In recent years, great progress has been made in the dissolution of cellulose with ionic liquids (ILs). However, the mechanism of cellulose dissolution, especially the role the IL cation played in the dissolution process, has not been clearly understood. Herein, the mixtures of cellulose with a series of imidazolium-based chloride ionic liquids and 1-butyl-3-methyl pyridinium chloride ([C(4)mpy...

Most commercial anion exchange membranes (AEMs) deploy quaternary ammonium moieties. Alternative cation moieties have been explored in AEMs for fuel cells, but there are no studies focused examining alternative tethered cations ionic separations—such as organic acid transport via electrodialysis. H-cell and conductivity experiments demonstrate that benzyl 1-methyl imidazolium groups polysulfone...

Concentrations of volatile organic sulfur compounds (VOSC) were measured in water and sediment columns of ditches in a minerotrophic peatland in The Netherlands. VOSC, with methanethiol (4 to 40 nM) as the major compound, appeared to be mainly of sediment origin. Both VOSC and hydrogen sulfide concentrations decreased dramatically towards the water surface. High methanethiol and high dimethyl s...

Titanium dioxide nanoparticles play a crucial role in the production of hydrogen gas evolution. Among four polymorphic phases TiO2 (anatase, rutile, brookite, and (B)), anatase phase shows good photo activity catalytic applications. We prepared single anatasephase usinga facile one-step ionothermal method with existence 1-(3,6-dioxa heptane) 3-methyl imidazolium methane sulfonate IL[DOMIMS]. Th...

In this study, an experimental approach based on the isochoric pressure drop principle was implemented to measure (at low equilibrium pressure, 1.3–3.6 bar) solubility and binary diffusivity of CO2 (constant variable) in four imidazolium-based room-temperature ionic liquids (RTILs), namely, 1-ethyl-3-methylimidazolium acetate ([emim][Ac]), dicyanamide ([emim][DCA]), methyl sulfate ([emim][MeSO4...

The asymmetric unit of the title compound, 2C20H22N3O3(+)·SO4(2-)·H2O, contains four cations, two sulfate anions and two lattice water mol-ecules. One of the four cations shows a different conformation of the hy-droxy-ethyl group; the remaining three are all essentially superimposable. Two cations exhibit two-site orientational disorder [ratios = 0.524 (5):0.476 (5) and 0.616 (6):0.384 (6)] of ...

In the title compound, C(5)H(9)N(2) (+)·0.5C(2)O(4) (2-)·C(2)H(2)O(4)·H(2)O, the anions, cations and water mol-eculars are linked by N-H⋯O and O-H⋯O hydrogen bonds which define a tightly bound three-dimensional structure. The title compound is a layered structure as viewed along the a or c axis; one layer contains water and oxalic acid mol-ecules, the other the imidazolium cation. The C atoms o...

The title compound, C12H20N2O4, represents one example of a zwitterionic imidazolium salt with a carboxyl-ate group at the 2-position of the imidazolium ring. The dihedral angle between the heterocyclic ring and the carboxyl-ate group is 31.3 (1)°. The side chain linking the N atom of the ring and the methine C atom has a gauche-anti-anti conformation [torsion angles = -60.3 (2), -175.7 (2) and...

An efficient solventless one-pot procedure for the synthesis of imidazolium-based ionic liquid under microwave irradiation is described in which 1-methylimidazole was modified by organosilane (3-chloropropyl triethoxysilane). This ionic liquid 1-methyl-3-[(triethoxysilyl)propyl]imidazolium chloride (TMICl) is immobilized on Mechanically activated Fly Ash (MFA) by co-condensation method to d...

Six 1-alkyl-4-tridecafluorooctyl-1,2,4-triazolium triflimides 2a–f and 4-amino-1-tridecafluorooctyl-1,2,4-triazolium triflimide (4) were prepared from the respective iodides 1a–f (1a, 2a: n-propyl; 1b, 2b: n-butyl; 1c, 2c: n-hexyl; 1d, 2d: n-heptyl; 1e, 2e: n-octyl; 1f, 2f: n-decyl) and iodide 3 by ion metathesis. Compounds 2a and 4 are liquid at room temperature. Two liquid fluorous imidazoliu...
