In view the of wide scope of structural information of biomolecules in biocompatible ionic liquids (ILs) in various applications including chemical and biochemical, it is essential to study the productive preferential interactions between biological macromolecules and biocompatible ILs. We have therefore explored the stability and activity of α-chymotrypsin (CT) in the presence of five ILs from...

This paper reviews studies on dissolution, derivatization, and nanomaterial processing of chitin using an ionic liquid as useful media. Because chitin is the second most abundant polysaccharide on the earth after cellulose, there is major interest in conversion of native chitin resources into various useful materials after proper dissolution in suitable solvents. For the derivatization and nano...

The inhibition of mild steel corrosion in 1 M HCl solution by some ionic liquids (ILs) namely, 1-hexyl-3-methylimidazolium trifluoromethanesulfonate [HMIM][TfO], 1-hexyl-3-methylimidazolium tetrafluoroborate [HMIM][BF4], 1-hexyl-3-methylimidazolium hexafluorophosphate [HMIM][PF6], and 1-hexyl-3-methylimidazolium iodide [HMIM][I] was investigated using electrochemical measurements, spectroscopic...

Ionic Liquids are low melting salts (up to 100° C) and represent a new class of solvents with unusual physico-chemical properties. In the present work ionic liquids have been used as reaction media for the synthesis of phenylacetylphenylglycine and of phenylacetylphenylalanine. 3 ionic liquids: 1-Octyl-3-methylimidazolium tetrafluoroborate, 1-Butyl-3-methylimidazolium hexa fluorophosphate and 1...

This paper describes the separation and detection of five inorganic anions (I - , BrO3 NO2 Br NO3 -) by capillary ion chromatography using 1-alkyl-3-methylimidazolium-coated columns UV at 210 nm. The salts imidazolium (IM) ions (C2-, C4-, C6-, C8-, C10-, C18-IMs) are a family ionic liquids were newly examined as permanent coating reagents on triacontyl (C30) -bonded silica reversed phase column...

The electrochemical reduction of Fe(III) to Fe(II) in the ionic liquid (IL) mixture of 1-ethyl-3-methylimidazolium ethylsulfate, [C(2)C(1)Im][EtOSO(3)], and 1-butyl-3-methylimidazolium tetrachloroferrate (III), [C(4)C(1)Im][Fe(III)Cl(4)], was monitored in situ by X-ray photoelectron spectroscopy (XPS).

In the title compound, C(13)H(23)N(2)O(2) (+)·Br(-), the octyl chain has an all-trans conformation. In the crystal, the cations are linked by C-H⋯O bonds into a zigzag chain along the b axis. The bromide anions further link the chains via C-H⋯Br inter-actions into a two-dimensional array parallel to the ab plane. An O-H⋯Br interaction is also observed.

New experimental data on the thermodynamic properties of imidazolium-based ionic liquids (ILs) and {IL + water} solutions are presented. The isothermal (vapor liquid) phase equilibrium (VLE) density binary mixtures composed 1-ethyl-3-methylimidazolium formate, [EMIM][HCOO], or acetate, [EMIM][CH3COO], water demonstrated. were measured at temperatures from 298.15 to 348.15 K over a wide IL mole ...
