Salt-like cluster ions of the ([cation](n)[anion](n-1))(+) type are commonly composed of mono-atomic, inorganic components. Clusters containing organic ions are also known, with nitrogen-centred cations being particularly prominent. However, sulphur-centred analogues, such as organic sulphonium salts, represent a notable exception. Fast atom bombardment and liquid secondary ion mass spectrometr...

Saeed Baghery was born in Amol/Mazandaran (Iran) in 1985. He completed his B.Sc. in Pure chemistry in 2009 from Islamic Azad University of Amol, Mazandaran, Iran. He was graduated from M.Sc. degree under the supervision of Dr. Seyed Mohammad Vahdat in Organic Chemistry from Islamic Azad University of Amol, Mazandaran, Iran. He is currently Organic Chemistry Ph.D student under the supervision of...

The determination ofthe so-called 'ethereal sulphate content' of urine is a simple analytical procedure, and there are many reports in the literature which show that the administration of phenols to experimental animals is followed by an increased excretion ofethereal sulphates in the urine. On the other hand, because of the difficulties which have usually been encountered, relatively few ether...

The use of laser microprobe mass spectrometry (LMMS) for the structural characterization of thermolabile quaternary phosphonium salts has been evaluated. A comparison has been made between LM mass spectra obtained by direct analysis of "neat" organic salts and the corresponding "matrix-assisted" LM mass spectra. Main limitations of LMMS for the direct analysis of neat organic salts (i.e., no ma...

The solubility of lithium salts, found in solid-electrolyte interface (SEI) films on the anode surface in lithium ion battery cells, has been examined in organic solvents through atomistic computer simulations. The salts included lithium oxide (Li2O), lithium carbonate (Li2CO3), lithium oxalate ([LiCO2]2), lithium fluoride (LiF), lithium hydroxide (LiOH), lithium methoxide (LiOCH3), lithium met...

The effects of 15 inorganic and organic acid potassium salts on hydrothermal decomposition of glucose, fructose and 5-hydroxymethylfurfural (5-HMF) were investigated at 180°C. The rate constants for glucose, fructose and 5-HMF decomposition with anions were calculated by a pseudo first-order equation, and the impact factors of the rate constants were calculated, to demonstrate the catalytic eff...

It is known that lecithin, a zwitterionic phospholipid, self-assembles into spherical reverse micelles in organic solvents. We have explored the effects of adding inorganic salts to lecithin organosols. Salts are insoluble in organic solvents, and hence their effects on reverse self-assembly have rarely been studied. Our studies show, however, that salts can indeed be dissolved in organic liqui...

The effects of salts on the solubility of amphiphilic organic molecules are of importance to numerous atmospheric, environmental, and biological systems. A detailed picture of the influence of dissolved atmospheric salts, NaCl and Na(2)SO(4), on the adsorption of hexanoic acid at the vapor/water interface is developed using vibrational sum-frequency spectroscopy and surface tension measurements...

Crown ether complexation solubilizes organic and inorganic salts in nonpolar media. Induction of crystallization from such solutions can result in crystallization of the free salt rather than the complex. This affords the opportunity to examine solvent effects on the crystallization of salts and other polar materials, leading to the modification of crystal shape and lattice. This approach, whic...

A broad and simple method permitted halide ions in quaternary heteroaromatic and ammonium salts to be exchanged for a variety of anions using an anion exchange resin (A(-) form) in non-aqueous media. The anion loading of the AER (OH(-) form) was examined using two different anion sources, acids or ammonium salts, and changing the polarity of the solvents. The AER (A(-) form) method in organic s...
