This review presents the synergistic effect in the catalytic system of ionic liquids (ILs) for the synthesis of cyclic carbonate from carbon dioxide and epoxide. The emphasis of this review is on three aspects: the catalytic system of metal-based ionic liquids, the catalytic system of hydrogen bond-promoted ionic liquids and supported ionic liquids. Metal and ionic liquids show a synergistic ef...

We extend the adiabatic bond charge model, originally developed for group IV semiconductors and III-V compounds, to study phonons in more ionic IIVI compounds with a zincblende structure. Phonon spectra, density of states and specific heats are calculated for six II-VI compounds and compared with both experimental data and the results of other models. We show that the 6parameter bond charge mod...

A method to predict the ionic conductivity of LiPON solid electrolytes is presented which based on thermodynamic modelling formation oxynitride compounds in system Li 2 O–P O 5 –P 3 N .

In this paper geometry optimization of two ionic complexes such as Cr042-Gly+1, and Mo042- Gly+I have been carried out at the HF and B3LYP levels oftheory with 6-31G* basis set in the gas phase. Moreover, chemical shift andnatural bond of orbital (NBO) of these compounds have been obtainedusing NMR and NBO methods. Finally, the obtained theoretical results werecompared with each other.

In the present work, six protic ionic liquid (PIL) compounds based on p-toluene sulfonic acid [PTSA] anion along with different cations viz. tetraethylenepentammonium [TEPA], triethylammonium [TEA], pyridinium [Py], N-methylpiperidinium [Pip], 1-methylimidazolium [Im], and N-methylpyrrolidinium [Pyrr] were synthesized using standard neutralization reaction method. The structural characterizatio...

For the first time, the partition coefficients of the ionized forms of several opioids, amphetamine-like drugs, and their metabolites were determined by studying their ionic transfer process across the bare interface water/organic solvent. The ionic partition coefficients of the monocationic forms of 12 compounds--heroin, 6-monoacetylmorphine (6-MAM), morphine, acetylcodeine, codeine, dihydroco...

Palladium nanoparticles (NPs) stabilized by ImS3-14, a zwitterionic surfactant structurally related to ionic liquids, are revealed here to be good catalysts for the reduction of a large number of substituted aromatic nitro compounds. Our mass spectrometry results are consistent with the formation of amino products in a direct route, where the aromatic nitro compounds are initially reduced to ni...

Industrial Chemistry in the new millennium is widely adopting concept of “Green Chemistry” to meet fundamental scientific challenges protecting health as well environment, while maintaining commercial viability. Use Ionic liquids (IL) fit nicely into this bill with remarkably cutting required reaction time and improving yields purity desired products. Other three more rapidly emerging areas Gre...

In order to apply ionic liquids (ILs) to the separation of rare earth metals, liquid-liquid extraction of a series of rare earth elements into the ILs was investigated mainly using 1-octyl-3-methylimidazolium bis(trifluoromethyl sulfonyl) imide, [C8mim][Tf2N], with N,N-dioctyldiglycol amic acid (DODGAA) as the extractant. A higher selectivity was exhibited for the heavier rare earth elements as...

A kinetic model to predict the relative intensities of the atomic C/H/N/O emission lines in laser-induced breakdown spectroscopy (LIBS) has been developed for organic compounds. The model includes a comprehensive set of chemical processes involving both neutral and ionic chemistry and physical excitation and de-excitation of atomic levels affecting the neutral, ionic, and excited-state species ...
