application of magnetic nanoparticles and hydrophobic 1-hexylpyridinium hexafluorophosphate [hpy][pf6] ionic liquid (il) was applied to trace determination of gatifloxacin. a mixture of [hpy][pf6] and magnetic nanoparticles was injected into the sample solution containing the analyse of interest and a cloudy solution was formed. after ce...

in this work, benzyl alcohol was obtained in 96% excellent yield by hydrolysis of benzyl chloride catalyzedby the recyclable temperature-dependant phase-separation system that comprised the ionic liquid peg1000-dail[bf4], toluene and ferric sulfate under homogeneous catalysis in aqueous media. this novel methodnot only enhanced the yield, but also made the operating units easy workup. the catal...

we used an effective electrochemical sensor for the determination of imipramine at ph 7.2 using a carbon nanocomposite electrode. the electrode has been designed by incorporation of montmorillonite nanoclay into the carbon ionic liquid electrode. the high sensitivity of 1.714 μa (μm)-1, two linear calibration ranges of 0.1–2 μm and 2-40 μm, and detection limit of 19 nm were achieved. the relati...

The synthesis of recyclable ionic liquid-supported imidazolidinone catalyst I and its application in 1,3-dipolar cycloaddition of nitrone with α,β-unsaturated aldehyde with high performance were described. Most importantly, the catalyst I can be recovered and recycled for up to five runs without observing significant decrease in catalytic activity.

A simple Pd/SiO2 catalyst which was modified with the ionic liquid [BMPL][DCA] gave an excellent yield of 88% towards cis-2-hexene in the stereoselective hydrogenation of 2-hexyne. The catalyst outperforms, even at full conversion, the commonly used lead-poisoned, toxic Lindlar catalyst and supported colloidal-based Pd as well.

Ionic liquids are organic salts that melt at low temperatures and provide a set of properties beneficial for diverse applications. These properties include good thermal stability, high ionic conductivity, low volatility and non-flammability. In this thesis protic ionic liquids have been at focus, which are of interest for use as electrolytes in next-generation proton exchange membrane fuel cell...

Efficiency of ionic liquid supported organotin reagents in halodemetalation reaction has been investigated. High radiochemical yields of astatinated and iodinated compounds have been obtained using simple work-up procedure. This methodology represents a straightforward approach for the preparation of molecular imaging and therapy agents in nuclear medicine.

membrane assisted liquid extraction(male) technologies are gaining an important role as an extraction /separation technique for actinides and are being deployed as a  promising tool for remediation of nuclear waste generated in the reprocessing plant and other radioactive wastes containing a trace level of radionuclides. the present contribution outlines the classification of membrane assisted ...

A systematic study of the kinetics supported-ionic-liquid-phase (SILP) Au catalysis (Au-IL/AC) has been established in continuous gas-phase hydrochlorination acetylene. We reveal that effect ionic liquid (IL) film on substrate diffusion can be eliminated. The reaction order catalyst indicates is confirmed to exist as a monomer IL Au-IL/AC system, which different from fast equilibrium “Au dimer ...
